Description

Insect trapping and killing device and method

Technical Field

The invention belongs to the field of agriculture, and particularly relates to an insect trapping and killing device and an insect trapping and killing method.

Background

Peach fruit borer (Carposina sasakii) eats delicious fruits, is a main pest of apples and jujubes produced in China, Korea and Japan, and also has damage to plums, pears, apricots and peaches in some areas. Peach fruit borers occur in late spring until autumn. Peach fruit borer larvae can dig into the fruit for damage and are therefore difficult to control by pesticides.

Apple leafworm (Adoxophyes orana) is a type of leafworm that is widely distributed in Asia and Europe and is a hazard to a wide variety of fruit crops. Leaf roller moth larvae feed on the leaves and pulp, are extremely harmful to apples and may occur simultaneously with peach fruit borers in orchards.

In the world, codling moth (Cydia pomonella) is a main pest of apples, pears and walnuts, and the codling moth larvae can cause damage after drilling into fruits and are fruit-eating pests, and are difficult to control through pesticides to influence the income of fruit growers.

Chilo suppersalis (Chilo suppersalis) is a main pest of rice in the whole China, and is particularly serious in northeast China; corn borer (Ostrinia furnacalis) is a main pest on Chinese corn, and the two pests continuously and irregularly occur from the middle ten days of May to October, so that farmers are difficult to master the accurate pesticide spraying time, only can continuously use a large amount of pesticides, pests resist the pesticide, the labor of the farmers is increased, and the excessive use of the pesticides causes the pesticide residue to exceed the standard and causes pollution to the environment.

The sweet potato weevil (Cylas formicarius) is a weevil, is a main pest on sweet potatoes worldwide, has an active period of 6 to 8 months in one year, mainly takes tubers as food, is difficult to control and has high cost; as long as the fruit is infested with this pest, it becomes stale and unmarketable.

The sweet potato weevil generates 6-8 generations in Guangdong one year, and has obvious generation overlapping phenomenon. The adult overwintering method mainly comprises the steps of overwintering in the field and in the stored potato blocks and in hidden positions such as stems, leaves and soil seams; eggs, larvae and pupae can also overwinter in potato pieces. The early spring adult insects firstly finish 1 generation on the overwintering plant and then are transferred to the field for harm. The imagoes have weak flying ability, are afraid of direct sunlight and have false death. Eggs are scattered below the cortex of the potato tuber, and then are laid on the thicker potato tendrils, the egg laying hole is generally covered with colloid, and each female can lay 30-200 eggs. The whole larval stage lives in the potato blocks or the vine heads, the interior of the potato blocks is eaten by the larvas to form an unshaped bent tunnel, the tunnel is filled with insect feces, the damaged potato blocks are stink and bitter due to the invasion of pathogenic bacteria caused by wounds, and the aged larvas pupate at the position close to the surface layer of the tail end of the tunnel.

Anoplophora chinensis (anophophora chinensis) is a large-scale long horn beetle, which damages the trunks of citrus and certain nut trees, and also damages ornamental trees. Anoplophora glabripennis (Anoplophora glabripennis) is a major pest of forest and ornamental trees in china.

Coffee Kazu-shaped longhorn beetles (xylotreuchus quadripes) are longicorn beetles which can damage Yunnan Arab coffee trees and cause death of the trees, and are a potential threat to the coffee industry.

Drosophila, especially oriental fruit fly (Bactrocera dorsalis), melon fly (Bactrocera cucurbitae) and citrus fruit fly (Bactrocera minax) are important pests of fruits, melons and certain vegetables in china. They like the taste of certain amines, which is the taste of food for adult fruit fly.

Empoasca vitis, a semipteroid insect, damages Chinese grapes and tea leaves by sucking the sap of the leaves and soft stems. Empoasca vitis preferring tea plant volatiles including trans-2-hexenal, cis-3-hexen-1-ol, geraniol, linalool and trans-ocimene.

For different pests, it may be good if the effective pesticide can be sprayed timely and accurately, but the harm of spraying a great amount of pesticide is still very much, for example: 1. the health of the user is harmed; 2. pesticide residues may be left on the fruits; 3. inevitably, spraying a large amount of insecticide will kill a large number of beneficial insects, resulting in outbreaks of secondary insect pests, such as tetranychus urticae, leaf miner on fruit trees and rice planthopper; 4. the requirement for labor is increased by frequently spraying the insecticide, and the production cost is increased; 5. crops usually growing on hillsides, such as jujube, are inconvenient to spray with insecticide; 6. polluting water source and harming environment.

The peach fruit borer female insects release a sex pheromone in the mating period to attract the peach fruit borer male insects to mate, so that the reproduction of the peach fruit borer female insects depends on the communication method. The sex pheromone of peach fruit borer has two components: z, 13 Eicosen-10-one (Z, 13 Eicosen-10-one) and Z, 7 eicosatriene (Z, 7 Tricosene).

The peach fruit borer can be induced by using Z, 13 Eicosen-10-one (Z, 13 Eicosen-10-one) or by mixing Z, 13 Eicosen-10-one (Z, 13 Eicosen-10-one) and Z, 7 eicosatriene (Z, 7 Tricosene). In general, during monitoring, the lure core containing the sex pheromone is placed in a monitoring box with a sticky plate at the bottom, and the male peach fruit borer is attracted by the sex pheromone of the peach fruit borer released by the lure core to fly into the monitoring box and is stuck by the sticky plate. The monitoring box is suitable for evaluating the quantity and occurrence condition of the field quantity of the peach fruit borers, but if a mating interference method is adopted and is used in a large quantity as a method for controlling the peach fruit borers, the pheromone is too expensive, so that the product price is higher.

The use of Z, 13 Eicosen-10-one alone (Z, 13 Eicosen-10-one) or a mixture of Z, 13 Eicosen-10-one (Z, 13 Eicosen-10-one) and Z, 7 eicosatriene (Z, 7 Tricosene) can control the peach fruit borer hazard by disrupting mating. Interference of the male moths with chemically synthesized sex pheromones does not allow the true female moths to be found, and mating does not occur unless it is met by chance. The mating interference method is closely related to the population base number in the orchard, and when the quantity of the peach fruit borers in the orchard is large, the mating interference technology is used and must be matched with a proper pesticide to reduce the insect pressure. In the case of disturbed mating, since male moths will persist, real female moths are sought after one time until after several days to exhaust energy.

Therefore, the possibility that the male moth meets the female moth still exists, and the machine rate is higher than that of a system for directly trapping and killing the male moth, because in the direct trapping and killing system, the male moth only has one chance to die, the trapping and killing rate is improved, and the mating probability is further reduced. However, in the past, because the attractant for the pests has short duration, the labor cost is high when the attractant is frequently replaced, and in addition, the price of the used monitoring trapping box or equipment is not suitable for large-scale commercial use and is too high, the prevention and control technology which can be used for preventing and controlling the pests in a large area is not available.

The mating disruption technique of peach fruit borer (see chinese patent CN102823590A) uses 1500 (100/acre) sex pheromone divergers per hectare, and each diverger contains 65 mg of sex pheromone. Therefore, 97.5 g pheromone (6.5 g/mu) is needed to be used per hectare, and the cost of the peach fruit borer sex pheromone is high, so that farmers cannot afford the technology, and the technology cannot be popularized commercially.

Female apple leaf rollers release a pheromone consisting of cis-9-tetradecene acetate (Z, 9 Tetradecen-1-yl acetate) and (Z, 11 Tetradecen-1-yl acetate) in a ratio of 4: 1. Female moths use this pheromone to attract male moths to mate. Like carposina niponensis, the pheromone of the apple leafroll moth can be used to control release devices to control this pest by disrupting mating. When pheromone-disrupted mating technology was used to control such insects, a minimum of 33 dispensers containing 250 mg of pheromone per acre were used. Thus, 125 grams of pheromone (8.3 grams/acre) per hectare is required. Like the sex pheromone of the peach fruit borer, the price of the pheromone of the apple leaf roller is very expensive, and farmers can hardly bear the pheromone. For fruit growers planting apples, apple leaf roller moth pheromone and peach fruit borer pheromone are needed to be used at the same time, so that the cost is higher, and the large-area commercial popularization and use cannot be realized.

The female codling moth releases a pheromone with a component of trans, trans-8, 10-Dodecadien-1-ol (E, E8, 10 Dodecadien-1-ol). This pheromone is widely used to control codling moth by interfering with mating in europe, north america, south africa and australia. Currently, china has not controlled the damage of codling moth by using this pheromone. Mating disruption of codling moth requires 200 grams of active ingredient per hectare (13.3 grams/acre).

The semiochemicals released by the female chilo suppressalis comprise cis-11-hexadecenal (Z, 11 Hexadecen-1-al), cis-13-hexadecenal (Z, 13 Hexadecen-1-al) and cis-9-hexadecenal (Z, 9 Hexadecen-1-al) in a ratio of 48: 6: 5. This pheromone was used experimentally to control chilo suppressalis at 6-7.5 grams per hectare. Pheromones have also been used for trap control at rates of 4 and 10 mg per hectare (0.27 and 0.67 per acre).

The female Asiatic corn borer (Ostrinia furnacalis) produces a pheromone consisting of (Z) -12-tetradecenyl acetate (Z, 12 Tetradecen-1-yl acetate) and (E) -12-tetradecenyl acetate (E, 12 Tetradecen-1-yl acetate) in a ratio of 1: 1 to 2: 1. The pheromone is experimentally used for controlling chilo suppressalis by matching with an insecticide through an interference mating method, and the using amount of the pheromone per hectare in the season is 50-150 mg (3.3-10 mg per mu). The use of pheromone monitoring boxes (together with the insecticide) was also used for trap control at a rate of 4 and 10 mg per hectare (0.27 and 0.67 per acre).

Both female and male flies of the genus drosophila are attracted by the smell of amine-containing food and can be used as one of the attractant components for attracting fruit flies effectively.

The female weevil produces a very potent pheromone (Z) -3-12 alkenyl ester (Z, 3 Dodecenyl butenoate) for attracting male weevils. Such pheromones have been used to trap control using a large number of traps.

The sex pheromone is prepared by mixing 4-n-heptyloxybutanol (4- (n-heptyloxyl) -1-ol) and 4-n-heptyloxybutyraldehyde (4- (n-heptyloxyl) -1-al) in a ratio of 1: 1, and can attract female insects and male insects. Pheromones released from Anoplophora chinensis (Anoplophora chinensis) contain only 4-n-heptyloxybutanol (4- (n-heptyloxyxy) -1-ol).

The male Bulbophyllum caucasianum which is deinsectization coffee produces pheromone with the component of (S) -2-hydroxy-3-decanone, and can attract female insects and male insects at the same time.

The sweet potato weevil, the anoplophora glabripennis and the coffee deity tiger longhorn are not objects of mating interference, but can be objects trapped and killed in a large quantity.

From the above, it can be seen that the use of mating disruption techniques achieves a hazard control effect similar to but more often than that achieved with insecticides alone. However, since pheromones are expensive and used in large quantities, the cost is difficult to reduce.

In the prior art, other trapping and killing technologies are used for preventing and controlling codling moth (codling moth) and Chilo suppersalis (Chilo suppersalis), but the trapping and killing are mainly performed by using sticky glue, the main purpose is monitoring, the sticky plate needs to be replaced frequently, the use cost and the labor cost are high, and the insect trapping and killing are not complete.

Disclosure of Invention

It is an object of the present invention to overcome the disadvantages of the prior art and to provide an insect trapping and killing device which requires less pheromone than the interferential mating technique, requires a lower number of pheromone releasers and is cost and labor saving. Because the male moths can be killed once the male moths fall on the device used by the trapping and killing mechanism, the male moths can be killed only by appearing once, and the efficiency is improved. The trapping and killing device is provided with a bearing object, the pesticide is only used on the surface of the bearing object, does not contact fruits, does not need to be sprayed in an orchard comprehensively, has the advantage of no residual pesticide on products, and has the advantages of small dosage of the pesticide used in the trapping and killing system, safety and environmental protection, and only needs to be used once a year.

The other object of the present invention is to provide a method for attracting and killing insects.

The insect trapping and killing device comprises: a. an attractant; b. a releaser for carrying an attractant; c. an insecticide coated on the outer surface of the releaser;

The attractant comprises one or more of insect pheromone, plant volatile attractant or amine-containing attractant, a slow release carrier, an antioxidant, an ultraviolet-resistant stabilizer and a solvent, wherein the slow release carrier can be rubber head, wood powder, wax, vermiculite, perlite, silica gel, clay and the like.

Wherein when the attractant adopts insect pheromone, the weight ratio of the insect pheromone to the antioxidant to the ultraviolet-resistant stabilizer to the slow-release carrier in the attractant is (1-10) to (1-2) to (0.5-1.0) to (2000-3000); wherein the insect pheromone is selected from one or more pheromones of peach fruit borer, codling moth or other moth family Olethritiniae species, or Chilo suppressalis, Asian corn borer (Ostrinia furnacalis) or other Crambidae family Cnaphalocrocodiella species, or sweet potato weevil (Cylas formicarius), adult beetles including but not limited to Astrocarya (Anoplophora) or Kazu Heterophyllus (Xylotreus quadripes). When the solvent is added, the formula proportion of the attractant is that the weight ratio of the insect pheromone, the antioxidant, the ultraviolet-resistant stabilizer, the solvent and the slow-release carrier is (1-10): (1-2): (0.5-1.0): (400-.

Wherein the antioxidant is preferably Butylhydroxytoluene (BHT), and the solvent is selected from pentane and vegetable oil.

When the attractant is plant volatile attractant, the plant aromatic of Empoasca vitis is preferably used.

Wherein the weight ratio of the plant volatile attractant to the antioxidant to the ultraviolet-resistant stabilizer to the sustained-release carrier in the attractant is (700-.

Wherein the attractant can also adopt amine-containing attractant which is attractive to fruit fly (Bactrocera), the weight ratio of the amine-containing attractant substance to the slow-release carrier is (20-80) to (80-20), the amine-containing attractant is preferably ammonium acetate, the carrier is one or more selected from vermiculite, perlite, silica gel, clay and wood powder, and each releaser is preferably filled with 10-30 mg of attractant.

The pheromone has hydrophobicity, and can be dissolved in hydrophobic carriers such as wax, rubber and the like. In contrast, the amine-containing compounds in the fruit fly attractant are highly hydrophilic, and are very inconvenient to use alone or directly due to water absorption and liquefaction in the air, and we find that the amine-containing compounds can solve the problem by mixing with carriers such as cellulose, wood powder, bamboo powder, vermiculite, perlite, silica gel or clay, and the like, and subpackaging the mixture into small bags according to needs, so that the content can be ensured, and the stability of the amine-containing attractant can be ensured, and we have found that the high-density polyethylene synthetic paper meets the packaging requirements of the mixture.

The attractant-bearing releaser can be a plate, a container, a bag or a material capable of being wound on the branches of trees.

The attractant-bearing releaser of the invention is preferably a bag made of high-density polyethylene synthetic paper (spin-bonded polyethylene), polypropylene fiber (non-woven fabric), PVC (less than 0.5 mm), polyethylene/starch board (less than 0.5 mm), cotton fabric (cloth) or PLA (polylactic acid) polylactic acid non-woven fabric, and the materials have high strength and good waterproofness, and the pores of the materials are enough to release the attractant in the bag.

The attractant-carrying release of the present invention may also be a container with one, two or more holes.

The container may be, for example, a plastic bottle, a trap barrel, a waterproof bag, a waterproof box, a conical container, various containers made of cardboard, and the like, but is not limited thereto. All containers must have water resistance and resistance to uv oxidation. As an example, a disposable plastic container made of a material having waterproof property and ultraviolet ray oxidation resistance can be used in consideration of convenience. Moreover, whatever the container, it must be able to satisfy the feature of remaining intact without being affected by the weather, placed in the orchard for several months in succession. By way of example, it may be 1-5 months, or more. This is also the main reason why the container of the present invention is made of a material having water-repellent properties and ultraviolet ray oxidation-resistant properties.

The releaser is preferably economic and transportable, the flat package of the device can effectively utilize the storage and transportation space, and the degradability and environmental protection are also important to consider; meanwhile, under the environment of sunshine, wind and rain, the tree trunk is hung on the tree trunk or exposed in the field, and the integrity and the functionality of the tree trunk are ensured for at least not less than one month. This requires that the device be uv protected and strong enough not to be damaged and fall out under strong winds.

The outer surface area of the release is preferably 24-1536 square centimeters and the outer surface of the release in the device must be such as to attract a large number of insects falling and contacting the insecticide on its surface. When the surface area of the releaser is larger than 1536 square centimeters in rating, the insect-proof effect can be more effective, but the increase of the surface area of the bearing object can be restricted by factors such as cost, convenience and the like.

The insecticide is insoluble in water and can be a synthetic pyrethroid insecticide, preferably, the insecticide is a pyrethroid insecticide, including but not limited to: deltamethrin, alpha-cypermethrin, beta-cypermethrin, bifenthrin and fenvalerate, preferably deltamethrin.

These insecticides are commercially available. It should be noted that the insecticide applicable to the present invention is not limited to the above-described ones, and any insecticide having the following functional characteristics can be used as long as it can be coated on the outer surface of the container. The functional features include: a. the selected insecticide is effective on target insects, and has the characteristic of rain wash resistance and lasting effect for more than 1 month; c. the selected insecticide is not easily decomposed by ultraviolet rays; d. the selected pesticide has low toxicity to human skin.

The insect trapping and killing device provided by the invention can attract insects by the volatile attractant to the releaser carrying the attractant, and then the insects contact with the outer surface of the releaser coated with the insecticide to achieve the trapping and killing purpose. Since the outer surface of the releaser is coated with the insecticide, the insects can be killed even if they do not enter the releaser but merely stay on the outer surface of the releaser.

It should be noted that the container is one type of releaser, and the amount of attractant in the container is not directly related to the size of the container, the size of the aperture and the area of the orchard applied. However, in any event, the amount of attractant needs to be sufficient to attract a large population of insects to rest on the outer surface of the container. Since the attractant will be slowly released over time at a rate, the amount of attractant used will vary, taking into account the insect's response to the spatial concentration of the attractant and the actual field age. Some insects are very sensitive to their pheromones and can be attracted at 0.001mg, whereas above this dose they cannot be attracted, and experiments have shown that it is not economical to have too low an amount of attractant so that frequent addition of attractant is required.

According to another aspect of the present invention, there is provided a method of trapping and killing insects, which employs the insect trapping and killing device.

The insect trapping and killing device is placed among crops to be protected according to the number of 1-30 per mu. We found through research that the distance for the peach fruit borers to be attracted by pheromone is 4m, so the suitable distance between the devices is 8m (the effective radius is 4m), and the density is also suitable for the apple leaf rollers, the codling moths and the sweet potato weevils. The data show that the attraction action distance of the pheromone to the chilo suppressalis is 15m, so that the arrangement density of the effective devices is 5 per mu, the density is also suitable for the corn borers, the empoasca vitis and the carina poiretii, and the arrangement of 1 device per mu is suitable for the anoplophora nivea.

to minimize the labor required to control the target insects, the attractants required by the present invention need to be continuously effective over the period of time that the target insect pest is being controlled. Taking fruit moth, longicorn and tea tree hemiptera insects as examples, the action period of the attractant is from the first generation of the target pest imago to the end of the harvest of the target crop. Taking rice-stem borers and corn borers as examples, the action period needs to begin to occur or migrate from the spring of the target insect pest imagoes to the target crops for completing the harvest.

Compared with the situation that the insecticide is directly sprayed to crops, the insect trapping and killing device can effectively control the number of target pests in the field. The device is a novel trapping and killing device, and farmers do not need to use insecticides to control insects. The interference mating technology and the trapping technology are already applied to the prevention and treatment of the harm caused by leaf rollers, codling moths, lesser leafhoppers, corn borers, chilo suppressalis and the like, but the trapping technology used for the pests at present is limited to the utilization of sticky plates or water-containing containers (such as water basins) to kill the trapped target pests, and the attracting cores, the sticky plates and the water basins need to be frequently replaced, so that the effect is short, the labor cost is high, and the effect is very little. The novel device has remarkable insecticidal effect, and is still effective for coleoptera pests, sweet potato weevil, anoplophora chinensis and carina carinata, particularly for pests which are inapplicable to pheromone mating interference technologies such as hemiptera pests, pseudobulbus vitis vinifera and the like. The device eliminates the need of spraying insecticide on orchard crops while trapping and killing insects, so that not only is a good fruit protection effect achieved, but also the safe edibility of fruits is maintained, and a good technical effect can be achieved in the aspect of preventing and treating insect harm.

The attractant is placed in the envelope bag, and the adhesive is sprayed on both sides of the outer surface of the envelope bag, so that the target pests attracted by the attractant in the envelope bag can be stuck and die after staying on the surface of the envelope bag.

the method can facilitate the collection of the number of attracted target pests in experiments.

The attractants placed in each envelope bag are two peach fruit borer pheromone attractants described in the above example 4, the two attractants 1 and 2 are placed in the same bag, and 20 envelope bags with the attractants placed in the outer glue are placed in a jujube tree garden of 5 mu, and the arrangement is four rows and five columns, and the spacing and the column spacing are both 10 meters.

TABLE 3 field test results of the effect of the external surface area of the load on the trapping effect

(Total amount of peach fruit borers stuck to the outer surface of 4 envelope bags per experiment)

Number of days	Test 1	test 2	Test 3	test 4	Test 5
						0-7	9	22	24	17	14
8-14	11	21	25	22	18
						15-21	8	19	30	22	25
22-28	5	15	18	25	28
						Total of	33	77	97	86	85

All traps were effective, with test 1 being the least effective, indicating too little contact surface area. Test 2 has a smaller number of heartworm arrested than tests 3, 4, 5, but this difference is not statistically significant, so it is concluded that the optimum surface area for the selected touchdown region is between 90 and 1536 square centimeters.

Example 8: control tests of different insecticides on the killing effect of peach fruit borers in a laboratory environment, a series of pyrethroid pesticides were tested to determine whether they are suitable for killing peach fruit borers.

A polypropylene bottle (diameter 2.5 cm, length 10 cm) with a volume of 50 ml is used, 2ml of acetone containing different pesticide raw medicines is added, the active ingredients of the pesticide raw medicines contained in the acetone are fully dissolved, the mixture is kept still for one day until all the solvent containing the acetone is volatilized, and different types of pesticides with different concentrations are attached to the inner surface of the bottle. A polypropylene bottle containing no insecticide and only 2ml acetone was also prepared as a control.

The 5 laboratory cultured peach fruit borers were placed in bottles that had been allowed to stand for 10 minutes, then transferred to empty PVC water cups, sealed with wet cotton cloth and rubber bands, allowed to air circulate, and observed after 24 hours. Each experiment was repeated 5 times.

TABLE 4 mortality of peach fruit borer 24 hours after 10 minutes exposure to different pyrethroid insecticides, respectively

mg/square centimeter	0.25	0.50	2.50	5.00
					Deltamethrin	70％	90％	100％	100％
Efficient cyhalothrin	80％	100％	100％	100％
					Cypermethrin	50％	70％	90％	100％
fenvalerate	30％	60％	80％	100％
					Biphenthrin	50％	80％	90％	100％
Controlled variable	0.0％	10.0％	0.0％	0.0％

Tests show that deltamethrin and lambda-cyhalothrin have the best effect on killing peach fruit borers.

Example 9: testing field pot life of insecticide attached to releasers of different materials in a device

In the devices of the present invention, the pesticide applied to the outer surface of the releaser is maintained in the field for an effective period of time which is critical to the effectiveness of such devices. Thus, we tested a series of different releaser materials to determine if the field useful life of the insecticide would therefore vary. The test materials were as follows:

High density polyethylene synthetic paper (spin-bonded polyethylene), polypropylene fiber (nonwoven), PVC board (0.5 mm), polyethylene/starch board (0.5 mm), cotton fabric (cloth) and pla (polylactic acid) polylactic acid nonwoven. All materials were one size (10cm x12 cm).

5 ml of deltamethrin solution or beta-cyfluthrin ethanol solution (0.12 mg/ml) is sprayed on both sides of all the materials, 5 micrograms of insecticide are attached to the surface of each square centimeter of the materials after air drying, and the test is repeated three times.

The releasers are respectively hung on the branches of the peach trees, and the releasers are hung in spring and the test is finished after summer.

and respectively cutting a small piece from each piece of material to return to the laboratory at the time points of 2, 4 and 6 months in the suspension outdoor, and putting 10 peach fruit borers and moths into a culture dish for each time aiming at each piece of cut material, so that the peach fruit borers and moths stay on the surface of the test material for 10 minutes. Thereafter, the test piece was transferred to a paper cup and the mortality was observed 24 hours later. The control group had no material containing the same insecticide hung outdoors.

TABLE 5 mortality of peach fruit borers in outdoor efficacy time test with different insecticides attached to the releaser materials

The outdoor persistence of the high-efficiency cyhalothrin is superior to that of deltamethrin; the effects of the cotton, the high-density polyethylene synthetic paper and the polylactic acid non-woven fabric PP material are better.

Example 10: prevent and treat peach fruit borer field device

The field experiment for preventing and controlling peach fruit borers through the device is carried out in the Yunnan green jujube garden, and the device effects of three kinds of use densities are tested. A 12 x10cm envelope coated on its outer surface with 5 micrograms deltamethrin per square cm was used. In late April, the peach fruit borer adults were hung on branches approximately 1.8 meters high before they emerged. The envelope bag made of the peach fruit borer non-woven fabric PP material contains the attractant 1 and the attractant 2 which are described in the embodiment 4.

And randomly selecting 100 fruits on 5 trees in the center of the test area to judge the infection condition, and if obvious wormholes appear, judging that the trees are damaged.

TABLE 6 sum of percentage of damaged fruits in green jujube orchard harvesting period

From the above experiments, it can be seen that the harm of the orchard using the peach fruit borer control device is significantly lower than that of the blank control, and in the orchards using 10 and 30 envelope bags per mu, the harm of the peach fruit borer is significantly lower than that of the conventional control orchards using full pesticide spraying.

Example 11: field test using attractant device for preventing and controlling apple leaf rollers and peach fruit borers simultaneously

The field experiment of using the device to simultaneously control the apple leaf rollers and the peach fruit borers is carried out in the Liaoning apple orchard, and the effects of the trapping and killing devices with three densities are compared. A 12 x10cm Tyvek envelope was used with 5 micrograms deltamethrin per square cm of the surface of the bag. In late April, the apple leafroller moth and peach fruit borer are hung on a branch about 1.8 meters above the ground before the adult apple leafroller moth and peach fruit borer occur. The attractants in the envelope bag are a peach fruit borer pheromone attractant (attractant 1 and attractant 2 described in example 4) and a codling moth pheromone attractant (codling moth pheromone attractant described in example 4).

Each envelope bag contains pheromone attractant releaser for apple leaf roller moth and peach fruit borer

And randomly selecting 100 fruits on 5 trees in the center of the test area to judge the damage condition, recording the number of the fruits damaged by the apple leaf roller and the peach fruit borer, and calculating the damage rate.

TABLE 7 statistics of fruit damage by apple leafroller and peach fruit borer at harvest time of apple orchard

The effect of controlling the apple leaf rollers and peach fruit borers in orchards with 5, 10 and 20 devices per mu is superior to that of blank areas without treatment and chemical control areas with traditional pesticide spraying. The experiment shows that different pheromone attractants can be used by the same releaser aiming at different target pests at the same time to form a device which saves cost more effectively, the limitation that one biocontrol means can only aim at one target pest in the past is changed, and the two insect attractants have synergistic action.

Example 12: field trials using a device with a codling moth attractant releaser

aiming at codling moth, the experiment of using the device of the codling moth attractant releaser in the fields is carried out in Gansu apple orchard, and the effects of the devices with three densities are compared.

In late April, the codling moth was hung at a branch 1.8 meters high above the ground before it appeared. The codling moth pheromone attractant releaser is described in example 4. Tyvek (Tyvek) is an excellent nonwoven product from dupont, a spunbond olefin made with high density polyethylene fibers that possess balanced physical properties.

Each envelope bag contains the codling moth pheromone attractant

Randomly selecting 100 fruits on 5 trees in the center of the test area to judge the infection condition, recording the number of the fruits damaged by the codling moth, and calculating the damage rate.

TABLE 8 fruit hazard rate to codling moth at harvest stage in apple orchard

The use of 5, 10, 20 device systems per acre outperformed the untreated control and orchards using traditional pesticide sprays.

the device provides an effective control method for controlling the plutella xylostella of the subfamily Plutella xylostella. We can therefore reasonably conclude that moths of other subfamily of tortricidae can also use this device to reduce harm by their respective pheromones.

Example 13: field control experiment using Chilo suppressalis slow-release attractant releaser

Experiments for preventing and controlling chilo suppressalis in the field are carried out in Jiangsu paddy fields, and the device effects of the two densities are compared.
