Description

Fly entrapment formula using reduced amount of attractant

The invention relates to a novel use of castor oil for stabilizing substances of flies insects and reducing the dosage.

The fruit flies (tephritid flies) belong to the Diptera and Tephritidae insects. There are 4,800 species in the world, and nearly 90 kinds of hazards are economically important. Among them, the Dacinae subfamily (Dacinae) The genus Bactrocera and the genus Dacine flies of the genus Dacus are more harmful. At present, the main fruit fly ( Bactrocera dorsalis ), B. cucurbitae and Bactrocera ta u are the most important melon and fruit pests. These insects are distributed in Central Asia, Southeast Asia, Oceania and some African countries. Farmers call it "bee" or "melon bee" (for fruit fly and pumpkin fruit fly). There are 173 kinds of fruit species in the oriental fruit fly, and there are 89 species in 32 families in China; the fruit fly is the main economic pest of the cucurbit crop, which has more than 80 host plants, and 41 species of pumpkin fruit fly, such as melon. Melon, melon, courgette, bitter gourd, mountain bitter gourd, loofah, angular loofah, watermelon, melon, pumpkin, zucchini, flat-boiled, melon and other melon crops, when the situation is serious, the fruit can not be harvested completely. In Taiwan, due to the temperate climate, the host is indispensable, causing melons and fruit flies to occur all year round. It is difficult to control, often causing serious loss of fruits and fruits. Melons and fruit flies lay eggs under the peel, and the hatching larvae feed on the fruit. The mature larvae will leave the victim and sneak into the soil to dissipate the mites. Therefore, the eggs are not easy to control during the pupa period, and the control targets are mainly adult worms.

Agricultural pest control can be generally divided into three categories: physical control, biological control and chemical control. Nowadays, farmers mainly use chemical control for pest control, that is, chemical agents are applied. However, according to research reports, many chemical agents have reduced or even failed the efficacy of harmful insects. Farmers keep the beautiful appearance of crops to cater to consumers. Demand, has to increase the number of chemical sprays and drug concentrations, and even mixed a variety of agents, but this will not only achieve the effect of prevention and control, but also increase production costs, but also cause pesticide residues.

Furthermore, due to the rising awareness of environmental protection and health care, organic vegetables and fruits that emphasize the non-spraying of pesticides are becoming popular and become the first choice for consumption. However, organic fruits and vegetables are susceptible to insect erosion and affect the economic benefits of products. However, because the current biological control methods still have some shortcomings that are difficult to overcome, for example, there is a high degree of specificity between the control object and the natural enemies. It is necessary to individually identify the species, the species that cannot be completely eliminated, and the natural enemies used are extremely vulnerable to environmental factors. However, how to reduce the effect, etc., how to prevent crops from being harmed by insects by physical control methods, is a research topic for the industry; among them, the use of insect-adhesive paper has been widely used in the industry, and it is also one of the most convenient physical control methods. .

Another current chemical control method is to use many volatile substances in the natural environment, some of which can induce and assist insects to find habitats, food, spawning places, mating objects, etc., in order to maintain their lives or to progeny. Insects sense these "odors" through the olfactory function, allowing the same species or different species to communicate with each other and initiate specific behavioral responses. Such volatile substances are collectively referred to as semiochemicals, including pheromone, kairomone, spawning primers, repellents, and many other compounds (Nordlund, 1981; Howse et Al., 1998). The application of chemical communication materials in the field can change the behavior of pests, thereby controlling the development of their populations, achieving the purpose of pest management and reducing crop damage. A variety of chemical signaling materials can be used together to increase the trapping effect. For example, a feeding enhancer, a male attractant, a female pheromone and a quick-acting insecticide are added to a slime plate for use in the field control of the fruit fly ( Bactrocera oleae ), and the results are required for each olive tree control. The amount of pesticides has been reduced by one percent (Haniotakis et al., 1991).

In addition to detecting sensational sensation materials, insects also visually recognize different colors (Prokopy and Owens, 1983; Oseto, 2000). Different insects tend to prefer a particular preferred color, so the color itself is an insect attractant. Specific colors with insecticidal traps such as sticky paper, water trays, etc., can be used to trap insects to trap pests (Sivinski, 1990). The colors commonly used for testing in pest control research are white, blue, green, yellow, etc., all related to the reflection spectrum or wavelength of the host plant. There are many experimental results on the color of pest preference. For example, the peach aphid prefers yellow, the aster leafhopper prefers orange, the flower hummus prefers white or blue, and the apple fruit fly (Rhagoletis pomonella) tends to tend to red or yellow. In the field, the intensity of insects' color is affected by the position of the insect trap, the composition of the ground (background), the physiological state of the insect, and the wavelength of light projected on the trap (Robacker et al., 1990).

At present, more than 90% of the Dacine flies of the genus Bactrocera and Dacus are found to be methyl eugenol in the Dacliae subfamily (Dacinae). (ME)) or cue-lure (CL), a derivative of raspberry ketone. At least 176 males of this type of fruit fly are attracted to flies or raspberry ketones, while 58 are attracted to methyl clove oil. Among them, there are 73 species of agricultural pests recorded above, 41 species will be attracted to flies or raspberry ketones, and 22 species will be attracted to methyl clove oil.

At present, the control methods for cucurbit flies and pumpkin fruit flies mainly use a sex pheromones known as Cuelure to trap the males of these cucurbit flies, which are produced by hydrolysis to produce acetic acid and raspberry ketone. Producing attractiveness, the structure is as follows: In addition, there are also methods for controlling pesticides such as direct spraying of pesticides and spraying of toxic protein hydrolysates. However, when the fly itself is used in the field, the killing effect on the fruit fly population is not satisfactory. The relevant literature indicates that the fly fly has only 20% replacement rate for the labeled fruit fly, while the methyl clove oil is for the oriental fruit fly. There is an 85% re-catch rate. Another literature pointed out that the fly has no effect on the attracting of males who have not yet matured, and the effective attracting distance and sensitivity of ethnic detection have room for improvement, and the lure efficiency of the trapping material should be improved. Based on this, domestic products added methyl clove oil to reduce the concentration of the fly to 10% (fly scent), although it can effectively increase the stability of the product, but because of the two attractants of different standard pests, the cost It has not been reduced; and if it is only used as a control object in the field, in addition to increasing the cost of prevention, high concentration of methyl clove oil is also carcinogenic, which will increase the exposure risk of farmers.

Raspberry ketone is a stimulant of 176 species of Dacine flies, such as cucurbit flies, which is a kind of pheromone precursor of melon flies. Its structure is as follows: However, raspberry ketone has no field attracting effect in the solid state (because its volatility is extremely poor, it only has a attracting effect in a very short distance, about 10-20 cm). In recent years, the literature mentions a new raspberry ketone formate, 4-(3-Oxobutyl)phenyl formate or 4- (4) -(Formyloxyphenyl)-2-butanone (4-(4-formyloxyphenyl)-2-butanone): It can be used as a component to induce males of the fruit fly, which has a better attracting effect than the fly. However, because it is easier to decompose and produce crystals than the flies, it is not easy to preserve and the effect in the field is unstable, and it is not easy to promote. The raspberry ketone derivative and the aforementioned gram fly mainly undergo a hydrolysis process (the hydrolysis of the raspberry ketone derivative to produce formic acid and raspberry ketone, and the fly is hydrolyzed to produce acetic acid and raspberry ketone) to simultaneously volatilize and release the raspberry ketone, thereby Long-distance lure effect. However, if the hydrolysis rate is too fast, crystallization will not be formed. If the raspberry ketone crystals are formed on the carrier (the crystal is not equal to the complete decomposition of the raspberry ketone derivative, but the phenomenon of supersaturation after decomposition, ie, the decomposition of raspberry ketone If the amount is not saturated, it will not crystallize when dissolved in a raspberry derivative or other solvent, and the relative long-range attracting efficacy is lost.

Example 1 Relationship between moisture and decomposition rate of raspberry ketone derivatives

After adding different amounts of pure water to the quantitative raspberry ketone derivative, the content was determined by high performance liquid chromatography (HPLC) after standing at room temperature for 7 days. Figure 1 shows the rate of hydrolysis of raspberry ketone derivatives and the rate of formation of raspberry ketone. The higher the amount of water added, the higher the decomposition rate of the raspberry ketone derivative and the higher the amount of raspberry ketone. Therefore, it is known that hydrolysis is The reason why the raspberry ketone derivative is mainly decomposed and crystallized into raspberry ketone. The analysis of moisture is a Karl Fischer moisture titrator.

Example 2 Decomposition rate of raspberry ketone derivatives at different compounding concentrations

When polyethylene glycol (PEG) was used as a solvent control (Fig. 2), the raspberry ketone derivatives of different concentrations were analyzed by HPLC for one week after opening to calculate the decomposition rate, and the decomposition rate was obtained. Both are more than 45%, and crystals will form after one week.

If castor oil is used as a solvent (mixing raspberry derivatives with castor oil in a container and then uniformly mixing with ultrasonic waves for 15 minutes), it can significantly delay the decomposition rate of raspberry derivatives and delay The time at which crystallization occurs. In this formulation, the more the castor oil is added, the slower the decomposition rate of the raspberry ketone derivative is, and there is no crystallization in the bottle or in the carrier. This material can also be used for field attraction (Fig. 3). . One week after opening the bottle, it is derived from raspberry ketone. When the concentration is 50 and 30%, the hydrolysis rate will drop below 40%, and the crystallization will be significantly better after the second week than the unrefueled 100% and 85% (the hydrolysis rate is greater than 50%). At 5 and 10% raspberry ketone derivative concentration, the hydrolysis rate is less than 20%, although the content will continue to decrease, but raspberry ketone is soluble in the formula and will not crystallize until the 8th week. A decoy experiment was performed.

Example 3 Net cage induction efficiency of raspberry ketone derivatives at different blending concentrations

4 μl of 100, 50, 10 and 5% raspberry derivatives, and 2 μl of 100% raspberry derivative (half the amount) for close-range inducing tests, cage test at 40 x 20 x 16 cm ^{In the} cage, 20 males of 1, 5, 10 and 20 days old were placed in the cage, and water and artificial feed were given at the same time. The inducer is a plastic cup with a capacity of 250 ml. In the 1/3 and 2/3 heights of the cup wall, 0.7 ml microcentrifuge tubes are inserted upside down in three directions of the circumference of the circumference, and the tip is cut open to a width of 0.3 cm. The lid of the cup hangs a circular cotton piece with a diameter of 0.6 cm in the center with a cotton thread. During the experiment, 4 μl of flies or raspberry ketone derivatives were added to the cotton pads, and the inducer and the lid were combined and placed in the center of the cage to record the number of males trapped within 72 hours, and each treatment was repeated 5 times.

The results showed that the 50% raspberry ketone derivative had a higher extraction rate than the 100% raspberry derivative and half of the 100% raspberry derivative (Fig. 4). Therefore, the 50% formulation concentration has a good effect; while the 10 and 5% raspberry ketone derivatives have a slightly less attractive effect than the 100% raspberry derivative, but there is no significant difference. The use of different concentrations of raspberry ketone derivatives at close range does not have a significant negative impact on males and has the potential to increase the rate of attraction at 50% concentration. Further testing over long distances is needed to compare the differences.

Example 4 Field Inducing Test

Phytophthora attractants (such as raspberry ketone, flies and raspberry derivatives), castor oil and insecticide 5% (malathion, fipronil or spinosad) 5 mL of the mixture is adsorbed on the adsorbent porous material (cane board, non-woven fabric, foam and cotton sheet, etc.), and placed in a modified fly trap, such as a modified Mai's trap, every 20 meters in the shade. Hang one at a height of 1-1.5 meters, and cover it in the field. After 5 weeks, count the number of insects in the fruit fly. However, if the trapping device (such as the trap) is not allowed to escape, it is not necessary to add an insecticide.

As shown in Figure 5, when the raspberry ketone derivative is used in the field, its attracting effect is better than that of the currently used flies (CL), and when the raspberry ketone derivative is formulated to 50% concentration, its attracting effect and 100%. The raspberry ketone derivative is equivalent and superior to the currently used gram fly. If it is formulated to a concentration of 10%, its attracting effect is slightly better than 100% raspberry ketone derivative; while castor oil (oil) and its decomposition products are used alone. When raspberry ketone (dissolved in castor oil), its attracting effect is not good.

Example 5 Field Inducing Different Fly Tests

In the field, the experiment was carried out with castor oil formula to mix different concentrations of flies. The experiment was carried out by cultivating melons and fruit flies for every 20 meters. The maiden traps were repeated four times every 20 meters, containing 5% of the promises and different proportions of attractants. 5 mL was adsorbed on cotton sheets and the number of induced insects was counted every seven days. The results are shown in Figure 6. The number of insects in the different proportions of the flies solution was comparable to that of the unmixed flies (the standard deviation of the 100% flies group was 29 and 25). And count the number of melons and fruit flies in each attractant, there are more than three kinds (Figure 7), among which the number of fruit fly and pumpkin fruit fly is a large proportion, and the fruit flies account for 50-75%, pumpkin fruit fly 20-50%.
