Description

Carnivorous bee attractant

The present invention relates to a carnivorous bee attractant and a method for attracting carnivorous bees. More specifically, the present invention relates to an invention characterized by using molasses as an attracting component.

Various types of pest traps have been known for a long time. For example, pest attracting traps for small flying pests such as cockroaches and flies are widely used in general households, restaurants, factories, and the like. There is.
Further, as a bee catcher, various shapes have been proposed. Specifically, Patent Document 1 describes a trap in which an attracting capture composition for attracting bees is stored inside a cup-shaped container, and a lid having a bee entrance is attached to the upper part of the container. There is. Patent Document 2 describes that a bee entrance is arranged in the center of the upper part of the trap in order to prevent the bee once captured from escaping from the trap. Further, Patent Document 3 describes that by using a bee attractant having a specific sugar concentration, a fermented odor due to putrefaction is generated and the capture efficiency is improved.

Since hornets prey on beekeeping honeybees, extermination of hornets is important for the beekeeping industry. However, conventionally known bee traps have a problem that, in addition to the wasps and paper wasps to be captured, honeybees that are beneficial to humans that do not harm humans are also captured. In addition to poisonous bait that selectively controls only carnivorous bees, it is desired to provide bee catchers and catching methods, but no reports have been made yet.

The object of the present invention is to selectively control only carnivorous bees.

As a result of intensive research to solve the above problems, the present inventor has found that molasses attracts only carnivorous bees, and uses a selective carnivorous bee attractant containing molasses as an attracting component. It has led to the solution of the problem.

Specifically, the gist of the present invention is as follows.
1. 1. A carnivorous bee attractant containing molasses.
2. 2. A method of attracting carnivorous bees using a composition containing molasses.
3.1. A carnivorous bee poison bait containing the carnivorous bee attractant described in 1.

The carnivorous bee attractant of the present invention can selectively attract only carnivorous bees such as wasps and paper wasps.
Further, the carnivorous bee attractant of the present invention can be used as a carnivorous bee poison bait that can surely control the attracted bees by combining with a known insecticide, and an efficient control effect on the bees can be easily achieved. Obtainable.

It is an exploded perspective view of the structure which excluded the liquid absorbing member from the specific aspect of the bee poison bait container which stores the carnivorous bee poison bait using the carnivorous bee attractant of this invention. It is a perspective view which shows the state which the inner lid and the umbrella of the bee poison bait container shown in FIG. 1 are removed.

Hereinafter, the carnivorous bee attractant of the present invention and the method for attracting carnivorous bees will be described in detail.
The carnivorous bee attractant of the present invention contains molasses as an attractant component.
<Molasses>
Molasses is a by-product of sugar production and has a high specific gravity (about 1) that remains after boiling sugar cane or sugar beet juice, crystallizing the sugar, and then centrifuging to separate the crystallized sugar. It is a sticky black-brown liquid containing a large amount of components other than sugar (about .4). The sugar content in molasses is generally about 40 to 50%, and is used as a raw material for the fermentation industry and feed for livestock.
Molasses contains furfuryl alcohol, furfural, sotolon and the like, which are aroma components.
Until now, no specific studies have been conducted on attractants that use molasses as an attractant for bees, and bee traps and bee poison bait agents that use them.
The present inventor has completed the present invention by finding that molasses is excellent as an attractant component for carnivorous bees while examining various bee-attracting components.
By using the molasses of the present invention as an attracting component, only carnivorous bees such as wasps and paper wasps can be selectively attracted, which is very useful.
The molasses of the present invention contains, for example, about 62 g of carbohydrate, about 7 g of ash, about 3 g of protein, about 0.1 g of lipid, about 25 mg of sodium, about 27 g of water in 100 g of molasses, and has a sugar content (Brix value). A commercially available product having a molasses of 77 ± 3 and a dark brown viscous liquid substance can be used. Moreover, brown sugar containing molasses can also be used.

The carnivorous bee attractant of the present invention contains molasses, and it is preferable to set the sugar content (Brix) of the attractant in the range of 40 or more and less than 83 because the eating property of the bee is enhanced. Bees have a habit of returning home after eating food and feeding other bees in the nest by mouth. Therefore, when the carnivorous bee attractant and the insecticide of the present invention are used in combination as a carnivorous bee poison bait, the transport of this carnivorous bee poison bait to the beehive can be promoted. It is useful because it exerts a high extermination effect on bees and can efficiently destroy the entire beehive.
Further, when the sugar content (Brix) of the carnivorous bee attractant of the present invention is 40 or more, mold and the like are generated even when the carrier having a large contact with air is impregnated, adhered or coated with the attractant. Since it is greatly reduced and the putrefaction of the attractant is suppressed, the effect that the extermination effect on the bee does not decrease can be obtained.
Further, when the carnivorous bee attractant and the insecticide of the present invention are used in combination as a carnivorous bee poison bait, the sugar content (Brix) of the poison bait is set to the range of 40 or more and less than 83, and 1 meter from the beehive. By placing it further away and within 3 meters of the bee's line of motion, the bees will recognize the poison bait as a new bait or new feeding ground at an early stage, resulting in an entire beehive. It is preferable because it can be disintegrated early.

When the sugar content (Brix) of the carnivorous bee attractant of the present invention is in the range of 40 or more and less than 83, the sugar content (Brix) is the reading of a refractometer for sugar at 20 ° C., and is used for bee extermination. It means a value measured at 20 ° C. using a digital refractometer PAL-1 (manufactured by Atago Co., Ltd.) for the entire attractant of. Since the measurement range of the digital refractometer PAL-1 (manufactured by Atago) is 0.0 to 53.0 (Brix), if the sugar content (Brix) is higher than 53.0, use ion-exchanged water 10 times. It is diluted and measured, and the value is converted to a value 10 times. In the case of a non-liquid preparation, the sugar content is measured by diluting it 10 times with ion-exchanged water and multiplying the measured value by 10 times.
The sugar content (Brix) of the carnivorous bee attractant of the present invention is preferably 40 or more, more preferably 50 or more, and even more preferably 60 or more. The upper limit of the sugar content (Brix) is preferably less than 83.
When the sugar content (Brix) of the carnivorous bee attractant of the present invention is in the range of 40 or more and less than 83, not only the eating habitability of the bee is improved, but also an insecticide is used in combination as a carnivorous bee poison bait. In, bees can be encouraged to carry their pesticides to their nests. As a result, the transported poison bait is given to other bees in the nest, and the poison bait spreads throughout the nest, exhibiting an excellent extermination effect in which the nest collapses. That is, by attracting the bees from the nest to the poison bait and bringing the poison bait back into the nest, the entire nest can be finally destroyed, which is useful.

When the carnivorous bee attractant and the insecticide of the present invention are used in combination as a carnivorous bee poison bait, the sugar content (Brix) of the poison bait should be in the range of 40 or more and less than 83, and the distance from the beehive should be more than 1 meter. And, by arranging it within 3 meters from the bee's movement line, the bee recognizes the poison bait as a new bait or a new feeding ground at an early stage, and as a result, the entire beehive collapses early. It is preferable because it can be caused. This suitable arrangement is that if the poison bait is placed within 1 meter from the beehive, the bees will be alert and difficult to approach the newly emerging artificial poison bait, and more than 3 meters from the bee's flow line. If the poison bait is placed in a remote place, it is considered that it takes a very long time for the bees to recognize the poison bait as a new bait or a new feeding ground.
That is, when the carnivorous bee attractant of the present invention and the pesticide are used in combination as a poison bait, the sugar content (Brix) of the poison bait is set in the range of 40 or more and less than 83, and the distance from the beehive is more than 1 meter. In addition, by arranging the bees within 3 meters from the movement line of the bees, the bees reach the poison bait early and the transport of the poison bait to the nest is promoted, and as a result, the entire beehive is early. I presume that it will collapse.
The "traffic line of a bee" in the present invention means a trajectory in which a bee moves back and forth between the nest and a conventional feeding ground starting from the beehive.

<About carnivorous bee poison bait>
The carnivorous bee attractant of the present invention can be used as a carnivorous bee poison bait in combination with a known insecticide. For example, if an eating base impregnated with, adhered to, or coated with this poison bait is installed at a place where carnivorous bees are exterminated, an insecticidal effect can be obtained by eating by carnivorous bees. Examples of the material of the eating substrate include sponge, absorbent cotton, natural fiber, non-woven fabric of synthetic fiber, polymer such as water-absorbent polymer, woven cloth, paper, and porous body.
This carnivorous bee poison bait is preferably used by being stored in a container, and the shape, size, etc. of the container to be stored are limited as long as the carnivorous bee attractant of the present invention can be stored inside. However, the form may be suitable for the place of use and the method of use. The material of this container is, for example, glass, metal, plastic, etc., as well as special paper having a waterproof and water-repellent function that prevents the carnivorous bee attractant of the present invention from leaking from the container. Not limited. When the carnivorous bee poison bait of the present invention is installed outdoors, a space is provided with respect to the opening in order to prevent rainwater or the like from infiltrating and diluting the poison bait in the present invention and reducing the carnivorous bee control effect. It is preferable to have a covering portion for preventing the ingress of rainwater and the like. The container of the carnivorous bee poison bait containing the carnivorous bee attractant of the present invention should be placed in a flat place where it is not exposed to direct sunlight, hung from the ground about 1 to 3 m, or the entrance of the container is not blocked. It is preferable to use it.

<Specific example of bee poison bait container>
The configuration of the bee poison bait container 1 suitable for storing the carnivorous bee poison bait using the carnivorous bee attractant of the present invention will be described with reference to FIGS. 1 and 2. The bee poison bait container 1 is designed so that bees can easily invade, and at the same time, it is difficult for human fingers to touch the poison bait using the carnivorous bee attractant of the present invention, and the effective period of the bee poison bait can be extended. It was configured in.
The bee poison bait container 1 includes a lower container 10 (container body: bottom surface 101, side surface 102, protrusion 103, opening 105), an inner lid 20, an umbrella 30, and a liquid absorbing member 40.

The inner lid 20 is configured to be engaged with the outside of the lower container 10 and to be fixed to the lower container 10. A bee entrance 21 (opening) communicating with the lower container 10 is formed in the center of the inner lid 20. Further, the inner lid 20 is formed with a bee retention port 22 for the bees to anchor. The bee-retaining port 22 is inclined so that the inside is higher than the outer edge thereof (the height is increased from the outer edge of the bee-retaining port 22 toward the center side). Bees may be described as having a negative runnability, that is, the property of organisms traveling in the opposite direction of gravity. By providing the inclined surface 22A (distance D4 from the outer edge to the bee entrance / exit 21), it becomes possible to promote walking of the bee into the bee poison bait container 1. As shown in FIG. 1, a groove G extending in the radial direction may be provided between the adjacent inclined surfaces 22A. The groove G allows the bee to hook the leg, thus assisting the bee to climb the inclined surface 22A. The inclined surface 22A may be provided with a convex portion or an uneven portion.

By providing the inclined surface 22A, when a human finger is inserted through the gap between the umbrella 30 and the inner lid 20, the inserted finger comes into contact with the inclined surface 22A and is guided obliquely upward. Therefore, it is possible to guide the finger in the direction away from the liquid absorbing member 40 housed in the lower part of the lower container 10. Further, even if the joint of the finger is to be bent, the finger hits the umbrella 30 and becomes difficult to bend, so that it becomes difficult to touch the liquid absorbing member 40.
Further, by providing the inclined surface 22A, the wind passing through the bee poison bait container 1 is guided upward along the inclined surface 22A. Therefore, it is possible to suppress the wind from directly hitting the liquid absorbing member 40, and it is possible to suppress the fluctuation of the volatilization amount of the poison bait agent using the carnivorous bee attractant impregnated in the liquid absorbing member 40. As a result, it becomes possible to suppress fluctuations in the usable period of the liquid absorbing member 40.
Further, the bee retention port 22 is formed so as to project radially outward from the outer peripheral surface of the lower container 10. By providing the bee retention port 22 so as to project in this way, the bees can be easily anchored, and the bees can enter the inside of the lower container 10 through the bee entrance / exit 21 formed in the center of the inner lid 20.
A plurality of engaging hole portions 23 for engaging the lower end of the umbrella 30 (lower end of the side wall portion 32) are formed in the peripheral portion of the inner lid 20.

The umbrella 30 is engaged with the inner lid 20 so as to cover the upper part of the bee doorway 21. When the umbrella 30 is engaged with the inner lid 20, the liquid absorbing member 40 exposed to the outside through the bee entrance / exit 21 is covered from above by the umbrella 30, and water or the like (for example, rain) is applied to the liquid absorbing member 40 from the outside. ) Can be suppressed from hitting directly. Further, the inclined surface 22A of the inner lid 20 described above can also prevent water or the like from entering the lower container 10. The umbrella 30 is provided with an arch-shaped opening 31 that communicates the bee entrance 21 and the outside of the bee poison bait container 1. The bees anchored at the bee retention port 22 can enter the inside of the bee poison bait container 1 (inside the umbrella 30) through the arch-shaped opening 31, and further enter the inside of the lower container 10 through the bee entrance 21. The side wall portions 32 located on both sides of the arch-shaped opening 31 engage with the inner lid 20, and the umbrella 30 and the inner lid 20 are fixed. Here, the height of the arch-shaped opening 31 with respect to the inclined surface 22A of the inner lid 20 (the vertical distance between the inclined surface 22A and the intermediate portion of the arch-shaped opening 31) is 10 mm or more and 35 mm or less. It is preferably present, and more preferably 10 mm or more and 30 mm or less. When the height of the arch-shaped opening 31 from the inner lid 20 is 10 mm or more, even a large bee such as a wasp can invade the bee poison bait container 1. On the other hand, if the height of the inner lid 20 and the arched opening is larger than 35 mm, the human finger tends to come into contact with the carnivorous bee poison bait using the carnivorous bee attractant of the present invention. In addition, large insects other than bees invade.
In addition, on the upper surface of the umbrella 30, a hooking portion 35 for hooking and arranging the bee poison bait container 1 on an external member is provided.

The liquid-absorbent member 40 is an impregnated body impregnated with a poison bait agent using the carnivorous bee attractant of the present invention for feeding bees.
As shown in FIG. 2, the liquid absorbing member 40 is formed with a hole 42 (recess) extending in the direction from the upper surface 40a side of the main body portion (liquid absorbing member main body) toward the lower surface. The hole 42 is not limited to the embodiment formed only in the liquid absorbing member 40, and may be formed between the liquid absorbing member 40 and the lower container 10, for example, or is formed only in the lower container 10. You may. When the hole 42 is formed only in the lower container 10, if the hole 42 is formed along the peripheral edge of the liquid absorbing member 40, the bee that has entered the inside of the hole 42 impregnates the liquid absorbing member 40. It is suitable because it is possible to eat a poison bait agent using the carnivorous bee attractant of the present invention.

The hole 42 has an opening shape for a bee to enter the inside thereof, in other words, an opening for the bee's head to enter inside. Specifically, the diameter of the hole 42 is preferably in the range of 5 to 30 mm. If the diameter of the hole 42 is larger than 30 mm, the inside of the hole 42 tends to dry, and if the diameter of the hole 42 is smaller than 5 mm, it becomes difficult for the bee head to enter the inside of the hole 42. Bees have a habit of poking their necks into their burrows (for example, wasps and paper wasps poke their heads into their burrows to get nutrients from the larvae in their burrows (thick liquid collects below the burrow 42). In this case, hornets and paper wasps have a habit of sticking their heads and licking the liquid below the hole 42), so this habit is used to use the carnivorous bee attractant of the present invention contained inside the hole 42. The bee eats the poisonous bait. Therefore, even if the upper surface 40a side of the liquid-absorbent member 40 is dried, the carnivorous system of the present invention is held inside the hole 42 formed in the liquid-absorbent member 40 by utilizing the habit of such a bee. Since the bees eat the poison bait using the bee attractant, the effective period of the poison bait can be extended.
The hole 42 is formed so as to extend from the upper surface 40a side to the lower surface side of the liquid absorbing member 40, and the extending direction thereof includes an arbitrary direction.
Further, the hole 42 does not have to penetrate the liquid absorbing member 40 as long as it has an opening sufficient for the bee's head to enter. For example, a poison bait agent using the carnivorous bee attractant of the present invention contained in the lower surface side which is hard to dry as compared with the upper surface 40a side which is relatively easy to dry when the thickness of the liquid absorbing member 40 is more than half. It is suitable because the bee can eat it.
Although the specific embodiment of the bee poison bait container 1 has been described above with reference to FIGS. 1 and 2, the size, shape, arrangement, number, etc. are not limited to this, and may be appropriately changed according to the purpose. it can.

<About bee traps>
The carnivorous bee attractant of the present invention may be stored in a container and used as a bee trap.
The shape and size of the container to be stored are not limited as long as the carnivorous bee attractant of the present invention can be stored inside, and the container may be in a form suitable for the place of use and the method of use. The material of this container is, for example, glass, metal, plastic, etc., as well as special paper having a waterproof and water-repellent function that prevents the carnivorous bee attractant of the present invention from leaking from the container. Not limited.
As an example of the aspect of the container, it is preferable to have a lid covering the opening of the container, and an opening through which a bee can enter is formed in either the lid or the container. The opening may have a size and shape that allows bees to easily enter the container, and the dimensions (diameter, width, length) of the opening are preferably set to 20 mm or more and 35 mm or less, and 25 mm or more and 30 mm. It is more preferable to set as follows. If the opening is smaller than 20 mm, it is difficult for large bees such as the giant hornet to invade through the opening, and the capture efficiency is lowered. If the opening is larger than 35 mm, butterflies, moths, beetles, etc. other than bees will invade the container. It is preferable to form a plurality of openings in the container so that the bees can easily enter the container, but the number of openings may be 2 or more and 5 or less depending on the size of the container. preferable.
The container may be a transparent or translucent window-equivalent container so that the number of bees captured can be visually observed, or a transparent or translucent container, which makes the captured bees difficult to see and suppresses discomfort. it can.
Further, in order to prevent the bees that have entered the container from easily escaping to the outside of the container, the opening is preferably funnel-shaped or the like.
When the bee catcher is installed outdoors, a space is provided for the opening in order to prevent rainwater or the like from infiltrating and diluting the carnivorous bee attractant of the present invention and reducing the bee catching efficiency. It is preferable to provide a covering portion for preventing the ingress of rainwater or the like.
The bee catcher using the carnivorous bee attractant of the present invention should be kept out of direct sunlight as much as possible, hung from the ground about 1 to 3 m, fixed to a fence or the like, or flat so that the entrance of the container is not blocked. It is preferable to place it in a suitable place for use.

Hereinafter, the present invention will be described in more detail with reference to test sample preparation examples, test examples, and the like, but the present invention is not limited to these examples.
In the examples, unless otherwise specified, parts mean parts by weight.

<Confirmation test 1 for carnivorous bee attraction effect>
The following tests were conducted to confirm that the carnivorous bee attractant of the present invention exhibits an eating-attracting effect on carnivorous bees.
(1) Preparation of test sample A test sample containing 24% by weight of molasses was prepared from molasses, attracting components (sugar, lactic acid bacteria beverage, etc.) and water.
As a comparative test sample, 80% by weight honey water was prepared.
(2) Test method A non-woven fabric (cylindrical shape having a diameter of 50 mm and a thickness of 10 mm) was impregnated with 25 g of a test sample or a comparative test sample. Two types of these, each placed on a KP cup (diameter 130 mm × height 100 mm), were prepared. One adult honeybee ♀ or three adults honeybee ♀ were placed therein and observed for 30 minutes, and the average value of the contact time (seconds) with the sample was measured. The "contact time with the sample (seconds)" means the time (seconds) in which the honeybee or the honeybee is on the non-woven fabric impregnated with the test sample or the comparative test sample.
Table 1 below shows the average value of the contact time (seconds) of the honeybee and the honeybee to the test sample or the comparative test sample.

As shown in Table 1, it was confirmed that the test sample containing molasses exerts the same attractive effect on the carnivorous bee, Kiirosuzumebachi, as the comparative test sample composed of 80% by weight honey water. On the other hand, it was confirmed that honeybees prefer to eat comparative test specimens composed of 80% by weight honey water rather than test specimens containing molasses. Furthermore, it was also clarified that the carnivorous bee, Kiirosuzumebachi, had an extremely short contact time of 110 seconds with a test sample containing molasses, whereas the honeybee had an extremely short contact time of 3 seconds. Kiirosuzumebachi always ate while in contact with the test specimens or comparative test specimens. On the other hand, the honeybees came into contact with the test sample, but the behavior of immediately leaving the test sample was visually confirmed.
From this result, it was clarified that molasses exerts a "selective attracting effect" on carnivorous bees.

<Carnivorous bee attraction effect confirmation test 2>
Using the carnivorous bee attractant of the present invention, an outdoor test was conducted to confirm the attracting effect on the carnivorous bee.
(1) Preparation of test sample As shown in Table 2 below, with molasses, attractant components (liquor, vinegar, lactic acid bacteria beverage, etc.), solvent (ethyl lactate), surfactant (polyglyceryl monolaurate), sodium chloride and water. , Example test samples (Examples 1 to 4) were prepared. In addition, a comparative example test sample (Comparative Example 1) containing no molasses was prepared in the same manner as the example test sample. The compositions of the Example test samples of Examples 1 to 4 and the Comparative Example test samples of Comparative Example 1 are summarized in Table 2 below. The numerical values in Table 2 mean% by weight.

(2) Test method In a wooded area in Ako City (test areas 1 and 2), a commercially available bee trap was used to place each of the example test samples of Examples 1 to 4 and the comparative example test sample of Comparative Example 1 in a commercially available bee trap. The ones stored in the empty containers (plastic, diameter 90 mm, height 120 mm) were placed 5 m apart from each other and installed at a height of 2 m from the ground, and the cumulative number of carnivorous bees caught was 2 weeks (May 2019-). It was observed over (June).
Table 3 shows the number of carnivorous bees captured in Examples 1 to 4 and Comparative Example 1 in Test Groups 1 and 2, and Table 4 shows the types of carnivorous bees captured in Examples 1 to 4.

As shown in Tables 3 and 4, the bee trap (Comparative Example 1) that stores the bee attractant that does not contain molasses could not catch the bees at all, but stores the carnivorous bee attractant that contains molasses. It was confirmed that the bee traps (Examples 1 to 4) that catch a large number of bees and have a very excellent bee attracting effect.
From the results shown in Table 4, it was clarified that the bee trap containing the carnivorous bee attractant containing molasses of the present invention can control not only a specific type of wasp but also a wide variety of wasps. In particular, a high attracting effect was observed on the highly aggressive giant hornet, and it was confirmed that the carnivorous bee attractant of the present invention is extremely useful.

<Carnivorous bee attraction effect confirmation test 3>
Using the carnivorous bee attractant of the present invention, in order to confirm the attracting effect on the carnivorous bee, an outdoor test was conducted at different test times from the above-mentioned "Carnivorous bee attracting effect confirmation test 2".
(1) Preparation of test sample As shown in Table 5 below, with molasses, attractant components (liquor, vinegar, lactic acid bacteria beverage, etc.), solvent (ethyl lactate), surfactant (polyglyceryl monolaurate), sodium chloride and water. , Example test samples (Examples 5 and 6) were prepared. In addition, a comparative example test sample (Comparative Example 2) containing no molasses was prepared in the same manner as the example test sample. The compositions of the Example test samples of Examples 5 and 6 and the Comparative Example test samples of Comparative Example 2 are summarized in Table 5 below. The numerical values in Table 5 mean% by weight.

(2) Test method In a wooded area in Ako City (test areas 3 and 4), the test specimens of Examples 5 and 6 and the Comparative Example Test Specimen of Comparative Example 2 were placed in a commercially available bee trap. The items stored in the empty containers (plastic, diameter 90 mm, height 120 mm) were placed 5 m apart from each other and installed at a height of 2 m from the ground, and the cumulative number of carnivorous bees caught was 2 weeks (from June 2020). It was observed over (July).
Table 6 shows the number of carnivorous bees captured in Examples 5 and 6 and Comparative Example 2 in Test Groups 3 and 4, and Table 7 shows the types of carnivorous bees captured in Examples 5 and 6.

As shown in Tables 6 and 7, the bee trap (Comparative Example 2) that stores the bee attractant that does not contain molasses could not catch the bees at all, but stores the carnivorous bee attractant that contains molasses. It was confirmed that the bee traps (Examples 5 and 6) that catch a large number of bees and have a very excellent bee attracting effect. In Example 5, 30% by weight of the 41% by weight of the known attractant component of Comparative Example 2 such as liquor, vinegar, and lactic acid bacteria beverage was replaced with molasses, but the molasses was compared with the known attractant. It was revealed that it is extremely efficient and has an excellent bee-attracting effect.
Further, from the results shown in Table 7, it was clarified that the bee trap for storing the carnivorous bee attractant containing molasses of the present invention can control not only a specific type of wasp but also a wide variety of wasps. ..

The carnivorous bee attractant of the present invention exerts an eating-attracting effect only on highly aggressive carnivorous bees such as wasps and paper wasps, and can selectively attract carnivorous bees, which is extremely useful.
Further, the carnivorous bee attractant of the present invention can be used as a carnivorous bee poison bait that can surely control the attracted bees by combining with a known insecticide, and an efficient control effect on the bees can be easily achieved. Can be obtained and is useful.
