Bait device

The invention relates to a gel bait device for attracting mosquitoes to lay eggs and then killing them, in particular to an insecticidal bait device for controlling the gel bait to gradually crack from the surface to prolong the use effect and increase the number of trapped mosquitoes.

Agricultural food crops and horticultural crops are often endangered by various fruit flies (Fruit flies, Trypetidae), fruit flies (Drosophilidae Drosophilidae), and flies (Phorid flies, phoridae). It is still an important pest on crops. The government spends huge sums of money every year to promote and subsidize farmers to use the comprehensive prevention and control method to reduce the damage degree of fruit flies and claw flies. However, it still fails to obtain satisfactory results, that is, the control effect is not good.

In the non-agricultural field, in the daily life environment of human beings, because of urban neighborhoods, collective houses, buildings, apartments, etc., the office buildings or residential buildings for work are rented or occupied in layers, when a household If you buy fruit, if the food waste after peeling off the peel is not sealed with a plastic bag immediately, it will induce many flies or flies to fly into your home or office, and fly back and forth in front of you, except that it is difficult to drive it away by hand. Even the use of insecticides is hard to drive, and it has become a "interfering pest" in the category of modern environmental sanitation pests.

In order to prevent fruit flies and flies, pest control experts have tried to use different insecticidal products such as spray insecticides, water-steamed insecticides, mosquito coils, liquid mosquito coils, etc., but found that they are not effective in preventing the invasion of fruit flies and flies. Can't drive it away. The only product that works immediately is the use of bait, which uses the habits of fruit flies or scorpions to ripen or even rot fruits or peels to make jelly or gel. The base agent is mixed with various proportions of fruit vinegar, wine, water, sugar, etc. in the base, and a small amount of repellent insecticide is added to make the bait. When fruit flies or flies are exposed to the aroma of the bait, they are attracted to fly into the bait box to suck and lay eggs. At this point, they will come into contact with pesticides or eat insecticides, causing fruit flies or flies. Will die in the bait box or near the bait box.

Referring to Fig. 1, the lure bait box 10 is mainly placed directly inside the whole block bait 11 and relies only on the upper surface area of the block bait 11 as a volatilization route for attracting the bait. The design of the flies attracting bait box 10 is obvious in the first to fifth days after tearing off the aluminum foil (or pvc film) of the sealed bait, which can trap many fruit flies and flies, but since the 6th day By the 30th day, the surface of the jelly or gel is hardened by the evaporation of moisture, which hinders the volatilization of the attracting components inside the jelly or the gel bait, thereby reducing the trapping effect.

Referring to Fig. 2, another lure pack 10 is used to cut the jelly bait into a small square bait 12 to avoid surface hardening problems, so that the internal attracting components of the jelly or gel bait are fully in contact with the air. And volatilize as soon as possible. However, this design cuts a single large piece of jelly bait into a plurality of small square bait 12, which causes the surface area of air contact to increase several times, and the evaporation rate is greatly increased, of course, the attracting effect is naturally better. However, the preferred attracting effect of the lure trap 10 can only be maintained on the 1st to 7th days. After the 8th day, most of the active ingredients have rapidly evaporated and the subsequent entrapment effect is immediately reduced.

Therefore, at present, all commercially available fruit fly attractants are faced with the problem that the maintenance period cannot exceed one month (marking period). In fact, the effect can be significantly reduced after only 7 to 10 days, which will cause consumers to This product loses trust and reduces the willingness to use it. In view of this, it is necessary to design a bait device with a slow release attractant to improve the current deficiencies.

The main object of the present invention is to provide a bait device which can automatically and gradually crack into the depth of the bait during the evapotranspiration process of the gel bait without the external force (electric power, heat), and achieve the automatic slow release attracting component. Effectively extend the life of the bait device.

A secondary object of the present invention is to penetrate the gel bait by designing a breaking device, so that the gel bait generates a broken incision, and the gel bait is automatically pulled from the top to the bottom by the tension between the surface tension and the cohesive force at the incision position.

Another object of the present invention is to design a cutting protrusion of different lengths, different numbers, different positions and different shapes, which can effectively control the time when the surface of the gel bait leaves the cutting post and generate cracks of different shapes and depths. Thereby controlling the amount and speed of release of the active ingredient inside the gel bait.

Another object of the present invention is to design a longest cutting stud as a criterion for determining the failure of the bait. When the upper surface of the gel bait completely leaves the cutting stud, the effective attracting components of the gel bait are volatilized. Upon completion, a new bait device must be replaced.

In order to achieve the above object, the bait device of the present invention, in a first preferred embodiment, comprises: a container having an opening and extending downwardly from the opening to form a basin having a chamber, the top periphery of the basin Extending outwardly to form a cap edge; a container cover assembled on the top of the container and having a plurality of venting holes, and the inner edge of the hem of the container cover has a plurality of cassettes assembled and fixed with the container; a safety cover And the pot body of the container is assembled, and is located at the top of the chamber, has a gas permeable area formed by a plurality of through holes; a breaking device is disposed between the safety cover and the container, and has a plurality of cutting studs; A gel bait is installed inside the chamber of the basin, and is penetrated by the cutting protrusion to form a plurality of broken slits for increasing the volatile area.

For a more detailed and detailed understanding and understanding of the structure, the use and the features of the present invention, the preferred embodiments are described in detail with reference to the drawings as follows: First, please refer to Figure 3 and 4, in the first preferred embodiment, the bait apparatus of the present invention is mainly composed of a container 20, a container lid 30, a safety cover 40, a destruction device 50, and a gel bait 60. The container 20 has an opening 21 and extends downwardly from the opening 21 to form a basin 23 having a chamber 22, and the inside of the basin 23 has a plurality of positioning posts 24 extending toward the opening 21, and is located above The peripheral edge of the tip end of the basin 23 extends outward to form a cap edge 25.

The container cover 30 has a plurality of venting holes 31, and a plurality of latches 32 assembled and fixed to the cap edges 25 are provided on the inner edge of the hem, so that the container cap 30 is positioned above the container 20. And on The safety cover 40 is located at the top of the chamber 22 and has a plurality of positioning holes 41 corresponding to the positioning posts 24. The surface of the safety cover 40 is provided with a chamber 22 of the container 20 and the container. In the preferred embodiment, the gas permeable region 42 of the cover 30 is formed by a plurality of through holes 421.

The breaking device 50 has a plurality of cutting protrusions 51 disposed on the bottom surface of the safety cover 40 between the safety cover 40 and the container 20, and the gel bait 60 is installed in the chamber 22 of the basin 23. Internally, the cutting projection 51 of the breaking device 50 is inserted from the top to the bottom to form a plurality of breaking slits 61 for increasing the volatile area, so that the active component of the gel bait 60 is gradually released through the breaking slit 61. However, the gel bait 60 may be one of a jelly-like material or a paste-like material.

Referring to FIGS. 4 and 5, the plurality of cutting studs 51 have the same length and are symmetrically arranged with respect to the safety cover 40, and the vertical between the bottom of the chamber 22 and the opening 21 is vertical. The height exceeds the length of the plurality of cutting studs 51 described above. However, the lengths of the plurality of cutting ribs 51 are set to be equal length, and the combination of the symmetrical arrangement with respect to the safety cover 40 is only for convenience of explanation, and the shape of the cutting ram 51 is not limited. That is, the above-mentioned cutting studs 51 may exhibit an irregular arrangement with respect to the above-mentioned safety cover 40 as shown in FIG. 6A or different lengths as shown in FIG. 6B.

Thereby, the criterion for determining the failure of the gel bait 60 is completed through the longest cutting protrusion 51. When the top surface of the gel bait 60 completely leaves the cutting protrusion 51, the gel bait 60 is effectively induced. The ingredients are all volatilized and the new bait device of the present invention must be replaced.

Referring to FIG. 7, in a second preferred embodiment, the difference from the first preferred embodiment is that the plurality of cutting studs 51 are distributed on the bottom surface of the safety cover 40 and the bottom of the chamber 22. The top surface of the basin 23 allows the cutting stud 51 located at the bottom of the chamber 22 to penetrate the gel bait 60 from the bottom to the top. The assembly state between the container 20, the container cover 30, the safety cover 40 and the gel bait 60 is the same as the first preferred embodiment, and details are not described herein.

However, the plurality of cutting protrusions 51 are distributed on the bottom surface of the safety cover 40 and the top surface of the basin 23 at the bottom of the chamber 22, so that the upper and lower surfaces of the gel bait 60 are penetrated by the plurality of cutting protrusions 51, which is effective. The time at which the surface of the gel bait 60 is separated from the cutting stud 51 is controlled, and the above-described breaking slit 61 of different shapes and depths is generated, whereby the amount and speed of releasing the active ingredient inside the gel bait 60 can be controlled.

Referring to Fig. 8, in the third preferred embodiment, the bait apparatus of the present invention is purchased from the container 20, the container lid 30 and the gel bait 60. The assembly state between the container 20 and the container lid 30 is the same as that of the first preferred embodiment, and is described herein in detail, in that the gel bait 60 has a plurality of broken slits 61 which increase the evaporation area.

Please refer to FIG. 9A, which is a conventional bait device using the block bait 11 in FIG. 1; see FIG. 10, which is a conventional bait device using a plurality of square baits 12 in FIG. Further, please refer to FIG. 11A, which is a bait device of the present invention. The above two conventional bait devices and the bait device of the present invention are each prepared as a sample, and placed in the same environment, and the trapping results of each bait device are detected and recorded every three days at the same time, that is, Compare the table graph as shown in Figure 12.

Referring to Figure 12, and in conjunction with Figures 9A through 9D, it can be seen that the conventional bait apparatus using the block bait 11 has an optimized attracting effect from the first to the third days after opening. However, after the 12th day, the attracting effect showed a downward trend with respect to the first to third days, and almost no attraction after the 15th day. The reason for this is that after the self-sealing of the conventional bait device using the block bait 11, the attracting component and the moisture of the block bait 11 are both from the upper surface of the block bait 11 Evaporation and diffusion, therefore, after 15 days, the upper surface of the above-mentioned bulk bait 11 has gradually dried up and attenuated and hardened (as shown in Figs. 9C to 9D), so that the inside of the above-mentioned block bait 11 is attracted. The composition is hardened by the above-mentioned block bait 11 and cannot be evaporated and diffused, and the number of attracting fruit flies gradually decreases according to the number of days of use, and even approaches an ineffective state.

Referring to FIGS. 10A to 10D, in order to improve the disadvantage that the conventional bait device using the block bait 11 described above cannot sufficiently evaporate the attracting component, the gel bait 60 is cut into the above plurality of square baits. 12, placed in the above-mentioned container 20 in an irregular manner to increase the surface area of volatilization and diffusion, and then refer to the conventional attracting device using the above-mentioned square bait 12 on the 3rd to 15th day as shown in Fig. 12. The number of attracting fruit flies is significantly increased relative to the conventional bait device using the gel bait 60 of the above-mentioned block bait, and the volatilization time of the attracting component is also extended to the 18th day, but after the 19th day The number of induced fruit flies tends to be absent, because the above-mentioned plurality of square baits 12 can increase the volatilization efficiency of the internal attracting components of the square bait 12, but relatively shorten the service life.

Referring to FIGS. 11A-11D, the present invention uses the plurality of cutting studs 51 to penetrate the gel bait 60 to control the rate at which the gel bait 60 releases the attracting component, and the gel bait 60 is inside. During the process in which the attracting component evaporates and diffuses into the air and gradually becomes dry, a flower-like crack is formed along the edge of the above-mentioned cutting stud 51, and a crack is automatically generated from the top to the bottom to the inside of the gel bait 60, thus, The attracting components of the gel bait 60 described above can be sequentially released, thereby forming a better balance between the attracting effect and the service life. Referring to Fig. 12, the number of fruit flies induced by the attracting device of the present invention from day 1 to day 30 is far superior to the above two conventional attracting devices, and therefore, the gel bait is passed through the above-described breaking device 50. The 60 penetration can effectively control the time when the surface of the gel bait 60 leaves the cutting projection 51 and generate cracks of different shapes and depths, thereby controlling the amount and speed of releasing the active ingredient inside the gel bait 60.
