Description

Technical Field

[0001] This utility model relates to the field of black soldier fly technology, and in particular to a device for attracting and collecting adult black soldier fly eggs. Background Technology

[0002] The black soldier fly, also known as the shiny-spotted flat-horned soldier fly, is a saprophytic insect belonging to the genus *Bufo* in the family Bandidae of the order Diptera. It measures 13-20 mm in length and is predominantly black with a bluish-purple sheen. Its antennae have bamboo-like tips, and its tibiae are white, while the rest of its legs are black.

[0003] The black soldier fly's life cycle consists of five developmental stages: egg, larva, prepupa, pupa, and adult. It is a holometabolous insect. The development from egg to adult generally takes about 35 days. The egg development cycle is temperature-dependent; it is suitable within a suitable temperature range, but development time is prolonged above this range. Egg development is negatively correlated with environmental humidity; increased humidity affects the hatching rate. Adult black soldier flies mate at midday under strong sunlight. About 2-3 days after mating, the female lays eggs in dry crevices near fresh organic matter. The eggs are oblong, and approximately 800-1000 eggs are laid in clusters. The average lifespan of a female adult is 7-9 days, and that of a male adult is 6-7 days.

[0004] Existing methods for attracting egg-laying insects typically leverage the black soldier fly's preference for dry, secluded crevices. Specific structures such as wooden crevices, corrugated cardboard, and porous fiberboard are used within the rearing shed to simulate a natural egg-laying environment. However, simulating natural crevices cannot concentrate the attractant, potentially leading to insufficient control over the adult egg-laying location and resulting in low egg collection efficiency. This also increases the cost of the rearing facility. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies using natural crevice simulation cannot concentrate the attractant, may not be able to completely control the adult insect's egg-laying location, resulting in low egg collection efficiency and increased breeding site costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a black soldier fly adult oviposition attraction and collection device, comprising a collection box, an oviposition attraction and collection component provided on the surface of the collection box, the oviposition attraction and collection component including a vent hole, connecting blocks connected to both sides of the front end of the collection box, an oviposition net connected to the upper end of the collection box at the vent hole, slots provided on both sides of the oviposition net, magnetic suction blocks inserted into both sides of the collection box, a protective cover connected to the upper surface of the vent hole, an attraction plate provided inside the collection box, fixing blocks connected to both sides of the front end of the attraction plate, a spring connected inside the fixing block, a push plate connected to one side of the spring, a locking block connected to one side of the push plate, and a lever connected to the front end of the push plate.

[0007] Furthermore, the surface of the card block is provided with a bevel, the position and size of the card block match the card slot of the fixing block, and the card block and the card slot form a snap-fit ​​connection, and the beveled card block facilitates connection with the card slot.

[0008] Furthermore, the outer surfaces on both sides of the lure plate are in contact with the inner wall of the collection box, and the push plate and the spring form an elastic structure, which can achieve the purpose of automatic fixation.

[0009] Furthermore, the surface size of the collection box matches the size of the spawning net, and the magnetic plug penetrates through the collection box to form a plug-in connection with the slot, which can fix the spawning net.

[0010] Furthermore, the bottom of the collection box is connected to a lifting adjustment assembly, which includes a main lifting plate. A sleeve is connected to the front surface of the main lifting plate. The lifting adjustment assembly can easily adjust the overall height.

[0011] Furthermore, a hand-tightening bolt is inserted inside the sleeve, and an adjusting bracket is slidably connected inside the main lifting plate. The hand-tightening bolt can easily fix the height of the main lifting plate.

[0012] Furthermore, the surface of the adjusting bracket is provided with threaded holes at equal intervals. The hand-tightening bolt passes through the main lifting plate and forms a threaded connection with the threaded holes. The threaded holes at equal intervals can easily fix the height of the device at different heights.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when collecting adult insect eggs, a natural attractant, such as an attractant product, can be placed in the attractant tray and the attractant tray can be inserted into the collection box. The odor of the attractant product will spread outward through the ventilation holes. After being attracted, the adult insects will adhere to the egg-laying net and lay eggs. The operator can remove the egg-laying net periodically and collect the eggs on the net. This avoids the problem of low egg collection efficiency caused by the inability of traditional collection devices to completely control the location of adult insect egg laying, while also reducing the space occupied and thus reducing the cost of breeding sites.

[0015] 2. In this utility model, by adjusting the conical design at the bottom of the support, the collection box can be inserted into the soil next to the plant bushes for collecting wild species. Through the adjustment of the main lifting plate, it can also be placed in plant bushes at different heights according to actual conditions, thus improving overall practicality.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 3As shown, this utility model provides a device for attracting and collecting adult black soldier fly eggs, including a collection box 1. An egg-laying attraction and collection component 2 is provided on the surface of the collection box 1. The component 2 includes a vent 201. Connecting blocks 202 are connected to both sides of the front end of the collection box 1. An egg-laying net 203 is connected to the upper end of the collection box 1 above the vent 201. Slots 204 are provided on both sides of the egg-laying net 203. Magnetic blocks 205 are inserted into both sides of the collection box 1. A protective cover 206 is connected to the upper surface of the vent 201. An attraction disc 207 is provided inside the collection box 1. Fixing blocks 208 are connected to both sides of the front end of the attraction disc 207. A spring 209 is internally connected to the fixed block 208. A push plate 210 is connected to one side of the spring 209. A locking block 211 is connected to one side of the push plate 210. A lever 212 is connected to the front end of the push plate 210. The surface of the locking block 211 has a bevel. The position and size of the locking block 211 match the slot of the fixed block 208. The locking block 211 and the slot form a locking connection. The outer surfaces of both sides of the attracting disc 207 are in contact with the inner wall of the collection box 1. The push plate 210 and the spring 209 form an elastic structure. The surface size of the collection box 1 matches the size of the spawning net 203. The magnetic insertion block 205 penetrates the collection box 1 and forms a locking connection with the slot 204.

[0024] The effect achieved in Example 1 is that, during the collection of adult insects for oviposition, a constant temperature attractant is achieved, with the temperature controlled at 30-35 degrees Celsius. Natural attractants or attractants can be placed in the attractant tray 207, which is then placed in the collection box 1. The top of the protective cover 206 can be equipped with a fan, depending on the actual situation. The fan blows out the odor of the attractant, or it can be directly combined with indoor airflow to carry out the odor. The odor of the attractant will spread outward through the ventilation holes 201. After being attracted, the adult insects will adhere to the oviposition net 203 to lay eggs. Operators can also periodically remove the oviposition net 203 and clean the contents. The eggs can be collected. When disassembling the oviposition net 203, the two sets of magnetic plugs 205 can be pulled outward so that the magnetic plugs 205 can be pulled out of the slot 204. Then the oviposition net 203 can be removed directly. After collection, the oviposition net 203 is placed on the surface of the collection box 1, and the magnetic plugs 205 are inserted into the slot 204 through the collection box 1 for fixation. When it is necessary to remove the attractant plate 207 for cleaning, the two sets of levers 212 can be pushed to both sides at the same time so that the levers 212 can drive the push plate 210 to squeeze the spring 209, causing the locking block 211 to retract. Then the attractant plate 207 can be pulled outward. After cleaning the attractant tray 207, add the attractant and then push the attractant tray 207 into the collection box 1. The angled opening of the locking block 211 will automatically retract. After the attractant tray 207 is fully pushed into the collection box 1, the spring 209 will push the push plate 210 to drive the locking block 211 into the slot of the fixing block 208 for fixation. This completes the installation of the attractant tray 207, avoiding the problem of low egg collection efficiency caused by the inability to fully control the adult egg-laying position of traditional collection methods. At the same time, it reduces the space occupied, thereby reducing the cost of the breeding site.

[0025] Example 2, as Figure 1 and Figure 4 As shown, the bottom of the collection box 1 is connected to a lifting adjustment assembly 3. The lifting adjustment assembly 3 includes a main lifting plate 301. A sleeve 302 is connected to the front surface of the main lifting plate 301. A hand-tightening bolt 303 is inserted into the sleeve 302. An adjustment bracket 304 is slidably connected inside the main lifting plate 301. Threaded holes 305 are equidistantly opened on the surface of the adjustment bracket 304. The hand-tightening bolt 303 passes through the main lifting plate 301 and forms a threaded connection with the threaded hole 305.

[0026] The effect achieved in Embodiment 2 is that adult insects prefer to stay in plant clumps. By adjusting the conical design at the bottom of the support 304, the collection box 1 can be inserted into the soil next to the plant clump, improving the attraction effect on adult insects. When it is necessary to adjust the height of the collection box 1, the hand-tightening bolt 303 is removed from the threaded hole 305 at the current position, then the position is adjusted, and the hand-tightening bolt 303 is tightened to fix it. By adjusting the height of the main lifting plate 301, it can also be placed in plant clumps at different heights according to actual conditions, thus improving overall practicality.

[0027] Working principle: When collecting adult insect eggs, a natural attractant, such as a attractant product, can be placed in the attractant tray 207 and inserted into the collection box 1. The scent of the attractant product will spread outward through the ventilation holes 201. After being attracted, the adult insects will attach to the egg-laying net 203 and lay their eggs. Operators can periodically remove the egg-laying net 203 and collect the eggs on it. This avoids the problem of low egg collection efficiency caused by the inability of traditional collection devices to completely control the adult insect egg-laying location. It also reduces the space occupied, thereby reducing the cost of breeding sites. By adjusting the conical design at the bottom of the support 304, the collection box 1 can be inserted into the soil next to the plant clump, mainly for collection of wild species. The height-adjustable attractant box can be retained, and the leaves can also be used as a solution to prevent the attractant product from being too close to the ground and causing insect eggs to be laid on the ground. It can also be placed in plant clump trays at different heights according to the actual situation.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
