Description

Technical Field

[0001] This utility model relates to a black soldier fly egg collection device, belonging to the field of insect breeding technology. Background Technology

[0002] Black soldier fly (Hermitia illucens) is a novel forage insect that has been widely promoted and applied throughout China for the resource recovery of kitchen waste, livestock manure, and other wastes, producing high-quality animal protein feed. Currently, black soldier fly bodies are successfully used as animal feed in poultry and aquaculture. Black soldier fly farming has become a promising emerging industry, and the laying and collection of black soldier fly eggs is a crucial step, requiring efficient equipment.

[0003] Most existing methods for collecting horsefly eggs in the industry use corrugated cardboard, wooden boards, or plastic boards. These boards are placed on an egg-collecting substrate, where the acidic odor attracts adult horseflies to lay their eggs. However, these methods have several insurmountable drawbacks. For example, corrugated cardboard has a complex structure and comes in various thicknesses, making egg collection inconvenient and prone to damage. Young horseflies also have difficulty crawling out, resulting in a high mortality rate. Wooden or plastic boards are costly for collecting eggs and are difficult to transport and sell together with the egg-laying board. Scraping the eggs results in significant egg loss and requires considerable labor. Relying solely on odor to attract adult horseflies to lay eggs has limited effectiveness; multiple attraction methods are needed to encourage adults to lay eggs in concentrated, high-density locations.

[0004] This shows that current black soldier fly egg collection devices have various shortcomings and cannot meet the needs of industrial-scale black soldier fly egg collection. Utility Model Content

[0005] In view of the shortcomings of the existing technology and to solve the above-mentioned technical problems, this utility model provides a black soldier fly egg collection device.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A black soldier fly egg collection device includes a frame, which is equipped with an attraction lamp or attraction box. The attraction box contains an attractant. Multiple collection troughs are arranged sequentially from top to bottom within the frame. The spacing between adjacent collection troughs is 8mm to 15mm, preferably 12mm. Each collection trough consists of upper and lower collection strips, with a spacing of 2mm to 4mm, preferably 3mm, between the upper and lower collection strips.

[0008] The left end of the collection strip is located in a groove on the inner wall of the left side of the frame, and the right end of the collection strip is located in a groove on the inner wall of the right side of the frame. The groove is provided with a clamping component, which is used to limit the collection strip within the groove.

[0009] The clamping component is a wedge-shaped block or a spring.

[0010] The spring has a protrusion on one side, and the tail end of the spring is inserted into the spring slot. The spring slot is located at the bottom of the groove. After the spring is inserted into the spring slot, the protrusion presses against the side wall of the groove.

[0011] The width of the collection strip is 20mm to 40mm, preferably 30mm. A collection strip with a width of 20mm to 40mm ensures that the female black soldier fly can lay eggs on both sides of the A4 paper, and also makes it easier for the larvae to crawl out of the collection trough.

[0012] The attractant lamp is suspended from the top of the frame, and the distance between the attractant lamp and the uppermost collection bar is equal to or greater than 100 mm. The attractant lamp has a good attraction effect on female black soldier flies, while ensuring that the fly eggs are not damaged by the irradiation.

[0013] The lure box is located at the bottom of the frame, and the distance between the lure box and the bottommost collection bar is equal to or greater than 50mm.

[0014] The attractant box includes an attractant container with a cover plate and vents on the cover plate. The attractant evaporates outward through the vents, which inhibit the evaporation efficiency of the attractant and reduce its stimulation of horsefly eggs.

[0015] To facilitate the hanging and standing of the collection device, a hanging ring is provided at the top of the frame and a support is provided at the bottom of the frame.

[0016] The collection strips arranged sequentially from top to bottom in this invention facilitate the female black soldier fly to climb on both sides and lay eggs in both directions. The 8mm to 15mm spacing between adjacent collection tanks ensures that the female black soldier fly lays eggs only in the space within the collection tank, thereby improving the hatching rate of the fly eggs.

[0017] The collection strip of this invention can be made of common A4 paper. A4 paper is flat and tough, easy to cut, easy to store, and inexpensive. It does not need to be recycled and can be transported and sold together with the laid eggs, thus improving the survival rate of black soldier fly eggs. This invention uses a clamping component to limit the end of the collection strip, which facilitates the disassembly, assembly, and replacement of the collection strip. This invention can effectively induce female black soldier flies to lay eggs in concentrated areas by using an attraction lamp, an attraction agent, or a combination of both, thereby increasing the egg-laying density.

Then, deform the spring piece 3 so that the protrusion 31 moves away from the inner wall of the groove 23. After inserting the end of the collecting strip between the protrusion 31 and the side wall of the groove 23, the spring piece 3 returns to its original shape, and the protrusion 31 presses the collecting strip against the side wall of the groove 23, thus clamping and limiting the collecting strip. Alternatively, the collecting strip can be inserted into the groove 23 first, and then the tail end of the spring piece 3 can be inserted into the spring piece slot 24. After the tail end of the spring piece 3 is inserted into the spring piece slot 24, the protrusion 31 presses the collecting strip against the side wall of the groove 23. Of course, as another embodiment, the clamping component can also be a wedge block or other common clamping components, as long as it can limit the collecting strip within the groove 23.

[0026] A lure box is provided at the bottom of the frame 1, and the distance between the lure box and the bottommost collection strip is equal to 50mm. Of course, in other embodiments, the distance between the lure box and the bottommost collection strip can also be greater than 50mm.

[0027] The attractant box includes an attractant container 5 on the frame 1. The attractant container 5 contains an attractant, which is a methyl acrylate solution of 1 to 10 μg / μL or other common black soldier fly attractants. The attractant container 5 is provided with a cover plate 6, and the cover plate 6 is provided with vent holes 61.

[0028] An attraction light 4 is installed at the top of the frame 1 and is suspended from the top of the frame 1. The attraction light 4 is a 20W LED tungsten iodine lamp, and the distance between the attraction light 4 and the uppermost collection bar is 100mm. Of course, as another embodiment, the distance between the attraction light 4 and the uppermost collection bar can also be greater than 100mm, and the attraction light 4 can also be other attraction lights that can attract black soldier flies.

[0029] To facilitate the hanging and standing of the collection device, a hanging ring 7 is provided at the top of the frame 1, and a bracket is provided at the bottom of the frame 1.

[0030] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
