Description

Technical Field

[0001] This utility model relates to the field of insect breeding technology, and in particular to a black soldier fly small unit breeding test box. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Hemiberlesiae*, capable of feeding on animal feces and household waste to produce high-value animal protein feed. Currently, large-scale breeding of black soldier flies still faces numerous technical challenges, particularly in achieving efficient and controllable breeding processes in small-scale experimental environments. Existing black soldier fly breeding devices suffer from poor ventilation, leading to poor gas circulation within the chamber and affecting insect health and breeding efficiency. Furthermore, the structural design does not adequately consider the requirements for ease of operation and precise environmental control during the experimental phase; for example, key operations such as egg collection and watering lack zoned and centralized management. Therefore, there is an urgent need for a compact, environmentally controllable, and easy-to-operate minimum breeding unit experimental chamber to meet the needs of independent control of multiple factors such as light, ventilation, and humidity in black soldier fly breeding experiments, thereby improving the reliability and repeatability of experimental data.

[0022] Reference Figures 1 to 4 A black soldier fly small unit breeding test box according to an embodiment of the present invention includes a box body 100, which is divided into a dark chamber 101 for black soldier fly pupation and emergence, and multiple adult chambers for adult mating, egg laying and drinking.

[0023] The box 100 is equipped with a first partition 104 and a second partition 105. The first partition 104 extends vertically, and the second partition 105 extends horizontally. A channel 110 is provided at the intersection of the first partition 104 and the second partition 105, thereby dividing the space inside the box 100 into multiple chambers. Specifically, the adult chamber includes a first chamber 106, a second chamber 107, and a third chamber 108. The first chamber 106 and the second chamber 107 are located at the upper part of the box 100, and the third chamber 108 is located beside the dark chamber 101. Each adult chamber is equipped with a water storage device 115 and an egg box 114. The water storage device 115 is fixedly installed on the inner wall of the adult chamber, and its interior is equipped with an absorbent sponge. Its water inlet extends to the outer wall of the box 100, forming a water inlet 116. Staff can add water to the water storage device 115 directly from the outside of the chamber through the water inlet 116 without opening the chamber door, simplifying daily maintenance and avoiding the escape of insects and environmental disturbance that might occur if the chamber is opened. The egg box 114 is used to place egg attractants to attract adult insects to lay eggs. The outlet of the egg box 114 also extends to the outer wall of the chamber 100, forming an egg collection port 117. The egg box 114 can be pulled out simply by pulling it out through the egg collection port 117, again without opening the main chamber, ensuring the continuity and stability of the experiment.

[0024] To achieve light isolation, the four walls of darkroom 101 are covered with a light-blocking and heat-insulating film. The inner side of this film is black, and the outer side is white. The inner black layer effectively absorbs and blocks external light from entering, providing the necessary complete darkness for the black soldier fly's pupal and eclosion stages; the outer white layer reflects most of the sunlight or ambient light radiation, significantly reducing the internal temperature rise caused by heat absorption, maintaining a relatively stable internal temperature in darkroom 101, and creating a stable microclimate that conforms to the biological habits of the black soldier fly.

[0025] At least one pupal box 103 is placed on the inner floor of the dark chamber 101 to hold black soldier fly pupae about to emerge. An exhaust fan 102 is installed on one side wall of the dark chamber 101. This fan continuously and gently blows outside air into the dark chamber 101 after filtering it through its filter, achieving positive pressure airflow. Firstly, this ensures sufficient oxygen within the dark chamber 101 and promptly removes harmful gases such as carbon dioxide produced by the insects' metabolism. Secondly, the continuously supplied fresh air helps regulate the humidity within the dark chamber, preventing excessive moisture that could lead to mold growth. Simultaneously, this positive airflow within the dark chamber 101 overflows outward through the channel 110, thus gently and effectively guiding the newly emerged, gas-attracting adults to actively fly towards the channel 110.

[0026] Understandably, the channel 110 is located in the central part of the housing 100, and a flip-up first baffle 111 is provided at the connection point between the channel 110 and the dark chamber 101. When the first baffle 111 is closed, it can effectively prevent adult insects in the dark chamber 101 from entering the channel 110. This design can be used for batch management or cleaning operations. When it is necessary to allow adult insects to enter the adult insect chamber, simply flip the first baffle 111 open, and the channel 110 will be fully connected to the dark chamber 101, allowing the emerging adult insects in the dark chamber 101 to smoothly enter the channel 110.

[0027] Understandably, after emerging from channel 110, adult insects can fly to different adult chambers. To achieve selective opening and management of different adult chambers, movable baffle structures are also installed between channel 110 and each adult chamber. Specifically, a pivotable second baffle 112 is installed between channel 110 and the third chamber 108, with its rotation axis mounted on a horizontal second partition 105. A pivotable third baffle 113 is installed between channel 110 and the upper first chamber 106, with its rotation axis mounted on a vertical first partition 104. By controlling the opening and closing of the second baffle 112 and the third baffle 113, the operator can flexibly decide which one or more adult chambers the adult insects will be guided to, which greatly facilitates genetic diversity management or comparative experiments.

[0028] In this embodiment, the first chamber 106 and the second chamber 107 are located side by side at the top of the box 100, that is, at the top of the dark chamber 101, while the third chamber 108 is located on the side of the dark chamber 101. This multi-space layout provides more activity and mating space for adults, which helps to improve the overall mating rate and egg production.

[0029] Understandably, an air pump 109 is integrated into the egg collection port 117. The air pump 109 continuously pumps fresh outside air into the adult chamber, working in conjunction with the exhaust fan 102 of the dark chamber 101 to create effective air circulation within the housing 100. Furthermore, this directional airflow passes precisely near the egg box 114. Because black soldier fly adults are attracted to air, they are drawn to this weak but continuous airflow, increasing their probability of gathering and moving near the egg box 114, thereby increasing the concentration of their egg-laying on the ovipositors within the egg box 114. This directly improves the convenience and efficiency of egg collection, ensuring that the eggs are not scattered in various corners of the adult chamber.

[0030] To complete the gas circulation loop of the entire enclosure 100, multiple exhaust vents 118 are provided at the top of the enclosure 100, corresponding to the positions of each adult chamber. The exhaust vents 118 are covered with a dense mesh, typically around 100 mesh. The mesh ensures smooth airflow and maintains air pressure balance within the enclosure; it also effectively prevents external pests and debris from entering the enclosure through the exhaust vents and contaminating the breeding environment.

[0031] To facilitate thorough cleaning, maintenance, or repair of the entire test chamber, multiple sides of the chamber 100 are designed with openable structures. Specifically, detachable door panels 119 can be inserted into the outer wall of the chamber 100. These door panels 119 are secured by simple pins or clips and can be easily removed when needed, providing significant convenience for cleaning the interior corners of the chamber and adjusting the equipment.

[0032] The workflow of this invention is briefly described as follows: Mature black soldier fly larvae or pre-pupae are placed in the pupal box 103 of the dark chamber 101. The first baffle 111 is closed for a period of time until most of them emerge as adults, then the first baffle 111 is opened. The exhaust fan 102 inside the dark chamber 101 continuously blows air inward, creating positive pressure and directional airflow to guide the adults out through the channel 110. By controlling the opening and closing of the second baffle 112 and the third baffle 113, the adults are distributed to different adult chambers. In the adult chamber, the adults are attracted by the airflow generated by the air pump 109 at the egg collection port 117 and gather on the egg box 114 to lay eggs. The staff regularly replenishes water from the water inlet 116 outside the chamber and removes the egg box 114 from the egg collection port 117 to collect the eggs. Air is supplied into the chamber by an air pump 109 and an exhaust fan 102. After circulating inside the chamber, the air is finally discharged through the mesh exhaust port 118 at the top, forming a complete and controllable breeding environment.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
