When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] like Figures 1-3As shown, this utility model provides a rearing device for lepidopteran larvae, including a box body 1. A support plate 2 is fixedly installed inside the box body 1. The support plate 2 is annular, and a rearing net box 3 is provided on the support plate 2. The rearing net box 3 can be removed entirely from the box body 1 for easy cleaning, disinfection, and sterilization. The top of the rearing net box 3 is set with an opening, and a top frame 4 is fixedly installed on the top of the rearing net box 3. A hanging frame 5 is fixedly installed on the top frame 4. The hanging frame 5 is U-shaped and is used to hang branches and leaves for rearing larvae, or to hang biomimetic branches and leaves to conform to the growth habits of lepidopteran larvae. A collection drawer 6 for collecting larval feces is provided below the support plate 2 inside the box body 1. A sealed door 7 is provided at the bottom of the box body 1 to allow the collection drawer 6 to enter and exit. A top cover 8 is provided at the top of the box body 1, and a ventilation window 9 is provided on the top cover 8. A ventilation window 9 is also provided at the bottom of the box body 1. Ventilation windows 9 at the bottom of the box 1 are located around the collection drawer 6 to facilitate the evaporation of odors from larval feces. If necessary, a miniature fan can be installed outside the ventilation windows 9 to enhance air circulation.

[0027] In this embodiment, the breeding net cage 3 includes a bottom plate 301 and an annular plate 302. The bottom plate 301 and the annular plate 302 are made of metal mesh. An annular connecting seat 303 is fixedly installed on the bottom plate 301. The annular plate 302 and the annular connecting seat 303 are vertically slidably connected. A connecting hole is provided at the bottom end of the annular plate 302 and on the annular connecting seat 303. A connecting pin is provided in the connecting hole.

[0033] When control switch 11 is in automatic mode, if the light sensor detects that the light intensity is less than a preset threshold, power is not supplied to the color-changing observation window 10, and the photochromic unit automatically adjusts the light entering the housing 1; if the light sensor detects that the light intensity is greater than or equal to the threshold, the electrochromic unit of the color-changing observation window 10 is automatically adjusted to automatically adjust the light entering the housing 1.

[0034] This is to ensure that the light intensity inside the box matches the growth habits of lepidopteran larvae.

[0035] When it is necessary to observe the lepidopteran larvae inside the box 1, switch the control switch 11 to manual mode, power the color-changing observation window 10 with the control switch 11, manually adjust the voltage of the electrochromic unit of the color-changing observation window 10, and manually change the light transmittance of the color-changing observation window 10 for observation.

[0036] In this embodiment, one side of the sealing door 7 is hinged to the box body 1, and a connecting plate 701 is fixedly installed on the other side of the sealing door 7. Magnetic plates are respectively provided on the connecting plate 701 and the box body 1. The two magnetic plates are magnetically engaged to facilitate opening and closing, so as to take out the collection drawer 6 for cleaning. A ventilation window 9 is provided on the sealing door 7, and a handle is fixedly installed on the sealing door 7 for easy operation.

[0037] In this embodiment, a handle is fixedly installed on the top cover 8 to facilitate opening the box 1 and adding feed or branches and leaves for feeding into the box 1.

[0038] When in use, hang branches and leaves for raising lepidopteran larvae on the hanging frame 5, or hang biomimetic branches and leaves so that the raised larvae are suspended on the biomimetic branches and leaves, in accordance with the growth habits of lepidopteran larvae.

[0039] Place the breeding net cage 3 inside the box body 1 and close the top cover 8.

[0040] When observing lepidopteran larvae, switch control switch 11 to manual mode. Control switch 11 supplies power to the color-changing observation window 10. Manually adjust the voltage of the electrochromic unit of the color-changing observation window 10 to manually change the light transmittance of the color-changing observation window 10 for easier observation. After observation, switch control switch 11 back to automatic mode.

[0041] When it is necessary to clean up the larval feces, open the sealed door 7, take out the collection drawer 6, clean the collection drawer 6 in time, and put it back in place after cleaning.

[0042] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model.
