The other end of each of the three water absorbing strips 9 extends downward into the water outlet 10. The water outlet 10 is arranged perpendicularly to the three water absorbing strips 9.

[0032] Water can be poured into the water tank 11 through the water inlet 6, one end of the water absorbing strip 9 is inserted into the water outlet 10 and is in contact with water, so that water is adsorbed, and then the water absorbing strip 9 conducts the water to the moisturizing layer 7, the fruit fly pupae need a certain humidity during pupation and parasitization, the moisturizing layer 7 keeps moist to avoid the fruit fly pupae from drying to affect development, ensure normal development of the fruit fly pupae, and improve the parasitization success rate of parasitic bees.

[0033] The moisturizing layer 7 is made of sponge material, and nanometer sponge with better moisturizing performance can also be used.

[0034] The sponge material has strong water retention, the moisturizing layer 7 made of sponge material can keep the moisturizing layer 7 moist for a long time, provides a stable humidity environment for the fruit fly pupae (the fruit fly pupae have high requirements for humidity during pupation and parasitization, the moisturizing layer 7 can avoid the fruit fly pupae from developing poorly or dying due to insufficient water), and improves the parasitization success rate of parasitic bees.

[0035] The box body 1 and the box cover 2 are made of yellow plastic, and the box body 1 and the box cover 2 are detachably connected through buckles.
