The bottom surface of the culture tray 3 is fixedly connected to the first oscillation motor 5. The first oscillation motor 5 imitates external interference and better drives the larvae on the upper surface of the first culture layer 4 to move toward the outer surface of the ramp plate 9.

The unemerged pupal larvae are blocked by the filter screen 39 and remain in the inside of the bottom box 1. The deformed winged adult individuals are retained in the middle of the culture chamber 2 due to their insufficient flying ability and the effect of moving upward with the help of wind force is not as good as that of healthy winged adult fruit flies.

[0036] The bottom box 1 is provided with a cavity 15 inside, and piston cylinders 16 are inlaid on the left and right side walls of the cavity 15. The piston cylinder 16 is connected to the nozzle 13 through a first one-way valve 20. The nozzles 13 arranged on the left and right side walls of the bottom box 1 are respectively connected to a water bottle 14 fixedly connected to the front of the bottom box 1. The water bottle 14 is connected to the inside of the piston cylinder 16 through a second one-way valve 21. The piston rods 17 slidably connected to the inner walls of the two piston cylinders 16 are both slidably connected to the eccentric wheel 18 arranged inside the cavity 15. The end of the piston rod 17 that is close to each other is always in contact with the outer surface of the eccentric wheel 18.

[0037] The liquid outlet end of the first one-way valve 20 is connected to the nozzle 13, and the liquid inlet end of the first one-way valve 20 and the liquid outlet end of the second one-way valve 21 are both connected to the inside of the piston cylinder 16, and the liquid inlet end of the second one-way valve 21 is connected to the water bottle 14, ensuring the flow direction of the liquid inside the piston cylinder 16, that is, the operation of the motor 19 drives the eccentric wheel 18 to rotate inside the cavity 15, and under the cooperation of the telescopic spring 22, drives the piston rods 17 on both sides to move left and right on the inner wall of the piston cylinder 16, so that the liquid inside the water bottle 14 is sprayed onto the outer surface of the first culture layer 4 and the sponge block 10 respectively through the second one-way valve 21, the piston cylinder 16, the first one-way valve 20 and the nozzle 13, and the interiors of the left and right water bottles 14 are respectively filled with menthol. The invention discloses a method for preparing a larvae culture medium comprising: preparing a larvae culture medium comprising: a solution and an ethyl acetate solution, wherein menthol is a low concentration insect repellent, which drives the larvae to move toward the slope, and ethyl acetate is a natural pheromone component of fruit flies, which attracts the larvae to gather, so that the larvae on the upper surface of the first culture layer 4 can crawl toward the surface of the slope plate 9, and the sponge block 10 provides conditions for the larvae to pupate. The operation of the fan 12 is conducive to the adult fruit flies that have emerged on the outer surface of the sponge block 10 to better move to the upper part of the culture bin 2 through the filter screen 39 and the isolation funnel plate 6 with the help of wind force, and the unemerged pupated larvae are retained in the interior of the bottom box 1 under the obstruction of the filter screen 39, and the deformed winged adult individuals are retained in the middle part of the culture bin 2 due to their insufficient flying ability and the fact that they cannot move upward with the help of wind force as well as the healthy winged adult fruit flies, and the sponge block 10 is arranged to facilitate the attachment of the pupae.

[0038] A through slot 28 is provided on the right side wall of the culture bin 2, and a piston plate 30 is slidably connected to the inner wall of the piston slot 29 provided on the inner bottom wall of the through slot 28, and the output end of the electric telescopic rod 33 fixedly connected to the right side of the bottom box 1 is fixedly connected to the induced draft fan 34, and the two piston plates 30 are fixedly connected to the air inlet end of the induced draft fan 34, and the air outlet end of the induced draft fan 34 is clamped with a dust collecting bag 35, and the electric telescopic rod 33 can drive the air inlet end of the induced draft fan 34 to move up and down inside the culture bin 2, so as to better suck out the deformed winged adult fruit flies in the middle of the culture bin 2, and at the same time, it can drive the piston plate 30 to move up and down inside the piston slot 29, and the inner walls of the two piston slots 29 are fixedly connected with a group of first check valves 31 and second check valves 32, and the air outlet end of each first check valve 31 is connected to the interior of the culture bin 2, and the air inlet end of each first check valve 31 and the air outlet end of the second check valve 32 are connected to the interior of the piston slot 29, and each second check valve The air inlet ends of 32 are connected to the outside, ensuring the flow direction of the air inside the piston groove 29, that is, when the piston plate 30 moves up and down inside the piston groove 29, the external air flows into the interior of the culture bin 2 through the second check valve 32, the piston groove 29 and the first check valve 31, increasing the circulation of the air inside the culture bin 2. At the same time, the air flowing out of the upper first check valve 31 forms a wind screen, which has the effect of blocking the upward movement of the adults with deformed wings, which is beneficial for the subsequent induced draft fan 34 to suck out the adults with deformed wings inside the culture bin 2. The left side wall of the culture bin 2 is inlaid with an air permeable net 38. The setting of the air permeable net 38 can better drive the adults with deformed wings in the middle of the culture bin 2 to follow the air flow and be collected into the dust bag 35. The aperture diameter value of the air permeable net 38 is smaller than the diameter value of the adults, preventing the adults inside the culture bin 2 from flying out. The device better stratifies the hatching process of fruit flies, slows down the predation or competition at different stages of the hatching process, and also saves manual sorting.

[0039] Working principle: When in use, add menthol solution and ethyl acetate solution into the left and right water bottles 14 respectively, connect the first oscillation motor 5, motor 19, second oscillation motor 24, through hole 27 and electric telescopic rod 33 with the mobile power supply, and the first oscillation motor 5 imitates external interference to drive the larvae on the upper surface of the first culture medium layer 4 to crawl to the outer surface of the ramp plate 9. At the same time, the operation of the motor 19 drives the eccentric wheel 18 to rotate, and drives the piston rods 17 on both sides to move left and right on the inner wall of the piston cylinder 16, so that the menthol solution and ethyl acetate solution in the water bottle 14 are sprayed to the outer surface of the first culture medium layer 4 and the sponge block 10 through the nozzle 13, respectively, to drive the larvae to move toward the slope. Ethyl acetate is a natural pheromone component of fruit flies, which attracts larvae to gather, so that the larvae on the upper surface of the first culture medium layer 4 can crawl to the surface of the ramp plate 9 and on the sponge block. The outer surface of the sponge block 10 is pupated, and the operation of the fan 12 is conducive to the adult fruit flies that have emerged on the outer surface of the sponge block 10 to better move to the upper part of the culture bin 2 through the filter screen 39 and the isolation funnel plate 6 with the help of wind. The pupated larvae that have not emerged are blocked by the filter screen 39 and stay in the inside of the bottom box 1. The deformed winged adult individuals are retained in the middle of the culture bin 2 due to insufficient flying ability and the effect of moving up with the help of wind is not as good as that of healthy winged adult fruit flies. The electric telescopic rod 33 can drive the air inlet end of the induced draft fan 34 to move up and down inside the culture bin 2, so as to better absorb the deformed winged adult fruit flies in the middle of the culture bin 2. At the same time, it can drive the piston plate 30 to move up and down inside the piston groove 29 to absorb the deformed winged adults in the culture bin 2. The device better stratifies the hatching process of fruit flies, slows down the predation or competition that occurs at different stages during the hatching process, and also saves manual sorting.
