Abstract
Description
Technical Field
[0001] The utility model relates to a device for collecting rice moth eggs in a laboratory, belonging to the relevant field of rice moth breeding technology. Background Art
[0002] The rice moth is a serious pest of several important stored food commodities, such as rice, wheat, corn, sorghum, peanuts, cottonseed, coffee, spices and cocoa beans. Particularly in tropical areas, the rice moth larvae can cause considerable damage to stored foods as they feed, leaving behind a web of silk wherever they move. The webs formed are noticeably dense and tough, causing significant damage. However, the rice moth eggs have been widely used as an effective alternative host for mass rearing of many biological control agents, such as the trichogrammatid fly.
[0003] At present, the common laboratory process of collecting rice moth eggs is: raise rice moths with a transparent plastic box, move the plastic box into the insect cage after the rice moths emerge as adults, open the lid, let the rice moth adults fly out freely, and then use a transparent plastic tube to collect the adults in the insect cage, and then transfer the collected adults to a plastic jar with air-permeable mesh holes above and below, collect about 200 adults, place the plastic jar on a round tray, and collect its eggs after laying eggs. The device collects eggs cumbersome, and the breeder needs to contact the rice moth adults in the process of collecting rice moth eggs. A large amount of tiny scales will be produced during the flight of the rice moth adults, which will threaten the health of the breeder. Utility Model Content
[0004] The utility model aims to provide a device for collecting rice moth eggs in a laboratory. The device of the utility model is relatively simple to collect eggs, and during the collection process, breeders will not come into contact with rice moth adults, thereby ensuring the health of breeders.
[0005] The technical solution of the utility model is as follows: a device for collecting rice moth eggs in a laboratory comprises an adult breeding box with a top opening, the top of the adult breeding box is a downwardly inclined structure, a gauze device is fixedly arranged at the top opening of the adult breeding box, the gauze device comprises fixed clamping plates at front and rear sides, a gauze is installed between the fixed clamping plates at both sides, the mesh size of the gauze is 120 meshes, the bottom of the fixed clamping plate is fixed on the top of the side wall of the adult breeding box, the bottom of the gauze device extends downward to the outside of the adult breeding box, and an egg collecting box is arranged therebelow.
[0006] In the aforementioned laboratory device for collecting rice moth eggs, baffles are provided on both the front and rear sides of the surface of the gauze device.
[0007] In the aforementioned laboratory device for collecting rice moth eggs, a blow pipe is arranged at the top of the gauze device along its width direction, and a plurality of blow holes facing the gauze direction are arranged at intervals on the blow pipe.
[0008] In the aforementioned laboratory device for collecting rice moth eggs, the front and rear edges of the top of the adult breeding box are provided with flange plates extending outward, and the bottom of the fixed clamping plate is fixed to the top of the side wall of the adult breeding box and the flange plate.
[0009] In the aforementioned laboratory device for collecting rice moth eggs, oblique slide plates are staggered up and down on the inner wall of the egg collection box.
[0010] In the aforementioned laboratory device for collecting rice moth eggs, a drawer is provided at the bottom of the adult rearing box.
[0011] In the aforementioned laboratory device for collecting rice moth eggs, the adult rearing box is made of transparent material.
[0012] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model is provided with a gauze device at the top of the adult breeding box with an inclined structure at the top. During the breeding process in the adult breeding box, the rice moth adults like to cling to the gauze, and the tail tip thereof extends from the mesh to the surface of the gauze, and lays eggs on the surface of the gauze. The 120-mesh gauze can make the tail of the adults extend, but the eggs cannot fall into the adult breeding box. The eggs will fall along the gauze into the egg collection box, thereby realizing the automatic collection of eggs. By providing a blow pipe, the collection of eggs can be better realized under the action of wind. The device has a simple structure and is easy to use, and can realize the automatic collection of eggs. During the entire collection process, the adults cannot fly out of the adult breeding box, which avoids the rice moth adults from contacting the breeder and posing a threat to the breeder's health.

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0018] Embodiment of the utility model: a device for collecting rice moth eggs in a laboratory, such as Figure 1-3As shown, it includes an adult breeding box 1 with a top opening, the top of the adult breeding box 1 is a downward inclined structure, a gauze device 2 is fixedly arranged at the top opening of the adult breeding box 1, the gauze device 2 includes fixed clamping plates 3 on the front and rear sides, the fixed clamping plates 3 include an upper clamping plate and a lower clamping plate, one end of a gauze 4 is clamped and fixed on each side by the upper clamping plate and the lower clamping plate, a gauze 4 is clamped and installed between the fixed clamping plates 3 on both sides, the mesh size of the gauze 4 is 120 meshes, the bottom of the fixed clamping plate 3 is fixed on the top of the side wall of the adult breeding box 1, the bottom of the gauze device 2 extends downward to the outside of the adult breeding box 1, and an egg collecting box 5 is arranged below the gauze device 2.
[0019] During use, rice moth adult moves in adult breeding box 1, rice moth adult likes to cling to gauze 4 in adult breeding box breeding process, its tail tip extends from the mesh of gauze 4 to gauze 4 surface, and eggs are produced to gauze 4 surface, and 120 mesh gauze 4 can make adult tail extend, but worm eggs cannot fall into adult breeding box 1 by gauze 4, so that worm eggs can be made to fall in worm egg collection box 5 along gauze 4, thereby realizing automatic collection of worm eggs. The device is simple in structure, easy to use, and can realize automatic collection of worm eggs. In the whole collection process, rice moth adult cannot fly out from adult breeding box 1, and it is avoided that rice moth adult contacts with breeder and threatens the health of breeder.
[0020] Baffles 6 are provided on both the front and rear sides of the surface of the gauze device 2 to prevent the eggs from falling out from the front and rear edges of the gauze device 2 during the rolling process.
[0021] The top of the gauze device 2 is provided with a blow pipe 7 along its width direction, and the blow pipe 7 is provided with a plurality of blow ports facing the gauze 4 at intervals, and the blow pipe 7 is connected to the blow device, and the wind is blown out from the blow ports on the blow pipe 7 to act on the surface of the gauze 4, so that the eggs attached to the gauze 4 can fall into the egg collection box 5. The blow device can be set to blow air regularly, once every period of time. For some eggs that cannot be blown away by blowing, a brush can be used to brush them off from the gauze 4.
[0022] The front and rear edges of the top of the adult breeding box 1 are provided with flange plates 8 extending outward, and the bottom of the fixed clamping plate 3 is fixed to the top of the side wall of the adult breeding box 1 and the flange plate 8.
