Description

Technical Field

[0001] The utility model relates to a collecting device, in particular to an Indian meal moth egg collecting device used in a laboratory. Background Art

[0002] Indian meal moth, also known as Indian meal moth, date borer, capping moth, etc., belongs to the order Lepidoptera, family Pyralidae, genus Pyralidae in insect taxonomy. This pest is widely distributed throughout the world. Except for Tibet, it is found in all other provinces, municipalities, and autonomous regions in my country. It is one of the most important grain storage pests that damages stored goods and household grain products. In addition to being a pest, the larvae of Indian meal moth can also serve as artificial hosts for the reproduction of various natural enemies.

[0003] When Indian meal moth is cultivated in the laboratory, the eggs need to be collected during the cultivation process. However, the existing method of collecting Indian meal moth eggs has the following problems:

[0004] 1. The traditional collection method is to collect the adults in a relatively sealed container for cultivation, and a tray is placed at the bottom of the container to collect eggs. This collection method has the following problems:

[0005] 1. The space for adults to move around is large, and many eggs are attached to the wall of the collection bottle, which results in some eggs being wasted and easily causing pollution;

[0006] 2. Each time you collect eggs, you need to clean and replace the tray (used to collect eggs). When taking out the tray, it is easy to overturn the device or fail to hold it firmly, causing the device to fall and cause the adult insects to fly out;

[0007] 3. The adult insect collection device is inconvenient to clean.

[0008] Second, simple mesh bag collection, that is, collect the Indian meal moth adults into the mesh bag, tighten the rope and tie it, then place the mesh bag directly on the surface of the feed, and wait for the larvae to hatch and automatically crawl around. Although this method is simple, the collection efficiency is not high, and the scales of the adults are not cleaned, which is easy to contaminate the feed and eggs, and even cause mites.

DETAILED DESCRIPTION

[0029] 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.

[0030] Embodiment of the utility model: a laboratory-used Indian meal moth egg collection device, such as Figure 1-3As shown, it includes a breeding box 1 with a top opening, a cross bar 2 is arranged at the top of the breeding box 1, a mesh bag 3 is hung on the cross bar 2 by a rope, an inclined screen 4 is arranged inside the breeding box 1 below the mesh bag 3, the tail end of the inclined screen 4 extends from an opening 5 on the side of the breeding box 1, and an egg collecting box 6 is arranged below the tail end of the inclined screen 4 extending to the outside of the breeding box 1, and a scale powder collecting box 7 with a drawer structure is movably arranged at the bottom of the breeding box 1.

[0031] During use, the adults are placed in the mesh bag 3 for cultivation, the eggs produced by the adults pass through the meshes of the mesh bag 3 and fall onto the oblique screen 4, and then the eggs roll along the oblique screen 4 to the egg collection box 6, while the scale powder produced by the adults also passes through the meshes of the mesh bag 3 and falls onto the oblique screen 4, and then passes through the meshes of the oblique screen 4 and falls into the scale powder collection box 7 below. The oblique screen 4 is used to separate and collect the eggs and scale powder.

[0032] A conical collecting cover 8 is fixedly provided on the inner wall of the cultivation box 1 between the scale powder collecting box 7 and the oblique screen 4 , and the scale powder passing through the oblique screen 4 can completely fall into the scale powder collecting box 7 through the conical collecting cover 8 .

[0033] The left and right inner walls at the top of the incubator 1 are provided with bayonet holes 9 , into which the cross bar 2 is inserted, and the bayonet holes 9 are provided so as to fix the cross bar 2 .

[0034] Two mesh bags 3 are arranged at intervals on each cross bar 2, so that more adults can be cultivated. The mesh bags 3 are arranged above the head end of the inclined screen 4, so that the scale powder can fall on the head end of the inclined screen 4. When the scale powder cannot directly pass through the inclined screen 4, there is enough distance for the scale powder to pass through the inclined screen 4 during the process of sliding along the inclined screen 4.

[0035] Two clamping rings 10 are arranged at intervals on the cross bar 2, and the mesh bag 3 is fixed on the clamping rings 10 via ropes. The clamping rings 10 make it easy to know the installation position of the mesh bag 3.

[0036] The two mesh bags 3 on the same crossbar 2 are staggered up and down, and a fan 11 is arranged on the inner wall of the incubator 1 away from the mesh bag 3. The fan 11 blows air toward the mesh bag 3. The fan 11 blows a small wind force toward the mesh bag 3, and under the action of the wind force, the scale powder and the eggs can be more easily dropped out of the mesh bag 3. The two mesh bags 3 are staggered up and down to avoid the situation of wind blocking.

[0037] The size of the oblique screen 4 is 200 meshes, and a better size of 200 meshes can allow the scale powder to pass through the oblique screen 4 while filtering out the insect eggs, thereby achieving effective separation of the scale powder and the insect eggs.

[0038] The outer wall of the head end of the oblique screen 4 is provided with a latch 12, a concave cavity is provided on the left inner wall of the incubator 1, and a limiting groove 13 is provided on the front and rear side walls of the concave cavity, the latch 12 is inserted into the limiting groove 13, the tail end of the oblique screen 4 is supported on the opening 5, and a vibration device is provided at the bottom of the oblique screen 4, and the bottom of the oblique screen 4 is struck by the vibration device, so that the scale powder and insect eggs falling on the oblique screen 4 are easier to fall out.
