Description

Technical Field

[0001] The utility model relates to a collecting device, in particular to a collecting device for Indian meal borer larvae. Background Art

[0002] Indian meal moth belongs to the subfamily Pyralidae of the order Lepidoptera. It is also known as the Indian meal moth and the Indian moth. It is one of the important storage pests. In its larval stage, the Indian meal moth can not only harm a variety of dried fruits and various medicinal materials, but also a variety of grains and their processed products. And unlike other borer pests, the larvae of the Indian meal moth can spin silk and weave webs while feeding, which is more harmful. In addition to being pests, the larvae of the Indian meal moth can also serve as artificial hosts to expand the reproduction of a variety of natural enemies.

[0003] In order to realize the indoor breeding and breeding of parasitic wasps of Indian meal moth larvae, people have been exploring how to realize a simple method of collecting Indian meal moth larvae. At present, the Indian meal moth larvae collection device commonly used in laboratories is a transparent insect box, with a 120-mesh gauze on the insect box cover, and artificial feed at the bottom of the insect box. When the Indian meal moth larvae in the insect box grow to the last instar larvae, the insect box cover is opened, and the breeding workers brush some of the larvae that drill out of the feed from the insect box cover and the insect box wall. The other part of the larvae needs to pour the feed into another tray and pick them from the feed. The device for collecting larvae is relatively simple and easy to make. However, there are still some problems with the device during operation: some Indian meal moth larvae are in the feed, and it takes a lot of time and energy to manually pick the larvae. In addition, when collecting Indian meal moth larvae, it is necessary to manually open the lid of the feeding box, pour the feed in the feeding box into another tray, and then find another device to hold the Indian meal moth larvae picked out from the feed. The entire collection process is relatively cumbersome. Utility Model Content

[0018] 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.

[0019] Embodiment of the utility model: a collection device for Indian meal borer larvae, such as Figure 1-5 As shown, it includes a feeding box A1 and a feeding box B2, and a step 3 is fixedly provided on the side of the feeding box A1 and the feeding box B2. The step 3 includes a base and a cylinder on the base. An opening 4 is provided in the step 3 and communicates with the inside of the feeding box. An opening groove running through the left and right sides is provided at the base of the step 3. A baffle 5 is movably connected in the opening groove. The baffle 5 is provided with an opening portion 6 and a shielding portion 7. The cylinders of the two steps 3 are connected through a pipe 8. The cover of the feeding box A1 is densely covered with mesh holes 9. A cover shell 10 is also placed on the cover of the feeding box A1, and a temperature control lamp 11 is provided on the inner top wall of the cover shell 10.

[0020] First, the Indian meal moth is raised and bred in the breeding box A1. When the Indian meal moth larvae in the breeding box A1 grow to the last instar larvae, some larvae need to be collected from the breeding box A1 and bred in the breeding box B2. The process of collecting larvae is to first connect the breeding box A1 and the breeding box B2 together through the pipe 8. When the pipe 8 is installed, it is installed in place when its two ends are against the base step surface of the step 3. When the pipe 8 is installed, the baffle 5 should be moved so that its shielding part 7 blocks the opening 4. After the pipe 8 is installed, the baffle 5 is moved so that its opening part 6 is directly opposite to the opening 4. At this time, the breeding box A1 and the breeding box B2 are connected. Then, a cover 10 is placed on the rearing box A1, and a switch of a temperature-adjusting lamp 11 is turned on. The light of the temperature-adjusting lamp 11 shines into the rearing box A1 through the mesh 9 on the box cover, so that the temperature of the rearing box A1 increases. When the temperature in the rearing box A1 is too high, the Indian meal moth larvae will enter the rearing box B2 through the pipe 8. When a large number of Indian meal moth larvae are collected in the rearing box B2, the opening 4 on the rearing box A1 is first closed, and the pipe 8 is knocked to move the Indian meal moth larvae inside it to the rearing box B2, and then the opening 4 on the rearing box B2 is closed. Finally, the pipe 8 between the rearing box A1 and the rearing box B2 is removed, and the temperature-adjusting lamp 11 is turned off. The process of collecting the Indian meal moth larvae is completed.

[0021] The length of the baffle 5 is equal to twice the width of the base of the step 3, and both ends of the baffle 5 are provided with limit cards 12. Figure 5As shown, when the left limit card 12 contacts the step 3, the opening 6 on the baffle 5 is just aligned with the opening 4, so that the feeding box is connected to the outside, and when the right limit card 12 contacts the step 3, the shielding part 7 on the baffle 5 is just aligned with the opening 4, and the feeding box is in a closed state with the outside. The height of the opening groove is greater than the diameter of the opening 4, so as to avoid a gap between the baffle 5 and the opening 4.

[0022] The step 3 is provided with an annular groove, in which a rubber ring 13 is inserted. When the pipe 8 is connected to the cylinder of the step 3, the rubber ring 13 contacts the inner wall of the pipe 8, ensuring that the pipe 8 is in good contact with the cylinder of the step 3, thereby preventing the pipe 8 from falling off when accidentally touching the pipe 8 or the breeding box.

[0023] The top of the box cover of the feeding box A1 is provided with a limit enclosure 14 extending upward. The cover shell 10 is a square frame structure with an opening at the bottom. When the cover shell 10 is placed, its opening faces the limit enclosure 14 extending into the opening. The outer wall of the limit enclosure 14 fits with the inner wall of the cover shell 10, thereby fixing the cover shell 10 to prevent the cover shell 10 from falling off.

[0024] The structures of the rearing box A1 and the rearing box B2 are exactly the same, so that the rearing box has universality. When the Indian meal moth is reared on a large scale, only one rearing box of structure and size needs to be made, which is much more convenient to make.

[0025] The feeding box A1, the feeding box B2, the pipeline 8 and the cover 10 are all made of transparent materials, so that the internal conditions thereof can be easily observed.
