Classified raising method and imago raising device of corn borers

Abstract

The invention provides a classified raising method and an imago raising device of corn borers. The raising method comprises the following steps: raising initial larvae of corn borers in a 12-bore cell culture plate; after 6-7 days, selecting the strong larvae growing regularly to be raised in a tissue culture bottle; after the larvae grow to old larvae, adding paper pupation device into the tissue culture bottle; and finally selecting strong pupae to be put in an imago cage. The imago raising device of corn borers comprises an inner bottle and an outer cover, wherein the inner bottle is an open-top bottle, the lower part of the bottle is provided with a hole in which a hollow area is arranged, the hollow area is provided with a fine-bore screen, the outer cover is sleeved outside the inner bottle, and the top end of the opening of the outer cover is covered with a white gauze; the opening of the inner bottle is provided with an egg laying substrate, and sterilizing sand is arranged onthe bottom; and the fine-bore screen is also provided with a food feeding pipe. The method can remove sick and weak corn borers and keep the corn borer strong and regular. The device has the advantages of simple structure, low cost, simplicity and practicability, favorable ventilation property and air humility and wide application range.

Description

technical field [0001] The invention relates to an insect feeding method and a device thereof, in particular to a hierarchical feeding method of corn borer and an adult feeding device thereof. Background technique [0002] The conventional feeding method of corn borer is to use a large container, such as a glass tank, as a feeding container. After adding artificial feed, put the egg paper that is about to hatch on the feed block, and the larvae will stay in this container to grow after hatching. until pupation. The biggest defect of this method is that the larvae have not been screened, and obvious individual differences begin to appear after they are raised to 3-4 instars. The entire breeding population is uneven, resulting in irregular pupation, which takes a long time and seriously affects the feeding efficiency; And individual sick insects are also easy to infect the whole group, resulting in an increase in sick and weak individuals, and an increase in deformed pupae, w...

Problems solved by technology

The biggest defect of this method is that the larvae have not been screened, and obvious individual differences begin to appear after they are raised to 3-4 instars. The entire breeding population is uneven, resulting in irregular pupation, which takes a long time and seriously affects the feeding efficiency; Moreover, individual pests are also easy to infect the whole group, resulting in an increase in sick individuals and deformed pupae, which makes it difficult to ensure the robustness of the entire breeding group.

In short, if the larval stage is not selected, it will not only affect the efficiency of contemporary breeding, but also affect the effect of continuous subculture

[0003] Conventional corn borer adult breeding devices are mostly wooden square cages, which are inconvenient to set the ovipositing substrate, and the operation is very troublesome when changing the oviposition substrate every day, and it is easy to cause the adults to escape; the moisturizing of this type of insect cage The function is not strong, and most of them place a small cup of water in the cage to moisturize, so that not only the water evaporation surface is limited, but also it is easy to cause the adult insects to fall into the water by mistake and die

In addition, since this kind of insect cage is not equipped with an outer cover, a large number of scales will be produced by the movement of moths in the cage, which is not only not conducive to the cleanliness of the breeding environment, but also easily causes the scales to be passively inhaled into the respiratory tract of the breeders and affect the health.
