Rice stem borer larva artificial feed and preparation method and application thereof

Abstract

The invention discloses rice stem borer larva artificial feed and a preparation method and application thereof. The feed is prepared from, by mass, 3.96-4.52% of rice stem powder, 1.97-2.26% of rice chaff powder, 0.58-0.68% of yeast powder, 2.31-2.71% of casein, 1.16-1.36% of cane sugar, 0.23-0.27% of vitamin C, 0.12-0.14% of mixed vitamin, 0.12-0.14% of vitamin E, 0.06-0.07% of cholesterol, 0.06-0.07% of choline chloride, 0.52-0.54% of sorbic acid, 0.17-0.23% of kanamycin, 1.97-2.26% of agar powder and the balance distilled water. Raw materials of the feed are easy to obtain. The preparation process is simple, the quantity of insects bred per unit is large, growth is uniform, and bioassay and other biologic tests are convenient.

Description

technical field [0001] The invention relates to an artificial feed for insects, in particular to a preparation method and application of an artificial feed for rice stem borer larvae. Background technique [0002] Chilosuppressalis Walker (Chilosuppressalis Walker) belongs to the family Lepidoptera Boreridae, commonly known as "borer". It damages stems through larvae, causing symptoms such as "dry heart" and "white ears" of rice. It is one of the important pests in rice production in my country. , the damage area and loss are very huge every year. Rearing a large number of Chilo suppressalis larvae with consistent genetic background and neat development throughout the year is the basis for carrying out studies on ecology, toxicology, behavior, and indoor bioassays. At present, domestic studies on the breeding of rice stem borer mainly use rice seedlings, rice stems or other natural hosts (such as water chestnuts, wild rice stems, corn, etc.) to raise rice stem borers, but na...

AI Technical Summary

Problems solved by technology

At present, domestic studies on the breeding of rice stem borer mainly use rice seedlings, rice stems or other natural hosts (such as water chestnuts, wild rice stems, corn, etc.) to raise rice stem borers, but natural host breeding has the disadvantages of perishability and high labor costs. There are also studies on feeding with semi-artificial or artificial formula feeds, most of which have many ingredients, such as rice stem powder + soybean powder, rice stem powder + wild rice stem powder, rice stem powder + corn flour, etc., to prepare The process is still cumbersome, so the cost of feeding is high, and its application is limited to a certain extent; moreover, from the perspective of the genetic background of the population of C.
