Problems solved by technology

[0006] The existing lepidopteran artificial feed used to produce insecticides for insect viruses has relatively complex raw materials. Its main ingredients are soybean powder and commercially available tomato paste, and it contains a variety of commercially available high-grade supplements and medical antibiotics, such as ginseng and royal jelly , Jinshi Erkang, compound vitamins, penicillin, cephalosporin and other additives, resulting in increased cost of artificial feed raw materials and complicated preparation procedures

Abstract

The present invention relates to one kind of artificial feed for raising larvae of lepidopterous insect, and the recipe consists of beer yeast powder, wheat plumule powder, tomato, food preservative, vitamin C, edible oil, agar and water. The present invention also relates to the preparation process of the feed. The feed of the present invention has low cost, easy compounding, stable feeding effect and powerful practicability.

Description

technical field [0001] The invention relates to an artificial feed for raising insects, and further relates to an artificial feed formula and a preparation method for large-scale feeding of Lepidoptera insect larvae. technical background [0002] Due to the general resistance of agricultural and forestry pests to chemical pesticides, the amount of chemical pesticides per unit area is getting higher and higher, and the harm to the environment, non-target animals, biodiversity and human beings is becoming more and more serious. A large number of highly toxic and high-residue pesticides have been restricted, banned, restricted and banned by the Chinese government. In this context, the production, development and application of insecticides, as the earliest developed and widely used biopesticides, are developing rapidly, and the market demand is increasing year by year. [0003] The use of insect viruses as biological insecticides to control agricultural and forestry pests is a...
