Problems solved by technology

However, the larvae of Spodoptera litura mainly feed on the leaves of nearly 300 plants such as sweet potatoes, tobacco, cruciferous and solanaceous vegetables. The leaves of these plants are rich in vitamins and some other nutrients, such as soybean flour and bran. It is difficult to completely replace skin powder, etc. Therefore, we have found in practical applications that when feeding Spodoptera litura with feed formulated with this type of formula, problems such as degeneration of insect species, many deformed pupae, and reduced pupation rate and egg production often occur. It is difficult to reproduce after 5 generations

Abstract

The invention discloses an artificial feed for prodenia litura fabricius and an indoor artificial breeding method of the prodenia litura fabricius. The artificial feed is prepared from 80-200g of cabbage leaf powder, 20-40g of bean pulp powder, 5-15g of beer yeast power, 1-3g of butyl p-hydroxybenzoate, 0.5-2g of potassium sorbate, 5-15g of agar, 0.1-0.2g of inositol, 0.1-0.2g of cholesterol, 1-4g of multivitamin powder and 500mL of water. The semi-artificial feed for the prodenia litura fabricius is prepared from the low-cost cabbage leaf powder, and can meet the nutritional requirement of the prodenia litura fabricius. After the prodenia litura fabricius is fed with the formula provided by the invention, larvae can normally grow and develop and have higher survival rate, and pupae are heavier.

Description

technical field [0001] The invention relates to the field of artificial feeding of insects, in particular to an artificial feed formula and preparation method for Spodoptera litura, and an indoor artificial feeding method for Spodoptera litura. Background technique [0002] Spodoptera litura Fabricius belongs to Lepidoptera, Noctuidae, is an important economic pest, and is also an important screening target for pesticides. Establishing Spodoptera litura strains, optimizing the artificial breeding technology of Spodoptera litura, provides A large number of normally developed and uniform sources of tested insects is the basic work of many studies on the physiology, biochemistry, genetics and toxicology of the insect. Therefore, a large number of artificial breeding of Spodoptera litura has become a very important content. [0003] At present, the commonly used raw materials in the formula of artificial feed for Spodoptera litura mainly include soybean powder, yeast powder, bra...
