Artificial feed for American white moth larvae and preparation method of artificial feed

Abstract

The invention discloses an artificial feed for American white moth larvae and a preparation method of the artificial feed. The artificial feed is prepared from the following raw materials in percentage by mass: 10-16% of sweet potato residues, 15-20% of enteromorpha dry powder, 0.3-0.5% of a Webster's salt, 0.2-0.5% of potassium sorbate, 0.4-0.8% of choline chloride, 0.05-0.1% of cholesterol, 2.3-2.7% of agar powder and the balance of starch waste liquid. The artificial feed are low in main raw material price; the preparation method of the feed is simple; the obtained artificial feed is mildew-proof and corrosion-resistant and the feeding effect is superior to that of a natural feed; the larvae fed by the feed are healthy and large in quantity; and the targets of annual and continuous rearing and year-round supply of standard worm sources of white moth larvae can be achieved.

Description

technical field [0001] The invention relates to the field of artificial breeding of pests, in particular to an artificial feed for white moth larvae and a preparation method thereof. Background technique [0002] American white moth, also known as American lamp moth, autumn curtain caterpillar, autumn curtain moth, belongs to Lepidoptera, Diligidae, and white moth. It is a worldwide quarantine pest. It mainly harms fruit trees, street trees and ornamental trees, especially broad-leaved trees. It has caused serious harm to garden trees, economic forests, farmland protection forests, etc., and has been included in the first batch of invasive alien species in my country. The American white moth spends the winter as a pupa under the bark of trees or on the dead branches and leaves on the ground. After hatching, the larvae spin silk and form a web, and feed on the leaves in the cluster net. After the leaves are eaten up, the larvae move to another part of the branch and twig to...

AI Technical Summary

Problems solved by technology

These researches aim at the research work of biological control of white moth, so that the demand for artificially cultivating white moth is increasing year by year. Fresh feed is easy to spoil and deteriorate, causing larval disease and reducing the survival rate. In order to solve the disadvantages of natural feed, researchers have carried out research work on the development of artificial feed for white moth, and developed an artificial feed suitable for white moth larvae. However, the existing artificial Most of the feed uses germ and soybean powder as the main raw materials, and it also needs to add various nutritional additives such as vitamins. The production cost is relatively high, and it cannot effectively reduce the feeding cost of white moths.
