American white moth artificial breeding and propagating method

Abstract

A kind of artificial feeding and subculture method of American white moth, the method is as follows: 1) routinely sterilize the eggs of American white moth; put into a healthy insect breeding room to raise; the components of the feed and their weight percentages are as follows: germ 5-12; sucrose 2-5; protein 3-7; Webster's salt 0.3-1; sorbic acid 0.4-1.2 ; methyl p-hydroxybenzoate 0.1-0.5; ascorbic acid 0.02-0.19; vitamin B 0.03-0.15; agar 1.1-1.8; cholesterol 0.05-0.16; water 75-85; , eclosion of adults at room temperature and removal of diapause; 4) matching the male and female adults after eclosion into a pair, and putting them into the adult oviposition room for mating and oviposition. Among them, the room temperature for adult eclosion and release of diapause at room temperature is 25 degrees, and the cleanliness of the healthy insect breeding room should be 1,000 degrees, and the room temperature should be kept at 22-25 degrees. It is not restricted by the external environment, and can provide sufficient insect sources for the large-scale continuous production of safe and efficient biopesticides.

Description

technical field [0001] The invention relates to a method for artificial breeding and subculture of the white moth. Background technique [0002] The American white moth (Hyphanlria cunea) is a devastating pest and has been listed as an international quarantine object. Domestically distributed in Liaoning, Shandong, Tianjin, and parts of Shaanxi and Hebei, they are currently threatening Beijing directly. The American white moth has a very mixed diet, mainly harming fruit trees, street trees, ornamental trees and other broad-leaved trees and crops. There are more than 100 kinds of broad-leaved trees in the United States; 230 species of plants in Europe; and 317 species in Japan. Only in the occurrence area of ​​American white moth in Liaoning Province, my country, more than 100 kinds of plants were damaged, and sugar maple, ash, mulberry, and cherry trees were the most affected trees, followed by poplar, willow, sycamore, clove, elm, five-leaf maple, Larix, etc.; apples, hawt...

AI Technical Summary

Problems solved by technology

[0006] To produce the insecticide against the NPV, a large number of larvae must be raised to reproduce the virus. At present, natural feeds are mostly used in the wild, which will be restricted by many external environmental factors, such as: climate, region, and insect population. Density, tree height, terrain, etc. will directly affect the growth and generation of the American white moth. Since the American white moth survives the winter in the wild for about 6 months, it cannot reproduce continuously and it is difficult to carry out large-scale production.
