Problems solved by technology

[0006] At present, gypsy moth virus (preferably nuclear polyhedrosis virus) is the most economical to replicate in gypsy moth larvae. Although the artificial breeding technology of gypsy moth has been successfully solved, due to the high cost of feeding, it has seriously inhibited the large amount of gypsy moth virus in the wild.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited to the examples.

[0032] 1. Preparation of artificial diet and its effects on growth, development and survival of gypsy moths

[0033] 1. Preparation of artificial feed

[0034] The artificial feed of the present invention is prepared by mixing the following components: Webster's salt 8g, wheat germ 120g, casein 50g, sucrose 10g, sorbic acid 2g, ascorbic acid 8g, choline chloride 2g, inositol 2g, cholesterol 3g, agar 15g, 780ml water;

[0035] Adopt following feed as comparative example:

[0036] Feed ①: Casein 35g, Webster's salt 10g, sucrose 12g, fructose 23g, wheat germ 60g, choline chloride 1g, p-hydroxyl 1.5g, agar 25g, aureomycin 0.3g, ascorbic acid 4g, 4M KOH 5ml, 38 % formaldehyde 0.5ml, 55% linolenic acid 4.3ml, mixed vitamins 10ml (niacin 100g, calcium pantothenate 100g, riboflavin 50g, thiamine hydrochlor...

Abstract

The invention relates to a production process of a gypsy moth nucleopolyhedrosis virus insecticide. The invention provides an artificial gypsy moth feed at a low price; and the gypsy moth fed by the feed has weight, developmental duration, and survival rate similar to that fed by a natural feed, so as to improve yield of the gypsy moth virus, reduce production cost, and expand the application area in the field. The technology for production of gypsy moth virus insecticide through the artificial feed is not restrained by external environment, and is suitable for large-scale production; and the prepared pesticide is safe and efficient.

Description

technical field [0001] The invention relates to a low-cost gypsy moth artificial feed, which is used for producing gypsy moth virus insecticide, and belongs to the forest pest-gypsy moth biological control field. Background technique [0002] Lymantria dispar L., also known as swing caterpillar, apple poisonous moth, persimmon caterpillar, belongs to Lepidoptera Lepidoptera, Lymantriidae family Lymantriidae, Lymantria is a worldwide leaf-eating pest, with wide distribution, miscellaneous feeding habits, harmful Heavy, larvae migrate with the wind and so on. [0003] Due to the serious harm of gypsy moth to agriculture and forestry, people have adopted various methods to control gypsy moth in the past hundred years. Chemical pesticide control is the earliest and most widely used control method so far. Because of its economical, effective, simple method, and no terrain restrictions, when forest pests occur, satisfactory control effects can be achieved in a short period of ti...
