Artificial propagation method for myzus persicae

Abstract

The invention particularly relates to an artificial propagation method for myzus persicae, which belongs to the technical fields of insect breeding and propagation. The method comprises the steps of choosing a myzus persicae sensing tobacco variety, raising seedlings, transplanting, choosing myzus persicae, inoculating the myzus persicae and propagating the myzus persicae. According to the artificial propagation method, the propagation time and the propagation quantity of the myzus persicae can be adjusted flexibly according to practical requirements of tests or researches; different requirements of the myzus persicae under different conditions are met; and the method is simple to operate and uses little time and few labors.

Description

technical field [0001] The invention belongs to the technical field of insect feeding and breeding, and in particular relates to an artificial breeding method of aphids. Background technique [0002] The tobacco aphid, also known as the green peach aphid, is a worldwide pest, which commonly occurs in our country and causes serious damage. There are more than 300 species of host plants for aphids, and their favorite hosts include tobacco, potatoes, cabbage, rapeseed, cabbage and other vegetables, as well as peach trees and other forest trees. The damage of tobacco aphid includes two aspects: direct damage and indirect damage. The direct damage mainly refers to the adult and nymph sucking the plant juice and affecting the normal growth and development of the plant; . [0003] However, Aphis persicae is a commonly used experimental material, which can be used as a bioassay material for screening pesticide varieties, and is often used in entomological research. [0004] For a...

Problems solved by technology

However, due to the obvious seasonality of the growth of host plants, the occurrence of aphids in the host growing season is affected by various factors such as climate and environment. It is difficult to ensure the consistency and quantity requirements of the tested aphids by field collection methods.

However, using conventional potted host plants to propagate aphids in the greenhouse requires a large number of flowerpots and nutrient soil, which takes up a lot of space, requires frequent watering, and requires a lot of labor. Once the host plants lack water, it is easy to cause wilting and affect the number of aphids.
