A method for three-dimensional propagation of Aphids aphids by using cutting plants

Abstract

The invention discloses a method for realizing three-dimensional propagation of Aphidius gifuensis Ashmaed by means of a cuttage plant. The method comprises the following steps of 1) cultivating Gynura japonica as a host plant; 2) breeding aphids; 3) breeding the Aphidius gifuensis Ashmaed; and 4) collecting mummy aphids for manufacturing an Aphidius gifuensis Ashmaed egg aggregate. The method has advantages of short period, small space requirement and easy mummy aphid collection. The method can greatly reduce an Aphidius gifuensis Ashmaed propagation cost and can promote large-scale propagation and commercial production of the Aphidius gifuensis Ashmaed.

Description

Technical field [0001] The invention relates to a method for three-dimensional multiplication of Aphididae by using cutting plants, in particular to a combination of methods such as carrier plant screening, carrier plant cutting rapid multiplication, modular multiplication, and dead aphid collection. Background technique [0002] Myzus persicae [Myzus persicae (Sulzer)] belongs to Homoptera, Aphididae. Also known as the green peach aphid, commonly known as honey insects and greasy insects. Myzus persicae is distributed all over the world, and it is common in tobacco areas in north and south my country. Its feeding habits are relatively mixed, and there are more than 170 species of known host plants of Myzus persicae in my country. The world has reported more than 400 hosts from 50 families, mainly Solanaceae, Cruciferae, Compositae and legumes. In addition to directly sucking plant sap, the worm causes plant water and nutrition disorders and shrinks, but also spreads a variety...

AI Technical Summary

Problems solved by technology

[0006] In the practice of propagating Aphids persicae, we found that the above-mentioned technology has certain limitations, mainly as follows: first, the tobacco growth cycle is long, and it often takes more than 90 days from sowing to inoculation of aphids, requiring a lot of manpower and material resources ; Second, the growth of tobacco requires a large space. A single tobacco plant can grow to a height of 2 meters. Tobacco cultivation needs to be arranged at a distance of 1 × 1 meter, and a larger area is required for propagation; third, the tobacco leaves are sticky. It is not conducive to the collection of parasitic bees; fourth, the patent collects bees, which is not conducive to product storage and transportation
