Method for realizing three-dimensional propagation of Aphidius gifuensis Ashmaed by means of cuttage plant

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 propagation of Aphids aphids by cutting plants, in particular to a combination of methods such as carrier plant screening, rapid propagation of carrier plant cuttings, module propagation of bees, and collection of aphids. Background technique [0002] Smoke aphid [Myzuspersicae (Sulzer)] belongs to Homoptera, Aphididae. Also known as peach aphid, commonly known as honey worm, greasy worm. Aphids are distributed all over the world, and generally occur in the smoking areas in the north and south of my country. Its feeding habits are relatively miscellaneous, and there are more than 170 species of host plants known in my country. There are more than 400 kinds of hosts in 50 families reported in the world, mainly Solanaceae, Brassicaceae, Compositae and Fabaceae. In addition to directly sucking the plant juice, causing plant water and nutritional imbalance and shrinking, the insect also spreads var...

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
