Large-scale breeding method for breeding mummified aphids and adult bees of aphidiusgifuensis by yellow-green myzuspersicae

Abstract

Disclosed is a large-scale breeding method for breeding mummified aphids and adult bees of aphidiusgifuensis by yellow-green myzuspersicae. The yellow-green myzuspersicae with large bodies serve as host aphids of aphidiusgifuensis, and parent aphid disease-resistant leafy cruciferous green vegetables, radishes or sweet blue flowers serve as host plants of the yellow-green myzuspersicae, so that the mummified aphids and the adult bees of the aphidiusgifuensis are artificially bred on a large scale. The method solves the problems that the bodies of the host aphids are small, the mummified aphids are difficultly collected, the eclosion rate of the aphidiusgifuensis is low, successful egg laying amount is small and industrialized production is not easily realized when the aphidiusgifuensis is artificially bred. Collecting and breeding technology of the host aphids and species of the aphidiusgifuensis is provided in the artificially breeding process, the technology of host plant cultivation, inoculation breeding of the aphids and breeding of the mummified aphids and the adult bees of the aphidiusgifuensis is provided, the method has the advantages of short period, high efficiency, high breeding speed and low cost, the mummified aphids of the aphidiusgifuensis can be largely bred, the mummified aphids and the adult bees of the aphidiusgifuensis are produced on a large scale, and the myzuspersicae, English grain aphids and cotton aphids can be effectively prevented in the technical field of biological prevention.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a large-scale propagation method of using a yellow-green type of aphid to propagate aphids and adult bees in the process of biological control of aphids. Background technique [0002] Aphids persicae is a parasitic wasp, which is often used for biological control of various aphids in agricultural production. In the process of controlling aphids with the use of Aphids persicae, it is necessary to obtain a large number of dead or adult bees of A. In areas where the damage is serious, the Aphididae lays eggs in the body of the aphid, and the eggs of the Aphidias parasitize in the body of the aphid and develop by consuming the nutrients of the aphid, and finally eliminate the aphid. When artificially propagating the dead or adult bees of A. persicae, people usually use the red type A. persica as the host aphid of A. persicae. The individu...

AI Technical Summary

Problems solved by technology

Therefore, the bred aphids of A. persicae are also relatively small, the eclosion rate of A. persicae is low, the lifespan is short, it is difficult to collect, and the collection efficiency is very low; at the same time, because the growth cycle of the host plant tobacco is long, it is difficult to cultivate in winter. The energy consumption is high, and the quality of the obtained Aphidia persicae is also relatively poor, which is not conducive to the large-scale reproduction of A. persicae
