Abstract

The invention belongs to the technical field of biological control over agricultural pests and particularly relates to a method for breeding male encarsia sophia by using trioxysrietscheli. The methodcomprises the steps of culturing a host plant cotton; culturing primary hosts bemisia tabaci and aphis gossypii; culturing secondary hosts; preparing female parents of encarsia sophia; breeding maleencarsia sophia. The method achieves the purpose of rapidly producing male encarsia sophia under the condition that there are few inset breeding chambers and the population number of bemisia tabaci ina field and specific parasitic wasps thereof is small, the mass propagation of encarsia sophia before the peak period of bemisia tabaci is thus realized, and the method is used for biological controlover bemisia tabaci.

Description

technical field

[0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for breeding drones of A. Background technique

[0002] Whitefly Bemisia tabaci (Gennadius) is a very serious worldwide pest. There are more than 600 species of host plants, and it can carry more than 70 plant viruses. It is seriously harmful to cotton, vegetables and flowers in my country. The wasp Encarsia sophia is the main parasitoid of Bemisia tabaci, and it is distributed in both southern and northern my country. The bee belongs to the order Hymenoptera, Aphididae, and the genus Aphididae. It is a monoparasitic endoparasitoid and has a unique facultative autoparasitic reproductive mode, that is, the female bee is a primary parasitoid and parasitizes on the primary host. Bemisia tabaci nymphs, while drones are polyparasitoids, which parasitize on the same or heterogeneous parasitoid larvae of the secondary host. Under n...
