Abstract

The invention provides a method for releasing parasitic wasps of Chilo suppressalis larvae. The method is characterized by comprising a device for releasing parasitic wasps. The device comprises two ends of a wasp carrying body are covered by 10 mesh cellular nylon nets (90), the length of an effective wasp carrying position is 20 cm, width is 10-12 cm. The wasp carrying body is internally placed with a plurality of transparent plastic pipes (20) with bee cocoons, wherein the wasp carrying body is on a floating body. Through the method, large quantity of parasitic wasps of Chilo suppressalis larvae have been successfully released in a large scale manner, labor investment is greatly reduced, and release efficiency of the Chilo suppressalis larva parasitic wasp cocoons is improved.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and is a new method for continuously collecting the parasitic wasps of the larvae of the stem borer indoors and releasing the parasitoids of the larvae of the stem borer in the field. Background technique [0002] With the adjustment of agricultural industrial structure and higher economic benefits, planting Zizania has become an important way for farmers to get rich. There are large areas of Zizania planted in many rice areas, and Zizania field has become the most closely related non-paddy field habitat. The planting mode of rice and wild rice stems has made the occurrence and damage of pests more complicated, and has brought many new problems to the pest control work. Chilo suppressalis Walker belongs to Lepidoptera Lepidoptera Pyralidae, complete metamorphosis insects. It is an important borer and omnivorous pest in the production of rice and wild rice, which seriously endangers the ...
