Abstract

The invention discloses a method for propagating sulzer braconid flies. The method comprises the following steps: firstly, culturing a host plant of tobaccos, then propagating sulzers and afterwards propagating the sulzer braconid flies by the sulzers. By propagating the flies in batches, the multi-generation repeated propagation of the sulzer braconid flies is avoided, the generation quantity ofthe hyperparasite flies of the sulzer braconid flies is reduced, and the survival capability of the sulzer braconid flies in the field is enhanced. The propagation time and quantity of the sulzer braconid flies can be flexibly regulated and controlled according to the actual condition of the field, and different requirements on the sulzer braconid flies under different situations are met. The emergence rate of the stiff aphids of the sulzer braconid flies propagated by the invention is more than 90%, the male-female ratio is 0.8-1.0:1, and the utilization rate of the stiff aphids or the adultflies is more than 80%.

Description

technical field

[0001] The invention belongs to the technical field of biological control of diseases and insect pests, and relates to the utilization of natural enemy insects, in particular to a method for multiplying Aphids aphids. Background technique

[0002] In recent years, the application of natural enemy insects has developed rapidly at home and abroad. The reproduction and release of Trichogramma and predatory mites have become a model for the use of natural enemy insects in my country. The use of natural enemy insects has developed into an important measure for crop pest control in modern agriculture. Apidius gifuensis Ashmead (Apidius gifuensis Ashmead) is an endoparasitic wasp specialized in parasitizing aphids and an important parasitic natural enemy of aphids. The natural parasitism rate of Aphidia persicae to A. persicae is usually between 20% and 60%, and can reach 89.16% at the highest [Zhao Wanyuan, Ding Chuiping. Research on the biology and application of ...
