Artificial breeding and production method of pupal parasitoid for enhancing the biological control effect of fruit flies

Abstract

The invention relates to the field of agricultural pest biological control and aims at providing a pupal parasitized wasp artificial breeding production method capable of enhancing drosophila biological control effects. The method comprises collecting drosophila melanogaster pupas with parasitized trichopria drosophilae perkins, performing eclosion for continuous three generations for parasitizing drosophila hydei pupas, and collecting wasp species; inoculating and breeding drosophila hydei, parasitizing and breeding the drosophila hydei pupas with queen parasite wasps, and collecting hatched parasite wasps for storage and reservation. The pupal parasitized wasp artificial breeding production method capable of enhancing the drosophila biological control effects controls the parasite time of the trichopria drosophilae perkins during production and inoculation processes, avoids low parasitic rate caused by over-short parasite time or low yield rate caused by excessive parasitism, facilitates reasonable inoculation and utilization of the parasite wasps through cultivation of the trichopria drosophilae perkins, is applicable to large-scale continuous production, optimizes dominant host selection and wasp breeding technology, achieves high-quality, efficient and large-scale propagation of the trichopria drosophilae perkins and lays a good foundation for propagation and utilization of the trichopria drosophilae perkins.

Description

technical field [0001] The invention relates to the field of biological control of agricultural pests, in particular to a production method for the artificial breeding of pupal parasitoids that enhances the effect of biological control of fruit flies, and belongs to the artificial breeding method of dominant hosts and the artificial breeding of pupal parasitoids for enhancing the biological control effects of fruit fly pests production method. Background technique [0002] Drosophila has a wide range of feeding habits and a special growth environment. It likes dark and humid habitats. It has obvious tropism for sweet and sour and putrid odors. It can damage a variety of fruits and vegetables and the succulent organs of many plants. It is an important agricultural pest. When fruit flies harm crops, they usually exist in the form of mixed species, including Drosophila melanogaster, D. immigrans, and D. suzukii. Parasitic wasps can control the population of hosts and are impor...

Problems solved by technology

At present, there is no research report on the large-scale propagation and application of S. trichomes in the country and its application to the control of fruit fly pests. If the large-scale propagation of S. trichomes can be carried out on a large scale, it will improve the effect of pest control in actual production has important reference significance
