Method for biologically preventing and controlling micromelalopha troglodyte by using tetrastichus nigricoxae yang

Abstract

The invention discloses a method for biologically preventing and controlling micromelalopha troglodyte by using tetrastichus nigricoxae yang and belongs to the technical field of forest conservation and biological prevention and control. The method comprises the following technical steps of (1) collecting and preserving bees; (2) selecting and preserving substitutive hosts; (3) breeding the tetrastichus nigricoxae yang; (4) rejuvenating the bees; (5) releasing the tetrastichus nigricoxae yang; and (6) continuously controlling the micromelalopha troglodyte. The method is simple and convenient to operate and efficient in system, excellent bred bees are selected to substitute the hosts, the technical problem of artificial scale bee breeding is solved, an appropriate bee releasing technology is researched, and the preventing and controlling effect is remarkable. The bees are ordinarily released for three times in a low micromelalopha troglodyte population period to prevent and control a next generation of micromelalopha troglodyte pupas, injurious insects can be basically controlled, and a full-year disaster-free and insect-existing control target is achieved.

Description

technical field [0001] The present invention relates to a method for the biological control and control of Pyrethia spp., which belongs to the technical field of forest protection biological control, and more specifically relates to a method for using the parasitic natural enemy insect, P. A new method for small bees to control forestry pests. Background technique [0002] At present, only Trichogramma, Scleroderma guanidei and ladybugs have achieved large-scale reproduction and release of natural enemy insects in my country, but these natural enemy insects are mainly used to control pest eggs and larvae, and most of them are used in the control of agricultural pests. The only parasitic wasp that has been successfully used in the prevention and control of the pupal stage of pests is the invention patent of CN1511450A, which discloses a method for biological control of white moth Chouioia cunea Yang by using tussah silkworm pupae to reproduce the white moth Chouioia cunea Yang...

Problems solved by technology

[0002] At present, only Trichogramma, Scleroderma guanidei and ladybugs have achieved large-scale reproduction and release of natural enemy insects in my country, but these natural enemy insects are mainly used to control pest eggs and larvae, and most of them are used in the control of agricultural pests. The only parasitic wasp that has been successfully used in the prevention and control of the pupal stage of pests is the invention patent of CN1511450A, which discloses a method for biological control of white moth Chouioia cunea Yang by using tussah silkworm pupae to reproduce the white moth Chouioia cunea Yang. Parasitic wasp is used to prevent and treat the parasitic effect of Yang Xiaozhou moth relatively poorly, and main reason is that this bee and the white moth black base of the present invention belong to the different genus and species of the subfamily of Bacteridae in classification, both individual form and parasitic Large performance difference

At the same time, the use of the white moth black base gnat to biologically control Yang Xiaozhou moth is a system that includes multiple technical elements such as collection of excellent seed bees, large-scale reproduction of bee alternative host screening, preservation, reproduction, rejuvenation, release control and continuous control. technology, currently there is no such technology in the control of Yang Xiaozhou moth in China
