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

A technology based on gnats and gnats, which is applied to the field of biological control of the white moth black-based gnats, and forestry pests. It can solve the problems of large differences in individual morphology and parasitic performance, and poor parasitic effects. Achieve the effect of solving a large number of artificial bee breeding, easy operation, and controlling the harm of summer pests

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

Embodiment Construction

[0019] The methods and effects of the present invention will be further described below in combination with embodiments.

[0020] (1) Collection and preservation of bee species: in the overwintering pupae stage of the moth, the pupae of the moth are collected and reared to obtain the species of bee. The characteristics of the pupae of Yang Xiaozhou moth parasitized by wasps are: the pupae is light in weight, dark in color and dull; the intersegmental membrane is elongated and cannot be retracted; the pupae shell is thin and fragile. According to the above-mentioned characteristics, the parasitic pupae are selected from the pupae of the moth Yang Xiaozhou collected, and the adult bees of the white moth black-base gnats can be bred. The pupae of the moth, which contained mature larvae of wasps collected in winter, were stored at -5°C. Before multiplying the bees, take them out and place them indoors at a room temperature of about 25°C until they emerge.

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...
