Artificial assisted mating and rearing method of Huashan pine beetle

Abstract

In the present invention, holes are drilled on the side of the Huashan pine section to the xylem, and inserted into the sandy soil of the flower pot; the female Huashan pine beetle is put into a transparent capsule and embedded in the hole drilled in the wood section, and the flowerpot is placed in a dark room; After confirming that the female insects invaded the Huashan pine section, the transparent capsules were taken out, and the transparent capsules put into the male insects were inserted into the holes; after observing and confirming that all the male insects had invaded, the flower pots were removed from the darkroom for cultivation, and watered to keep the bark moist until the second day. Daihuashan pine beetles emerged and flew. The present invention solves the problem of difficult indoor subculture breeding of the Huashan pine beetle, can continuously provide insect sources for the prevention and control research of the Huashan pine beetle, and shortens the scientific research period. Most of the second-generation Huashan pine beetles are in the larval stage of different ages. After 75 days of successful mating, adults will gradually fly away, and the success rate of male and female mating is 75%.

Description

technical field [0001] The invention relates to an artificially assisted mating and raising method, in particular to a method for artificially assisting mating and raising of the Huashan pine beetle, and belongs to the field of plant protection. Background technique [0002] Bark beetles are a serious pest in forest areas. At present, more than 6,000 species are known in the world, and there are more than 500 species in China. 70% of bark beetles harm the phloem and xylem of coniferous trees. The stage is hidden under the bark, and there is only a short-term flying and spreading in the adult stage. Due to the unique life history and hazard characteristics of bark beetles, it greatly increases the difficulty of management. [0003] The Huashan pine beetle belongs to the Coleoptera (Coleoptera) Scolytidae (Scolytidae) genus ( Dendroctonus ), is a kind of bark beetle that is more harmful. It is mainly distributed in Shaanxi, Sichuan, Gansu, Henan and other places in my countr...

Problems solved by technology

[0004] In order to prevent and control the Huashan pine beetle more effectively, it is necessary to conduct in-depth research on the survival, breeding and harm of the Huashan pine beetle. However, because the short adult period of the Huashan pine beetle is a time barrier for the research, artificial assisted mating is required. Control research continues to provide insect sources, and shortens the research period for the prevention and control of Huashan pine beetle through subculture breeding of Huashan pine beetle. It can only raise the Huashan pine beetle from larvae to adults, and it is still impossible to use culture medium and artificial feed for subculture in the room. There are no relevant literature reports on the subculture method of Huashan pine beetle. If it can be effectively The subculture of the Huashan pine beetle indoors will buy more time for the research of the Huashan pine beetle, which is conducive to the effective prevention and control of the Huashan pine beetle
