Method for controlling living condition of empoasca vitis in tea plantation

Abstract

The invention discloses a method for controlling the living condition of empoasca vitis in a tea plantation. The method includes construction of a volunteer tree house, construction of an avoidance wall and construction of a biological missile control wall for the empoasca vitis. According to the method, based on a chemical mechanism of regulation of the behavior of the empoasca vitis, types and layout of plants in the living condition of the tea plantation are planed and designed rationally, so that a push-pull mode between the empoasca vitis and natural enemies of the empoasca vitis in the tea plantation is achieved, the population number of the empoasca vitis is controlled effectively, and a long-term, reasonable and stable eco-community structure and a long-term and effective natural ability of species regulation in the tea plantation are formed in the tea plantation; in addition, zero application of chemical pesticide in the tea plantation can be achieved really, exceeding pesticide residues in tea can be avoided, and levels of the quality and safety of the tea are improved greatly.

Description

technical field [0001] The invention relates to the technical field of pest green prevention and control, in particular to a method for habitat prevention and control of the false-eyed green leafhopper in tea gardens. Background technique [0002] In nature, plants mainly show their identity to the surrounding organisms by releasing volatile organic compounds. The volatile substances form the olfactory signal response of insects to select hosts through insect olfactory receptors, thereby forming insects’ stimulation induction to hosts and non-hosts, forming insects. Host plant selection behavior. Based on this principle, the "habitat management strategy" of integrated pest management has been formed, that is, the change of crop layout can induce the adjustment of the population structure of farmland habitat organisms, especially the adjustment of the species and quantity of target pests and natural enemies, so as to achieve the dynamics of pest population density in the fiel...

AI Technical Summary

Problems solved by technology

[0003] False-eyed green leafhopper is the hardest-hit area of ​​tea production. There are many existing chemical control, physical control and biological control measures, but the control efficiency is low, the persistence is short, the cost is high, and there is no ecological and economical. integrated measures

Although there are some research reports on the selection of hosts and tropism of Leafhoppers (Guo Huifang et al., 2010; Zhang Zhengqun, 2013; Zhang Juewan et al., 1994), and the influence of tea plantation vegetation on the natural enemies of Leafhoppers (Mu Dan, 2011 ; Li Huiling et al., 2016), but these reports are limited to a certain period of time or a certain type of vegetation on the study of Leafhopper and natural enemies
