Abstract

The invention provides a trapping agent for Stethynium empoascae Subba Rao and Schizophragma parvula Ogloblin and application thereof, and belongs to the field of plant protection. According to the invention, linalool, methyl salicylate, trans-2-hexenal, perillene and E-beta-farnesene are proportionally prepared into the trapping agent, and the trapping agent has a remarkable trapping effect on the anagrus cicadae and the charomycopsis minuta. The two kinds of anagrus bees are egg parasitic wasps of Empoasca flavescens F. which are important pests in a tea garden, the perennial parasitic rate can reach 5%-75%, and the anagrus bees are rich in resources. A trapping core loaded with the trapping agent is placed between tea tips for slow release, and can trap and guide the two kinds of anagrus bees to search and parasitize Empoasca flavescens F. eggs. The trapping agent is used in the first ten days of August, the trapping core is replaced once every half month until December, a large number of anagrus bees can be continuously trapped in the tea garden to inhabit, parasitize and multiply, leafhopper population declines in a gradient mode from September to December, and parasitize Empoasca flavescens F. population declines remarkably from the middle ten days of May to July in the next year, so that chemical pesticide application is reduced and avoided.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to an attractant for the leafhopper and the tiny rift wasp and its application. The insect attractant is used to lure and guide the leafhopper and the tiny wasp. The rift wasp searches for and parasitizes the eggs of the tea leafhopper. Background technique [0002] The tea green leafhopper Empoasca flavescens F. is the most serious pest in tea gardens in my country, and it has been mainly controlled by pesticides for decades. It has many generations every year, strong fecundity, and strong drug resistance. It reduces tea production by 10%-15% all the year round, and reduces tea production by more than 50% in serious occurrence years. In particular, chemical pesticides are prohibited in organic tea gardens, but this pest occurs seriously, which limits the development of organic tea in my country. However, the tea garden ecosystem inhabits and reproduces the leafhopper wasp Stethynium...
