Abstract

The invention provides an attractant for the leafhopper three-rod tassulae and the tiny rift tassusae and application thereof, and belongs to the field of plant protection. In the present invention, linalool, methyl salicylate, trans-2-hexenal, perillene and E-β-farnesene are proportioned to form an attractant, which is effective against the leafhoppers Triptospora spp. Tsingtae vulgaris has a significant attracting effect. These two species of tassel wereps are the egg parasitoids of the important pest of the tea garden, the green leafhopper. The perennial parasitic rate can reach 5%-75%. The lure core loaded with the attractant is placed between the tea shoots for slow release, which can attract and guide the two species of wasps to search and parasitize the eggs of the green leafhopper. Use the attractant in the first ten days of August, and replace the lure core every half month until December, which can continuously attract a large number of bees to the tea garden to inhabit, parasitize and multiply. From mid-May to July of the following year, the insect population of the tea leafhopper was significantly reduced, thereby reducing the application of chemical pesticides.

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 tassel and its application. The insect attractant is used to attract and guide the leafhopper and the tiny Rift tassel wasps searching and parasitizing the eggs of the tea leafhopper. Background technique [0002] The tea 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 a large number of generations every year, strong fecundity, and strong drug resistance, which can reduce tea production by 10%-15% all year round, and reduce tea production by more than 50% in severe years. In particular, chemical pesticides are banned in organic tea gardens, but the pests are seriously occurring, which restricts the development of organic tea in my country. However, the tea garden ecosystem is home to Stethynium empoascae Subba Rao and Sch...
