[0066] On September 26, 2020, in the tea area of ​​Songyang County, Zhejiang Province, during the blooming period of small green leafhoppers, a leafhopper was selected for serious damage to the tea garden and divided into 3 areas: one is the test area for marigold odor repellent, the other It is the test area of ​​marigold odor repellent slow-release agent, and the other is the CK area. The leafhopper population survey in each area was completed before 9:00. That is, five-point sampling was conducted in each area, and the number of leafhoppers on 100 tea shoots was randomly investigated at each point. On September 28, September 30, October 6, and October 8, the same investigation was conducted four times.

Abstract

The present invention provides a marigold odor repellant and trapping method for trapping and killing tea leafhoppers, and marigold is prepared by combining alpha-pinene, naphthalene, gamma-molerene and (+)-4-carene in proportion Odor repellent. Tea green leafhopper is an important pest of tea trees. It damages the buds of tea trees used to make high-grade tea, and likes to inhabit tea bushes most of the time. During the peak period of the leafhopper, the repellant is loaded on the rubber head to make a repellent core, which is attached to the tea branches in the tea bush, and the slow-release repellent drives away the leafhopper and makes it escape from the tea bush; A square bud green insect-attracting sticky board is placed on the tea tree canopy face of the repellent core, and the lower edge is close to the tea tree bud tip; a large number of leafhoppers escaping from the tea bushes are then trapped and killed on the bud green board. After loading the repellent on each lure, add 20-40 μl of liquid paraffin as a slow-release agent, which can prolong the half-life of the repellent effect for several days. This leafhopper repellent can be used for the harmless control of tea leafhoppers. Reduce the use of chemical pesticides.

Description

technical field [0001] The invention belongs to the field of plant protection, and relates to the use of insect pheromones to repel, trap and kill important insect pests, the green leafhopper. In May-July and September-November, when the small green leafhoppers bloom, fix the repellent core on the tea branch in the tea bush, and hang the bud green insect-attracting sticky board on the surface of the tea canopy directly above the repellent core. The bottom edge is slightly higher than the tea bun noodles. The repellent emitted by the repellent core repels the tea leafhoppers in the tea bushes, and the tea leafhoppers tend to bud green insect traps to be trapped and killed, thereby greatly reducing the tea leafhopper population in the tea garden, reducing chemical control and protecting Tea garden environment. Background technique [0002] The tea leafhopper, Empoasca flavescens F., is the most serious pest and disease in tea areas in my country. It sucks the shoots of tea t...
