Problems solved by technology

In chemical control, the effect of confusing two kinds of inchworms is not great, and the control effect is basically close, but there are problems when using specific sex pheromones
When the tea caterpillar sex attractant is used alone, it has a good control effect on the tea caterpillar, but the tea caterpillar cannot be effectively controlled, and other measures still need to be taken; when the tea caterpillar sex attractant is used alone, it has a good effect on the tea caterpillar control effect, but the gray tea inchworm cannot be effectively controlled, and other measures need to be taken

Abstract

The invention provides a universal sex pheromone composition and sex attractant for Ectropis grisescens and Euproctis pseudoconspersa as well as a preparation method and application of the sex pheromone composition and the sex attractant. The invention belongs to the technical field of tea pest control. The universal sex pheromone composition is prepared from cis-3, cis-6, cis-9-octadecatriene, cis-3, cis-9-6, 7-epoxy octadecadiene, cis-3, cis-6-9, 10-epoxy octadecadiene, cis-6, cis-9-3, 4-epoxy octadecadiene, 10,14-dimethyl pentadecanol isobutyrate and 14-methyl pentadecanol isobutyrate in amass ratio of (20-70):(30-80):(25-75):(25-75): (60-100):(5-30). The universal attractant disclosed by the invention has strong attractive force on the ectropis grisescens and the Euproctis pseudoconspersa at the same time, and can be used for efficiently carrying out population monitoring and trapping and killing control on the ectropis grisescens and the Euproctis pseudoconspersa.

Description

Technical field [0001] The invention belongs to the technical field of prevention and control of tea tree pests, and particularly relates to a general sex pheromone composition of gray tea looper and tea caterpillar, a sex attractant, and a preparation method and application thereof. Background technique [0002] Grey tea looper (Ectropis grisescens Warren) and tea caterpillar (Euproctispseudoconspersa Strand) are two serious leaf-eating pests of tea trees. Grey tea geometrids are distributed in southern tea areas such as Hunan, Hubei, Jiangxi, Zhejiang, Guangdong and Yunnan, especially in Hunan. The larvae eat a lot of leaves and eat the tea bushes until they are bald when they break out. In addition to tea trees, tea caterpillars also harm a variety of crops such as camellia, citrus, camellia, Chinese tallow, and corn. They are mainly distributed in Shaanxi, Jiangsu, Anhui, Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Jiangxi, Hubei, Hunan, Sichuan and Guizhou. And so on. It...
