Problems solved by technology

In addition, when the authorized attractant is used, it needs to be placed on the surface of the tea tree to attract weevils and then taken off the field, so there are certain limitations in the actual use process
In summary, there is currently a lack of effective and simple control measures for Chaliweevil in the field

Abstract

The invention discloses a contact pheromone-based attractant for male adult beetle weevils, which belongs to the technical field of using chemical information substances for green prevention and control of pests. It includes the following components in parts by weight: cis / trans-ocimene 1-100, cis-3-hexenyl acetate 0.06-6, n-pentacane 0.01-1, 2,6-di-tert-butyl p-cresol 0.001-0.02, 2-hydroxy-4-methoxybenzophenone 0.001-0.02. The male adult attractant for the weevil weevil of the present invention is particularly suitable for popularization and application to tea farmers, has remarkable economic, social and ecological benefits, and has broad industrialization prospects.

Description

technical field [0001] The invention belongs to the technical field of pest green prevention and control by using chemical semiotic substances, and in particular relates to an attractant for adult male weevil weevil weevils based on pest contact pheromones. Background technique [0002] Tea weevil Myllocerinus aurolineatus Voss belongs to Coleoptera, Weevilidae, Limulus genus, also known as tea weevil (tea limulus), is one of the main leaf-eating pests in tea areas in my country, with one generation per year and overwinters as pupae.
