Abstract

The invention discloses an attractant for tea-seed weevil. The attractant is prepared from the following components: schizonepeta lactone, schizonepeta alcohol, cis-3-hexene-1-ol, honeysuckle flower powder, 2, 6-di-tert-butyl-p-cresol, 2-hydroxy-4-methoxybenzophenone, n-pentadecane and ethanol. According to the attractant disclosed by the invention, a botanical attractant and a sex attractant arereasonably matched to obtain a cooperative technical effect and have the significant trapping and killing; and moreover, the attractant has the advantages of being simple in use method, efficient in trapping and killing, environmentally friendly, long in use period and the like, the use amount of pesticide can be greatly reduced when the tea-seed weevil is prevented and controlled, the damage rateof oil-tea camellia fruits is reduced, green production of oil-tea camellia is facilitated, and the quality of the oil-tea camellia is improved.

Description

technical field [0001] The invention relates to the technique of disinsection in commercial forest trees, in particular to an attractant for tea seed weevils. Background technique [0002] Tea seed weevil Curculio chinensis Cheveolat belongs to the family Curculionidae and is the main borer pest of camellia oleifera. It is the dominant species in the main planting areas of camellia oleifera in my country and has been identified as a forestry quarantine pest by the State Forestry Administration. Tea seed elephants produce one generation every two years, but due to their irregular generations, they occur every year, causing a large number of Camellia oleifera fruit drop. Camellia oleifera can harm Camellia oleifera in two ways: adults ingest seed juice and cause severe fruit drop; larvae of tea seed weevil ingest seed kernels of oleifera fruit, causing fruit drop. Tea seed weevil occurs in a large area in Camellia oleifera production areas in my country, which not only causes...
