Abstract

The invention discloses a tea seed attractant, which comprises the following components: nepetalactone, nepetalol, cis-3-hexene-1-alcohol, honeysuckle powder, 2,6-di-tert-butyl p-Cresol, 2‑Hydroxy‑4‑methoxybenzophenone, n-pentacosane, ethanol. The attractant of the present invention obtains a synergistic technical effect through the reasonable compatibility of the plant-derived attractant and the sexual attractant, and has a significant trapping and killing ability for tea seed elephants. It can greatly reduce the amount of pesticides used in the prevention and control of tea seed weeds, reduce the damage rate of camellia oleifera fruit, benefit the green production of camellia oleifera, and improve the quality of camellia oil.

Description

technical field [0001] The invention relates to a technology for removing insects in economic forests, in particular to an attractant for tea seed elephants. Background technique [0002] The tea seed elephant, 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 forest quarantine pest by the State Forestry Administration. Tea seed elephants have one generation every 2 years, but due to the uneven generations, it occurs every year, causing a large number of camellia fruit drop. There are two kinds of damages of Camellia oleifera to Camellia oleifera: adults ingesting the juice of the seed kernels cause severe fruit drop; Camellia oleifera larvae ingesting the seeds of Camellia oleifera fruit, causing fruit drop. Tea seed elephants occur in large areas in Camellia oleifera production areas in my ...
