Abstract

The invention discloses an iragoides fasciata moore sex attractant. The sex attractant comprises 10-20% of 4-methyl-ethyl ester, 23-36% of cis-11-hexadecenol acetate, 5-12% of ethyl 2-hydroxy-4-methylvalerate, 2-8% of 3-methoxy-3-methyl-1-butanol, 2-5% of butylcarbanyl anisole, 2-6% of 2,6-di-tert-butyl p-phenol and the balance of solvents. The sex attractant is prepared through tests in laboratories and repeated tests in forests. When being used for either observing and predicting insect pest situations or trapping in quantity or mating disruption, the sex attractant is beneficial for protecting natural enemies, avoids using chemical pesticides, is environment-friendly and safe, is convenient to use, is low in cost, has long validity, can achieve the aim of effectively controlling iragoides fasciata moore and has obvious ecological and economic benefits.

Description

technical field [0001] The invention relates to insect pheromones, in particular to a sex attractant for tea gnat moths. Background technique [0002] Tea moths belong to the order Lepidoptera, and there are dozens of species that damage tea trees.
