Abstract

The present invention discloses a beet armyworm sex pheromone composition and a beet armyworm sex pheromone lure, wherein the beet armyworm sex pheromone composition comprises three components such as cis-9,trans-12-tetradecadienyl acetate, cis-9-tetradecenylalcohol and tetradecenal according to a mass ratio of 80:10:10-200, and the beet armyworm sex pheromone lure comprises the beet armyworm sex pheromone composition and a releaser for holding and slowly releasing the beet armyworm sex pheromone composition. According to the present invention, the beet armyworm sex pheromone composition and the beet armyworm sex pheromone lure have strong specificity for male beet armyworm, and do not trap and kill female beet armyworm and other insects; and with the beet armyworm sex pheromone composition and the beet armyworm sex pheromone lure, the high-incidence season of the pest generation can be effectively monitored, the blind pesticide spraying can be avoided, the good prevention control effect is provided, and the natural enemies of pests can be effectively protected and used.

Description

technical field [0001] The invention relates to a substance for preventing and controlling beet armyworm, in particular to a sex pheromone composition of beet armyworm and a lure made from the sex pheromone composition, belonging to the technical field of biological control of beet armyworm. Background technique [0002] Beet armyworm Spodoptera exigua Hiibner (Beet armyworm) commonly known as cabbage brown armyworm, belonging to Lepidoptera, Noctuidae, is a worldwide distribution, intermittent large-scale omnivorous pests mainly harmful to vegetables.
