A kind of sex attractant and lure core

Abstract

The invention relates to the technical field of insect lures, in particular to a sex lure and a lure core for the small-horned wood beetle moth. The sex lure of the small horn beetle moth includes the active ingredient of the sex attractant, and the active ingredient of the sex attractant includes cis-3-tetradecenyl acetate, trans-3-tetradecenyl acetic acid esters and cis-5-dodecenyl acetate. The sexual attractant for T. chinensis provided by the present invention is beneficial to the protection of T. sclerosus no matter whether it is used for insect situation forecasting, direct hunting by trapping method, or interfering mating method to prevent and control T. The natural enemies of moths, benefit and eliminate pests, give full play to the power of preventing and controlling wood beetle moths, improve the effect of preventing and controlling wood beetle moths, and can also avoid the use of chemical pesticides, reduce pollution, protect the environment, and its social benefits and Significant ecological benefits.

Description

technical field [0001] The invention relates to the technical field of insect lures, in particular to a sex lure and a lure core for the small-horned wood beetle moth. Background technique [0002] Streltzoviella insularis (Staudinger) belongs to Lepidoptera (Lepidoptera) Cossidae. It is an important dry borer pest in my country. It mainly damages ash, ginkgo, Chinese pagoda tree, elm and paper tree with its larvae. , the number of insects per plant can reach hundreds, and it has occurred in large areas in Beijing, Tianjin, Hebei, Jiangsu, Jiangxi, Hunan, Shanghai and other provinces and cities. The prevention and control brings great difficulties, leading to a significant reduction in the use value, aesthetics and protection efficiency of forest trees, which seriously threatens ecological construction and economic development. [0003] After many insects mature, they can emit chemical substances outside the body to attract insects of the opposite sex to mate with them. The c...

Problems solved by technology

To study insect sex attractants, it is necessary to understand the structure and proportioning rules of specific insect species. For example, the sex pheromone components of the insect moth family include cis-3-tetradecenyl acetate, trans-3-tetradecenol Enol acetate, cis-3-trans-5-tetradecenyl acetate, cis-5-tetradecenyl acetate, cis-5-dodecenyl acetate, cis -7-tetradecenol acetate, cis-9-tetradecenol acetate, trans-3-tetradecenol, cis-3-tetradecenol, cis-7-decenol The chemical structure of its main components is 14-carbon straight-chain enol or its acetate. Although one or two of different types of pheromone components are completely the same, the coordination between types Compared with completely different, such as the sex attractant of seabuckthorn wood beetle, the sex attractant of sandbuckthorn wood beetle, the sex attractant of salix wood beetle, the sex attractant of elm wood beetle, etc. have been successfully developed and widely used. However, up to now So far, there is still no report on the method of effectively trapping the beetle moth
