Problems solved by technology

[0003] However, there are two shortcomings in the current fruit fly attractants: first, most of the fruit fly attractant formulations are liquid formulations, which are easily isomerized or oxidized due to the influence of light and temperature conditions, and cannot maintain stable release for a long time second, a single attractant can only lure a single fruit fly, and the same trapping system cannot be used to trap or monitor multiple fruit fly pests at the same time

Abstract

The invention discloses a compound type slow-release trypetid attractant and a preparation method thereof. The compound type slow-release trypetid attractant is prepared from methyleugenol, cue lure,beta-caryophyllene, a paraffin carrier and a cellulose acetate fiber tow, wherein the methyleugenol, the cue lure, the beta-caryophyllene and the paraffin carrier are mixed to fill the cellulose acetate fiber tow. The compound type slow-release trypetid attractant disclosed by the invention has a wider attracting range; the preparation method has the advantages of simpleness, low cost and strong operability; the speed of oxidizing and decomposing the active ingredients in the methyleugenol, the cue lure and the beta-caryophyllene can be reduced, the use amount is greatly reduced, and the methyleugenol, the cue lure, the beta-caryophyllene can be stably and continuously released for at least 12 weeks.

Description

technical field [0001] The invention belongs to the technical field of insect attractants. More specifically, it relates to a composite fruit fly slow-release attractant and a preparation method thereof. Background technique [0002] Fruit fly belongs to Tephritidae, is a herbivorous insect, and its larvae are latent feeding. Among them, Bactrocera dorsalis, Bactrocera melon and Bactrocera guava are the most destructive agricultural pests in the world, seriously endangering the world. The fruit and vegetable production in various places and the restriction of local fruit and vegetable trade export cause serious economic losses every year. The use of attractants methyl eugenol, muscarone and β-caryophyllene to trap and kill males and monitor populations has become an effective technical means to control fruit fly pests. [0003] However, there are two shortcomings in the current fruit fly attractants: first, most of the fruit fly attractant formulations are liquid formulati...
