白星花金龟引诱剂的田间筛选

以危害果树的重要害虫白星花金龟(Potosia brevitarsis)为研究对象,通过近三年的野外观察和室内解剖等实验,就几种引诱剂对白星花金龟的诱集作用进行了研究,旨在为白星花金龟的综合防治提供新的思路。结果表明:30%蔗糖溶液、30%D-果糖溶液、反-2-己烯醛、乙酸丁酯、苯酚等几种物质对白星花金龟有诱集作用。其中,30%蔗糖溶液诱导性最强。

Field Screening of the Attractants for Potosia Brevitarsis

The study object is potosia brevitarsis which is important pests of fruit trees.We studied trapping roles of several attractants for potosia brevitarsis,through nearly three years of field observations and laboratory anatomy experiments.The purpose of the study is providing new ideas to integrated control potosia brevitarsis.The results showed that 30% cane sugar and fructose solutions,E-2-hexenal and butyl acetate,phenol and other substances had the role of luring to potosia brevitarsis.The 30% cane sugar was the best attractant.
