桃小食心虫(以下简称桃小),是苹果、梨、桃等果树的主要蛀果害虫,近年来我州各地果园普遍受到危害,已成为当前苹果生产中亟待解决的问题。为此,从1979年开始,我们采用人工合成的桃小食心虫性诱剂(以下简称性诱剂)进行多点试验,取得了显著的防治效果。这种性诱剂是1977年日本农林技术研究所玉木佳男等人从桃小雌蛾虫中分离出的一种性息激素。它是由顺—7—二十烯—11酮(成分A)及顺—7—十九烯—11酮(成分B)两种成份按一定比例组成的。1978年中国科学院动物所也人工合成了这两种化学物质。1979年我所从该所得到了以橡胶塞为载体;配制比例为A:B=95:5及100:5,载 Peach Mung Beetle (hereinafter referred to as Peach) is the main fruit pest of fruit trees such as apple, pear and peach. In recent years, the orchards in various parts of our country have been generally endangered and have become the urgent problems to be solved in the current apple production. To this end, since 1979, we have used artificial synthetic peach moxibustion lure (hereinafter referred to as lure) for multi-point test, and achieved significant control effect. This sexual attractant was a sex hormone that was isolated from peach female moth in 1977 by Japan Agriculture and Forestry Technical Institute Tamaki Sugimoto et al. It is composed of cis-7-eicosen-11 ketone (component A) and cis-7-nonadecaene-11 ketone (component B) two components in a certain proportion. In 1978 the Institute of Animal Sciences of China also synthesized these two chemicals. In 1979 I obtained from the rubber plug as a carrier; the preparation ratio of A: B = 95: 5 and 100: 5, contained
