马尾松毛虫(Dendrolimus puncta-tus walker)、油松毛虫(Dendrolimustabulaeformis Tsai et Liu)、落叶松毛虫(Dendrolimus Laticis Tschelweri-kov)、赤松毛虫(Dendrolimus specta-bilis Butler)这四种松毛虫,是我国从南到北松树上的主要害虫,目前,马尾松毛虫性外激素的结构已由我国鉴定出来,其成分为顺,反-5.7-十二碳二烯醇及其乙酸酯和丙酸酯,这三种成分的不同比例混合后,以3:5:2的500微克量在林间具有较强的诱蛾活性。为了寻找马尾松毛虫性外激素的其它增效化合物,并对另外三种松毛虫性
Dendrolimus puncta-tus walker, Dendrolimustabulaeformis Tsai et Liu, Dendrolimus Laticis Tschelweri-kov and Dendrolimus specta-bilis Butler, At present, the structure of the sex pheromone of Dendrolimus punctatus has been identified in our country. Its composition is cis, trans-5.7-dodecadienol and its acetate and propionate, The three components in different proportions mixed with 3: 5: 2 amount of 500 micrograms in the forest has a strong attraction of moth activity. In order to find other synergistic compounds of the Dendrolimus punctatus sex pheromone,
