摘要: 马尾松毛虫Dendrolimus punctatus Walker性信息素的主要活性组分为顺5,反7-十二碳二烯醇、顺5,反7-十二碳二烯基乙酸酯、顺5,反7-十二碳二烯基丙酸酯,在橡胶塞诱芯载体上很快发生异构化。半月后以顺反式为主的三组分已改变为以反反式为主体,反顺式和顺顺式也增加了。因而,此类材料不宜作为共轭二烯类信息素的载体。本文报告了一种硅橡胶材料对共轭双键具有相当小的影响,并可望成为含有共轭双键结构的昆虫信息素的载体材料。

Abstract: Z5, E7-Dodecadien-ol, its acetate and propionate, the major sexpheromone components of the pine caterpillar moth, Dendrolimus punctatus Walker,were isomerized facilely on natural rubber dispensers. The high percentage of the Z,E-isomers in the original synthetic samples decreased quickly. After 15 days the E,E-isomers became dominant. The contents of E, Z-and Z, Z-isomers also increased to certain extent. It seemed that the natural rubber was not a good matrix as a dispenser for sex pheromone with conjugated double bonds. It was also demonstrated that a kind of silicone rubber had minimum effect on isomerization.
