用山苍子芳香油拌种防治蚕豆象成虫Bruchus rufimanus Boheman每50公斤蚕豆拌油300克两,12天后成虫死亡率达95.8％。在22—28℃下,用200ml/m~3的山苍子油薰蒸8天,成虫死亡率达100％,其LC_(50)为59.6ml/m~3,LC_(95)为134.9ml/m~3。3月份在20℃下,山苍子油薰蒸成虫的LT_(50)为177.8小时,LT_(95)为707.9小时;在25℃下薰蒸,LT_(50)为86.6小时,LT_(95)为334.9小时;在30℃下薰蒸,LT_(50)为50.1小时,LT_(95)为141.2小时;在36℃下薰蒸,不到24小时成虫即全死。山苍子油毒杀幼虫的效果较差。此油平时可供人们药用和食用,也不影响蚕豆发芽。
