摘要
研究了白屈菜、大活的超声波水提物及其木醋液混合物对油松毛虫的防治效果。结果表明:白屈菜提取物加木醋液配制的杀虫剂稀释100倍,防治油松毛虫效果较好,死亡率为53.33%;大活提取物加木醋液配制的杀虫剂稀释5倍,防治油松毛虫效果最好,死亡率达到86.67%。
An experiment was conducted to study the control effects of the ultrasonic extracts from Chelidonium majus L, Angelica gigas Nakai. and their pyroligneous liquid on Dendrolimus tabulaeformis Tsai et Liu. Result showed that the ultrasonic extract from C. majus supplemented with the pyroligneous liquid （ 100 times dilution） was highly effective against D. tabulaeformis with a mortality rate of 53.33%, while the extract from A. gigas mixed with the pyroligneous liquid （5 times dilution） had the best control effect on D. tabulaeformis with a mortality rate of 86.67%.
