三种植物源农药对温室白粉虱生物活性的测定

Study of Bioactivity of Three Plant-origin Pesticides to Liriomyza Huidobrensis

狼毒根及茎叶、棘豆、黄花蒿对温室白粉虱的室内生物活性以狼毒根和茎叶较高,其1000倍液校正死亡率分别为81.27%和75.57%,棘豆、黄花蒿效果较差。

The bioactivity of pesticide derived from the stem and leaves of Stellera chamegasme L, Oxytropis latibiacteata Jurtz, Artemisia annua L. were studied to adult of Liriomyza huidobrensis. The results showed that root and stem of Stellera chamegasme L. showed higher bioactivity, the correct death ratio of diluted 1 000 times is 81.27%?75.57% respectively, the effect of Oxytropis latibiacteata Jurtz, Artemisia annua L. was not good.
