摘要：
Several phytoecdysteroids have been found in the extracts ofA. multiflora andAlinerifolia using HPLC analysis. Those were 20-OH ecdysone, cyasterone. 3-acetate-20-OH ecdysone. 2-acetate-20-OH edysone, ajugalactone. We found out that those phytoecdy steroids could lead the second instar larva ofClostera anastomosis andStilpnotia candida to death. The modified mortality rate was from 44.64% to 96.24%. Those extracts could significantly reduce the amount of nymph produced by the femaleTuberolachnus salignus. The number of the nymph produced after treating with those extracts was only 20% to 70% of that produced by the untreated group. The death rate of the newly produced nymph which treated was among 33.33% to 58.82%. It was much higher than the death rate of the control group (17.57%).
