| Abstract: | Several phytoecdysteroids have been found in the extracts of A. multiflora and A.linearifolia using HPLC analysis. Those were 20-OH ecdysone, cyasterone, 3-acetate-20-OH ecdysone, 2-acetate-20-OH ecdysone, qugalactone. We found out that those phytoecdysteroids could lead the second instar larva of Clostera anastomosis and Stipnotia candida to death. The modified mortality rate was from 44.64% to 96.24%. Those extracts could signiticantly reduce the amount of nymph produced by the female Tuberolachnus 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 (1l7.57%). |
