| Abstract: | Extracts of an annual medicinal plant,Artemisia annua L.(Asteraceae),were bioassayed to determine their acaricidal activities against Tetranychus cinnabarinus(Boisduval) in laboratory.The acetone extract of the plant showed the most potent acaricidal activity against T.cinnabarinus(LC_(50)=0.206 6 g/L).The corrected mortality of acetone extract from A.annua at 10 g/L against T.cinnabarinus was 90.64% and 100%,respectively,after 48 and 72 h the contact treatment. |
