英文摘要 | Toxicity of nine insecticides used to control silverleaf whitefly, Bemisia argentifolii Bellows & Perring were evaluated against adults of Eretmocerus orientalis Silvestri. The dosages of selected insecticide testing dosages studied were equivalent to those recommended in the field and their 1/2, 1/4 dosages respectively. Adults were released into glass tube with fresh dried insecticide film under ventilation for 24,48,72 hours and mortalities were recorded. Results revealed that deltamethrin, bifenthrin, cartap and chlorpyrifos were harmful (mortality >99%) to adults of E. orientalis under tested concentrations 24 hours after exposure. Imidacloprid, pymetrozine and abamectin were moderately harmful (mortality=80-99%) where as the hexaflumuron and buprofezin proved to be harmless (mortality <50%). |
