几种低毒农药对韭菜迟眼蕈蚊幼虫的毒力测定
Toxicity Determination of Several Low Toxicity Insecticides to Larval of Bradysia odoriphaga
摘要
Abstract
To relieve the problems of insecticide resistance of Bradysia odoriphaga and excessive insecti-cide residues of Chinese chive because of high toxicity insecticides used for a long time,the toxicities of 6 kinds of low toxicity insecticides to 3 -instar larvae of Bradysia odoriphaga were evaluated in laboratory.The results showed that after treated for 96 hours,the order of insecticidal toxicity was as follows:phoxim >chlor-pyrifos >doramectin >tefluthrin >chlorfluazuron >hexaflumuron >milbemycin >Tianwei -streptozotocin.The killing speed of phoxim and chlorpyrifos were more quick than the other 6 insecticides.When the concentra-tion was 20 mg/L,the LT50 of phoxim and chlorpyrifos was 24.185 h and 39.092 h respectively.When the concentration was 100 mg/L,the LT50 of the other 6 insecticides was as follows:tefluthrin >doramectin >chlorfluazuron >hexaflumuron >milbemycin >Tianwei -streptozotocin.关键词
