摘要
应用喷雾法测定10种低毒杀虫剂对松突圆蚧(Hemiberlesia pitysophila)2龄若虫的敏感性。实验结果表明,阿维菌素对松突圆蚧地杀虫活性最高,其LC50为8.56 mg/L,其次为杀虫单,LC50为23.23 mg/L,阿克泰,LC50为58.22 mg/L,活性最差的是茶皂素,LC50为33 995 mg/L。
The sensibility of second instars nymphs of Hemiberlesia pitysophila in 10 low-toxic insecticides was detected by using spray method.The result showed that Avermecti had the best insecticidal acitivity against Hemiberlesia pitysophila（8.56 mg/L for LC50）,followed by Monosultap（23.23 mg/L for LC50）and Actara（58.22 mg/L for LC50）.Tea Saponin had the lowest insecticidal activity against Hemiberlesia pitysophila（33 995 mg/L for LC50）.
