| 摘 要： | 应用8种杀虫剂对槐花球蚧若虫进行室内毒力测定,结果表明:供试杀虫剂对槐花球蚧若虫的毒力(LC50值)大小依次为2.2%阿维菌素苯甲酸盐微乳剂(0.370 2 mg/L)>噻虫啉乳油(0.726 4 mg/L)>40%毒死蜱乳油(1.564 6 mg/L)>0.5%藜芦碱可溶性粒剂(3.409 7 mg/L)>5%桉油精可溶性粒剂(4.415 1 mg/L)>40%丙溴磷乳油(6.782 4 mg/L)>40%杀扑磷乳油(17.239 4 mg/L)>2.5%高效氯氟氰菊酯可溶性粒剂(22.300 3 mg/L)。

| Abstract: | The toxicity experiment of 8 kinds of insecticides to the larva of Eulecanium kuwanai Kanda was carried out.Results showed that:The order of toxicities of the 8 insceticides from high to low against the larva of Eulecanium kuwanai Kanda was 2.2% emamectin benzoate ME(0.370 2 mg/L) >thiacloprid EC(0.726 4 mg/L)>40% chlorpyrifos avermectin EC(1.564 6 mg/L)>0.5% sabadigga SG(3.409 7 mg/L)>5% cineoge SG(4.415 1 mg/L)> 40% profenofos EC(6.782 4 mg/L)>40% methidathion EC(17.239 4 mg/L)> 2.5% lambda-cyhalothrin SG(22.300 3 mg/L). |
