摘要
以韭菜迟眼蕈蚊成虫和幼虫为试材,采用胃毒触杀联合毒力法和成虫药膜法,测定几种杀虫剂对韭菜迟眼蕈蚊成虫和幼虫的毒力。结果表明:二嗪磷对韭菜迟眼蕈蚊幼虫具有较高的活性,为59.05mg/kg,其次为阿维菌素,为72.89mg/kg;对成虫测定结果表明,联苯菊酯、马拉硫磷对成虫活性高于噻虫嗪、烯啶虫胺,分别为0.30、0.15mg/kg,对成虫表现出良好的活性。二嗪磷、阿维菌素、联苯菊酯、马拉硫磷可以作为韭菜迟眼蕈蚊幼虫、成虫期防治的理想药剂。
Adult and larva of Bradysia odoriphagawere used as test materials using the stomach and contact poison test,glass-vials method,effect of different insecticides on adult and larva of Bradysia odoriphagawere measured.The results showed that among all the tested chemicals,diazinon had the highest toxicity to the insect,and the LC50 value was59.05mg/kg.That of abamectin was 72.89mg/kg.The glass-vials test to adults showed that the biological activity of bifenthrin and malathion to the insect were higher than nitenpyram and thiamethoxam,with the LC50 values were0.30mg/kg,0.15mg/kg,respectively.Diazinon,abamectin and bifenthrin,malathion could be used as ideal insecticides to control the larva and adult of Bradysia odoriphaga.
