- 摘要:
- 以平菇为试材，选择4种杀虫剂，分别在实验室和菇房条件下研究其对异迟眼蕈蚊的防治效果，并在实验室内考察其对秀珍菇菌丝生长的影响。结果表明：0.3%印楝素乳油对异迟眼蕈蚊2龄幼虫毒力最高，LC50为13.486 mg/L，但对秀珍菇菌丝生长抑制较大，EC50小于9.845 mg/L；供试药剂对异迟眼蕈蚊成虫均有防治效果，但3 000 IU/mg苏云金杆菌以色列亚种各浓度处理对秀珍菇菌丝生长抑制较大。除虫脲和灭蝇胺对秀珍菇菌丝生长抑制较小，其余均表现较高的安全性。
- Abstract:
- Taking mushroom as material，control efficiency of four insecticides on Bradysia difformis was studied under the condition of laboratory and house of the edible fungi.The side-effects of tested insecticides on mycelium growth of Pleurotus geesteranus were tested.The results showed that the greatest insecticidal activity against 2 larvea of B.difformis were azadirachtin，LC50 value was 13.486 mg/L.But the greatest inhibitory effects of pesticides on the growth of Pleurotus geesteranus mycelium was azadirachtin whose EC50 value was less than 9.845 mg/L.Insecticides to B.difformis adults had effects，but mushroom mycelia growth of Pleurotus geesteranus was restrained significantly by 3 000 IU/mg Bti.Inhibitory effects of cyromazine and diflubenzuron on the growth mycelium of Pleurotus geesteranus were weak and better security for all.
