[目的]筛选出对平菇厉眼蕈蚊幼虫具有较好毒杀作用的生物农药,为平菇厉眼蕈蚊的生物防治提供依据。[方法]采用拌料法分别测定药剂对平菇厉眼蕈蚊幼虫的毒杀作用,采用平板加药法测定药剂对平菇菌丝生长的影响。[结果]除虫菊素、苦参碱对平菇厉眼蕈蚊幼虫具有较高毒力,其LC50值分别为10.4178、20.0953 mg/L;印楝素对平菇菌丝抑制最强,其EC50值为0.4854 mg/L。[结论]除虫菊素、苦参碱可作为防治平菇厉眼蕈蚊的生物药剂。
[Objective] The research aimed to select bio-pesticides which have good toxic and killing effects on Pleurotus eryngii larvae and provide basis for the biological control of Pleurotus eryngii. [Method] The poisoning effect of medicament on the larvae of Mushrooms was evaluated by the method of mixing materials. The effects of the agents on the growth of Pleurotus ostreatus were determined by plating plate method. [Result] Pyrethrins and matrine had higher virulence to Pleurotus eryngii larvae with LC50 values of 10.4178 and 20.0953 mg / L, respectively. Azadirachtin had the strongest inhibitory effect on Pleurotus ostreatus, and its EC50 value 0.4854 mg / L. [Conclusion] Pyrethrins and matrine could be used as biological agents to prevent and cure Pleurotus eryngii.
