近年来,北京地区种植蘑菇发展较快,但产量不稳定,特别是采收第3批蘑菇后,常因发生害虫将栽培块上的菌丝吃光,子实体长不出来,已长出的菇蕾很快萎缩,造成减产或失收。近两年,我们在北京市调查了20多个栽菇单位,在栽培的后期大多是都发生了蘑菇害虫,有些已造成了严重的损失。例如在1981年海淀区太舟坞人防,种的平菇发生了眼蕈蚊Lycoriella sp.虫口密度很大,将防空洞内新、老菌块的菌丝全部吃光,连培养料的棉子皮也被吃成丝状。据调查:虫害发生多的菇房往往是一、二种甚至是几种害虫同时发生,常见的害虫有:眼蕈蚊、蕈蚊、粪蚊、瘿蚊、蛾蚋、蚤蝇、跳虫、螨……。我们做过多种药剂试验,想找出
In recent years, Beijing mushroom growing faster, but the output is unstable, especially after the third batch of mushrooms, often due to the occurrence of pests on the cultivation of the mycelium eaten, fruiting bodies grow out, has grown Gulei quickly shrink, resulting in reduced production or loss. In the past two years, we surveyed more than 20 mushroom units in Beijing. Most of the mushroom cultivation occurred in the latter part of the cultivation period, and some of them have caused serious losses. For example, in 1981, Haidian District, TaiChungDu air defense, species of mushroom occurred in the eye of mosquitoes Lycoriella sp. Population density is very large, anti-empty hole in the new and old bacteria mycelium all eaten, Also eaten into filaments. According to the survey: the pest occurred more gullies are often one or two or even several pests occur at the same time, common pests include: eye mushroom, mushroom, malaria, mosquito, moths, flies, hoppers, Mites .... We have done a variety of pharmaceutical tests, to find out
