菌虱是对蘑菇生产危害较大的一种害虫,多发生在播种以后。目前危害蘑菇的菌虱主要有两种:蒲螨和粉螨。蒲螨体小,肉跟不易看到,多在料面或土粒上集中成团,体色呈咖啡色,似六六六粉;粉螨体较大,白色发亮不成团,发生多时呈粉状。蒲螨和粉螨繁殖均很快,都以蘑菇菌丝为食,常群集于菌种周围,咬食幼嫩菌丝,菌丝被害后不能萌发。蒲螨比粉螨对蘑菇的危害为大,发生严重时不出蘑菇。 蒲螨与粉螨主要来源于仓库、饲料间,或鸡棚里的粗糠、棉籽饼、菜籽饼等饲料中。因此菌种培养室、蘑菇房要远离仓库、饲料间、鸡棚等。要经常检查菌种,如发现瓶口菌丝有萎缩退化现象,可用放大镜观察瓶口周围是否有螨类。如有螨类,应 Bipola is a pest that harms the production of mushrooms, mostly after sowing. At present, there are mainly two kinds of mushroom lice that are harmful to mushrooms: Po mite and powder mite. Po mite body, meat and not easy to see, and more in the material or soil particles concentrated into groups, body color was brown, like six six six powder; powder mite body, white shiny group, occurred when the powder shape. Po mites and powder mites breeding are fast, all mushrooms mycelium for food, often clustered around the species, biting young mycelium, mycelium can not germinate after being killed. Po mites than the powder mite harm to mushrooms, in the event of serious mushrooms. Po mites and powder mites are mainly derived from the warehouse, feed room, or chicken shed where the bran, cottonseed cake, rapeseed cake and other feed. Therefore, bacteria culture room, mushroom room away from the warehouse, feed room, chicken shed and so on. To regularly check the strain, such as bottleneck found atrophy shrinkage phenomenon, the magnifying glass can be used to observe the bottle around the mites. If mites, should
