茶园害虫致病微生物茶园害虫致病微生物pathogenic microbes of pests in tea plantation 茶圈，虫致脚徽生物比5 of(pathogeniein tea Plantation)nllCro- 侵染业科学院茶叶研究所等单位还发现有:圆抱虫霉寄生小绿叶蝉，虫草菌寄生扁刺蛾、茶刺蛾，球赤壳菌寄生茶牡蜘蚊，稼祥寄生茶毛虫、云尺续等，红霉菌寄生娜圆幼，拟青祥寄生肾纹毒蛾、茶细蛾、褐刺蛾等。 不少病原真菌都可进行人工生产，国内则以白僵菌生产较多。在生产中重要的是选取优良的菌种和培养基，控制培养条件和防止污染。其土法生产的工艺流程:从自然似虫分离选取优良菌种一、试管斜面培养一、转入瓶、堆进行二级培养一*转入大床进行三级固体扩大培养一一，出料在40一45℃条件下干燥一、粉碎过筛100筛目一一侧定活抱子含量一、包装密封一一阴凉干燥处贮存备用。白僵菌除菌种培养外，一般对营养条件要求不高，菌种培养基可用马铃薯20%，蔗籍2%，琼脂2%加水配制;二级培养则可用淘米水(5oo克水淘500克米);三级扩大培养可用米糠40%麦轶30%，谷壳30%，加水适量(不超料重)。为了进一步提高产量和产品质量，宜进行液体深层发醉的工业生产。 细菌病大多由芽抱杆菌科(B acillaceae)芽抱杆菌属才肠ct’llus)的细菌感染所致。苏芸金杆菌(B.th“万伙卯召嘴司已经工厂化生产，广泛用于防治蛾蝶类及其它农业害虫。苏芸金杆菌的营养体呈直形较粗杆状，两端钝圆，有厚膜，长宽为1.2一1.8X3.0一5.0徽米。周生鞭毛微动或不动。营养体单个存在或几个结成链状，在适宜条件下经过不断裂殖，老熟形成长卵口形抱子炭，抱子囊最后破裂放出一个芽泡和一个伴抱晶体。芽抱卵圆形，有光泽，长宽为0.8一0.9x2.0徽米，在适宜条件下再萌发裂殖。伴抱晶体多呈菱形或近方形，长宽为o.6x2.0微米，含有毒素，在碱性溶液中释放出来，对害虫具有很强的毒力。害虫吞食经消化道侵入体腔。峨搽类幼虫肠液呈碱性，正利于毒素析出毒杀害虫。病死虫体变软，变形，色暗，组织解体脓化，并有奥味，故亦称脓病或软化病。苏芸金杆菌有很多变种，如青虫菌、松毛虫杆菌、杀螟杆菌、“7216”、“HD一l”等。在茶树害虫中也常有自然感染和人工应用。例如福建茶科所用0.2亿饱子/毫升菌液防治茶毛虫，5天后死亡75一90%。安徽祁门茶科所用同样剂量防治茶蚕，5天后死亡100%:0.5亿/毫升菌液防治茶蓑蛾.10天后死亡78一100%。
