虫草的被毛孢无性型新种及其对黄粉虫的侵染研究
虫草的被毛孢无性型新种及其对黄粉虫的侵染研究李春如 夏成润 林英任 樊美珍 李增智 摘要：报道采自安徽省黄山风景区的虫草Cordycepsformosana,多批次收集弹射的子囊孢子分离得到其无性型,经鉴定为一被毛孢新种,命名为黄山被毛孢Hirsutella huangshanensis.黄山被毛孢在米饭培养和自制的虫草培养基上均能长出子实体,其菌落及子实体颜色与天然虫草较为相似,但未见成熟的子囊壳.应用黄山被毛孢RCEF0868菌株对饲喂昆虫黄粉虫进行感染试验,结果表明:黄粉虫在菌落接触感染、刚蜕皮幼虫的穿刺接种和孢子浓度1.0×107/ml浸蘸处理下,获得了相对较高的侵染率,分别达到30%、25%和25%,刚蜕皮幼虫一般比深色幼虫组其侵染率较高,1×105/ml孢子浓度浸蘸试虫不论是刚蜕皮或老熟幼虫均不能感染.10d后被感染的黄粉虫形成僵虫,继续保湿培养20d后,体表节间膜处形成白色菌膜,粘片镜检表明感染真菌即为供试菌株.40d后,可见子实体原基及孢梗束,尚未见成熟的子囊壳. 关键词：黄山被毛孢;虫生真菌;侵染率分类号：Q939.5文献标识码：A 文章编号：1672-6472(2005)03-0349-0355 HIRSUTELLA HUANGSHANENSIS SP.NOV., THE ANAMORPH OF CORDYCEPS FORMOSANA AND ITS INFECTION ON TENEBRIO MOLITOR LI Chun-Ru XIA Cheng-Run LIN Ying-Ren FAN Mei-Zhen LI Zeng-Zhi 基金项目：安徽省自然科学基金资助作者简介：樊美珍,Corresponding author:mzfan@ahau.edu.cn 作者单位：李春如（安徽农业大学微生物防治省重点实验室,合肥,230036;安徽医科大学基础医学院,合肥,230032）夏成润（安徽农业大学微生物防治省重点实验室,合肥,230036）林英任（安徽农业大学微生物防治省重点实验室,合肥,230036）樊美珍（安徽农业大学微生物防治省重点实验室,合肥,230036）李增智（安徽农业大学微生物防治省重点实验室,合肥,230036） 参考文献： [1]Hywel-Jones NL, 1997.
