臺灣蟲草的被毛孢無性型新種及其對黃粉蟲的侵染研究 李春如 夏成潤 林英任 樊美珍 李增智 摘 要：報道采自安徽省黃山風(fēng)景區(qū)的臺灣蟲草Cordycepsformosana,多批次收集彈射的子囊孢子分離得到其無性型,經(jīng)鑒定為一被毛孢新種,命名為黃山被毛孢Hirsutella huangshanensis.黃山被毛孢在米飯培養(yǎng)和自制的蟲草培養(yǎng)基上均能長出子實體,其菌落及子實體顏色與天然蟲草較為相似,但未見成熟的子囊殼.應(yīng)用黃山被毛孢RCEF0868菌株對飼喂昆蟲黃粉蟲進行感染試驗,結(jié)果表明:黃粉蟲在菌落接觸感染、剛蛻皮幼蟲的穿刺接種和孢子濃度1.0×107/ml浸蘸處理下,獲得了相對較高的侵染率,分別達到30%、25%和25%,剛蛻皮幼蟲一般比深色幼蟲組其侵染率較高,1×105/ml孢子濃度浸蘸試蟲不論是剛蛻皮或老熟幼蟲均不能感染.10d后被感染的黃粉蟲形成僵蟲,繼續(xù)保濕培養(yǎng)20d后,體表節(jié)間膜處形成白色菌膜,粘片鏡檢表明感染真菌即為供試菌株.40d后,可見子實體原基及孢梗束,尚未見成熟的子囊殼. 關(guān)鍵詞：黃山被毛孢;蟲生真菌;侵染率 分類號：Q939.5 文獻標識碼：A 文章編號：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 基金項目：安徽省自然科學(xué)基金資助 作者簡介：樊美珍,Corresponding author:mzfan@ahau.edu.cn 作者單位：李春如（安徽農(nóng)業(yè)大學(xué)微生物防治省重點實驗室,合肥,230036;安徽醫(yī)科大學(xué)基礎(chǔ)醫(yī)學(xué)院,合肥,230032） 夏成潤（安徽農(nóng)業(yè)大學(xué)微生物防治省重點實驗室,合肥,230036） 林英任（安徽農(nóng)業(yè)大學(xué)微生物防治省重點實驗室,合肥,230036） 樊美珍（安徽農(nóng)業(yè)大學(xué)微生物防治省重點實驗室,合肥,230036） 李增智（安徽農(nóng)業(yè)大學(xué)微生物防治省重點實驗室,合肥,230036） 參考文獻： [1]Hywel-Jones NL, 1997.
