This research project investigates the distribution and prevalence of trichomycete fungi present in blackfly larvae and adults in the region of Cambridge, New York. In blackfly larvae, two genera of Harpellaceae, Stachylina and Harpella, were observed in midguts, and four genera of Legeriomycetaceae-Pennella, Genistellospora, Simuliomyces, and Smittium-in hindguts, with a total of seven species recorded. This is the first published report of Stachylina spp. in blackflies. Field data indicated that sampling date, host species, and location were all important variables affecting trichomycete prevalence in larvae. We report the successful laboratory infection of blackfly larvae with in vitro cultured Smittium simulii, and production of H. melusinae and G. homothallica trichospores from cysts dissected from the ovaries of infected flies.
本研究项目调查了纽约剑桥地区蚋幼虫和成虫中毛菌纲真菌的分布及流行情况。在蚋幼虫中，在中肠观察到了哈珀菌科的两个属，即柱形菌属和哈珀菌属，在后肠观察到了类腿菌科的四个属——彭内拉菌属、类吉斯特孢菌属、蚋生菌属和斯米蒂菌属，共记录到7个物种。这是关于柱形菌属在蚋中的首次发表报告。野外数据表明，采样日期、宿主物种和地点都是影响幼虫中毛菌纲真菌流行率的重要变量。我们报告了用体外培养的斯米蒂蚋菌成功感染蚋幼虫，并从感染苍蝇卵巢中解剖出的囊肿中产生了梅氏哈珀菌和同宗配合吉斯特孢菌的毛孢子。
