莱氏绿僵菌
莱氏绿僵菌(学名:Metarhizium rileyi),又名莱氏野村菌、莱氏野村霉,有时简称绿僵菌,是黑僵菌属的一种虫生真菌,可感染玉米穗虫、番茄夜蛾、甜菜斜纹夜蛾、草地贪夜蛾(秋行军虫)等超过60种鳞翅目昆虫的幼虫,而有用作生物农药以抑制数种农业害虫生长的潜力[6]。本种过去属于野村霉属(Nomuraea),2014年,一篇分子种系发生学研究结果显示野村霉属为复系群,并将本种该归入黑僵菌属[7][8]。

感染过程
编辑莱氏绿僵菌感染昆虫的过程可分为数个阶段,其分生孢子为疏水性,可结合于同为疏水性的昆虫体表,孢子表面的多种水解酵素可分解昆虫的表皮,并于环境适宜时萌发成菌丝,穿透昆虫表皮而进入其体内。当菌丝长至昆虫的血淋巴时,会形成许多芽孢体(hyphal bodies, hb),芽孢体可脱离菌丝,如酵母菌般在血淋巴中自由复制、生长,其细胞表面的病原相关分子模式不被昆虫的吞噬细胞视为外来者,因此不会受到攻击。当芽孢体的密度达到一阈值时,会透过群体感应使其会转换回菌丝顶端生长(apical growth)的生长模式[9],形成菌丝体,同时可分泌多种酵素,在数小时内快速杀死宿主并分解其组织[10][11]。
生物农药
编辑莱氏绿僵菌可作为生物农药,用以控制多种鳞翅目的农业害虫。以莱氏绿僵菌控制草地贪夜蛾(秋行军虫)虫害的生物农药正在研制开发中[12]。
