萊氏綠殭菌(學名:Metarhizium rileyi),又名莱氏野村菌、萊氏野村黴,有時簡稱綠殭菌,是黑殭菌屬的一種蟲生真菌,可感染玉米穗蟲、番茄夜蛾、甜菜斜紋夜蛾、草地貪夜蛾(秋行軍蟲)等超過60種鱗翅目昆蟲的幼蟲,而有用作生物農藥以抑制數種農業害蟲生長的潛力[6]。本種過去屬於野村黴屬(Nomuraea),2014年,一篇分子種系發生學研究結果顯示野村黴屬為複系群,並將本種該歸入黑殭菌屬[7][8]。
感染過程
[编辑]萊氏綠殭菌感染昆蟲的過程可分為數個階段,其分生孢子為疏水性,可結合於同為疏水性的昆蟲體表,孢子表面的多種水解酵素可分解昆蟲的表皮,並於環境適宜時萌發成菌絲,穿透昆蟲表皮而進入其體內。當菌絲長至昆蟲的血淋巴時,會形成許多芽孢體(hyphal bodies, hb),芽孢體可脫離菌絲,如酵母菌般在血淋巴中自由複製、生長,其細胞表面的病原相關分子模式不被昆蟲的吞噬細胞視為外來者,因此不會受到攻擊。當芽孢體的密度達到一閾值時,會透過群體感應使其會轉換回菌絲頂端生長(apical growth)的生長模式[9],形成菌絲體,同時可分泌多種酵素,在數小時內快速殺死宿主並分解其組織[10][11]。
生物農藥
[编辑]萊氏綠殭菌可作為生物農藥,用以控制多種鱗翅目的農業害蟲。以萊氏綠殭菌控制草地貪夜蛾(秋行軍蟲)蟲害的生物農藥正在研製開發中[12]。
