小彎孢殼菌超寄生在香蕉黃葉病原真菌的首例報告

First record of Eutypella sp. as a mycoparasite on Fusarium oxysporum f. sp. cubense

從臺灣香蕉的假莖分離鑑定一株新的小彎孢殼菌，在共培養的情況下，小彎孢殼菌的菌絲會穿透或纏繞香蕉黃葉病原真菌的菌絲，造成孔洞或傷痕。本報告為蕉孢殼菌科寄生菌的首例報告，具有生物防治開發的潛力。

"Fusarium wilt of banana (Musa sapientum) caused by Fusarium oxysporum f. sp. cubense (FOC) is one of the most economically devastating plant diseases in the world (Hwang and Ko 2004). This disease is difficult to control with pesticides, therefore many bio-control strategies have been researched and developed (Cao et al. 2005; Nel et al. 2006; Sivamani and Gnanamanickam 1988). Whilst screening for potential antimicrobials from banana, we found a mycoparasite in dual culture with FOC."
