Anti-oviposition and repellence of Cordyceps fumosorosea against Spodoptera exigua
Anti-oviposition induced by Cordyceps fumosorosea FG340 to Spodoptera exigua and its persistence had been assessed on the Chinese cabbage seedlings sprayed with 0, 10 6 , 10 7 and 10 8 conidia per mL in greenhouse and laboratory. In a randomized complete block, four couples (males and females) of mo...
