Anti-oviposition and repellence of Cordyceps fumosorosea against Spodoptera exigua

Abstract 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 , 7 8 conidia per mL in greenhouse laboratory. In a randomized complete block, four couples (males females) of moths were released each cage. laboratory, percentage egg laid varied significantly between treatments 59.8, 14.8, 11.9, 13.5% mL; respectively. Similarly, greenhouse, eggs differed suspensions 88.18, 8.7, 3.13% Repellence study showed that there is major difference average 34.55, 35.21 40.02% for Endophytic C. culture fluid affect behavior armyworm larvae. The concentration can oviposition armyworm.
