Anti-oviposition induced by Cordyceps fumosorosea FG340 to Spodoptera exigua and its persistence had been assessed on the Chinese cabbage seedlings sprayed with 0, 10⁶, 10⁷ and 10⁸ conidia per mL in greenhouse and laboratory. In a randomized complete block, four couples (males and females) of moths were released in each cage. In the laboratory, the percentage of egg laid varied significantly between treatments with 59.8, 14.8, 11.9, and 13.5% on 0, 10⁶, 10⁷ and 10⁸ conidia per mL; respectively. Similarly, in the greenhouse, the percentage of eggs laid differed significantly between suspensions with 88.18, 8.7, 0, and 3.13% on 0, 10⁶, 10⁷, and 10⁸ conidia per mL; respectively. Repellence study showed that there is a major difference between suspensions with average 34.55, 35.21 and 40.02% for 10⁶, 10⁷ and 10⁸ conidia per mL; respectively. Endophytic C. fumosorosea and its culture fluid affect the behavior of armyworm larvae. The concentration of 10⁸ conidia per mL can affect the oviposition of the armyworm.

烟色冬虫夏草FG340 对甜菜夜蛾的抗产卵作用及其持久性在温室和实验室中用每毫升0、10 ⁶、10 ⁷和 10 ^{8 个分生孢子喷洒的大白菜幼苗进行了评估。}在一个随机的完整区组中，每个笼子中释放了四对（雄性和雌性）飞蛾。在实验室中，产卵百分比在每毫升 0、10 6 、10 7 和 10 8 个分生孢子^上分别^为59.8、14.8、11.9^{和13.5% 的处理之间存在显着差异；}分别。类似地，在温室中，悬浮液之间的产卵百分比显着不同，分别为 88.18%、8.7%、0 和 3.13%，分别为 0、10每毫升⁶、 10 ⁷和 10 ^{8个分生孢子；}分别。驱避性研究表明，悬浮液之间存在显着差异，平均每毫升10 ⁶、10 ⁷和 10 ^{8 个分生孢子分别为 34.55%、35.21% 和 40.02%；}分别。内生C. fumosorosea及其培养液影响粘虫幼虫的行为。^{每毫升10 8 个}分生孢子的浓度可以影响粘虫的产卵。
