Beet armyworm, Spodoptera exigua, diamondback moth, Plutella xylostella and tobacco cutworm, Spodoptera litura are the three most serious pests of many economically important crops such as cruciferous crops, various vegetables and ornamental plants. Because these pests are known to be resistant to lots of chemical insecticides, integrated control using both or either entomophathogen and/or natural enemy is thought to be an attractive alternative for effective control. One of the obstacles using and expanding mycopesticide is narrow host ranges. At commercial farms, cultivating crops are seriously damaged by various Lepidopteran pests. Farmers want to use a microbial control agent which can control various host insects to reduce cost and labor. In previous study, we selected two entomopathogenic fungi, Metarhizium anisopliae and Paecilomyces fumosoroseus, which shown high virulence against beet armyworm. For wide use of the isolates in farm, we tested its host ranges, especially to diamondback moth and tobacco cutworm, which also are serious pest in Korea. The two isolates were shown a good control effect in leaf disc bioassy.
