Microbe have been considered as potential control agents for pest, as alternative to chemical control methods. Among entomopathogens, fungi cause the mortality by penetrating the cuticle of pest and/or by metabolites such as toxin. Not only this direct control effect of fungi, but repellency of fungi also may be used to prevent the pest. Repellence effect of fungi is considered as inhibitory factor to control termite. A study was reported in Japan that termite was able to detect and remove the conidia of fungi on their surface. The termite can escape from fungal infection and protect their colony. There is few study that insect pest such as moth can detect and avoid the virulence fungi. Therefore, we has been conducting the detection and avoidance of beet armyworm to high pathogenic fungi, Paecilomyces fumosoroseus. Adult of the beet armyworm avoided oviposition at Chinese cabbage treated with P. fumosoroseus compare to control. This result may be used to prevent the infestation of moth in crop production.
