The parasitoid wasp Telenomus remus is a useful biological control agent for fall armyworm (Spodoptera frugiperda), a significant pest of a variety of crops. It naturally parasitizes fall armyworm eggs, but research has shown that, when rearing T. remus en masse, using eggs of the rice moth (Corycyra cephalonica) is significantly more cost effective.
