Flight behavior of parasitoids Microsplitis croceipes Cresson (Braconidae) and Campoletis sonorensis (Cameron) (Ichneumonidae) was examined in a wind tunnel. Both species exhibited odor directed, oriented flights to cotton, although flight frequency was related to variation in wind velocity or differential cotton volatile emission with changes in wind velocity, or both. Flight frequency at constant wind velocity was affected by illumination. Microplitis croceipes was attracted to the wind borne odor of Heliothis virescens (F.) frass and larvae, whereas C. sonorensis was not. Possible interaction of the wind borne odors from the habitat and host is suggested for parasitoids.
