Activity of adult bollworms, Heliothis zea (Boddie) and tobacco budworms, H. virescens (F.), was monitored with BL and pheromone traps. Light traps captured far more of both sexes of bollworms than of tobacco budworms; pheromone traps seemed more effective in early season when populations were low. When both species were combined as attractants in...

... Some field trapping studies have suggested that one species can recognize sex pheromone component of other sympatric species. A specific pheromone component of H. virescens, Z9-14:Ald, played an intraspecific role in sexual communication, and also served as behavioral antagonist for H. zea to avoid the cross-attraction (Haile et al., 1973;Roach, 1975;Carpenter et al., 1984;Hansson et al., 1986;Grant et al., 1987;Christensen et al., 1990). As a minor component of the sex pheromone in Chilo suppressalis, Z11-16:OH did not increase the attractiveness of the pheromone for conspecific males in the field, but did increase the sex pheromone specificity (Chen et al., 2018). ...
