Responses of three Cyclocephala (Coleoptera: Scarabaeidae) species to hexane extracts of Cyclocephala lurida sex pheromone

Female pheromone extracts of the southern masked chafer, Cyclocephala lurida Bland, or the northern masked chafer, Cyclocephala borealis Arrow, previously were shown to attract males of both species. A hexane extract of C. lurida was used in traps at a garden center to test its possible attractiveness to C. pasadenae and C. longula, two other sympatric species. Neither of the other species was attracted to the lurida pheromone.
