Pheromone cross-attraction and inhibition among four coneworms, Dioryctria spp. (Lepidoptera: Pyralidae) in a loblolly pine seed orchard
Environmental Entomology 13 (5), 1298-1301
Abstract: Pheromone cross-attraction and inhibition among four species of coneworms was tested by using different combinations of synthetic pheromone baits for Dioryctria disclusa Heinrich (30 µg of [Z]-9-tetradecenyl acetate [Z9-14: Ac]), D. clarioralis (Walker) (30 µg of 88:12% Z9-14: AC to [E]-9-tetradecenyl acetate), and D. amatella (Hulst) (300 µg of [Z]-11-hexadecenyl acetate) in pheromone traps. Captures of D. disclusa and D. merkeli Mutuura and Monroe males were significantly reduced by the presence of D. amatella attractant. D. disclusa males were also inhibited by D. clarioralis attractants. D. merkeli males were attracted equally by the pheromones of D. disclusa and D. clarioralis. Catches of D. amatella and D. disclusa were highest in those traps baited with their respective attractants alone. D. clarioralis males were attracted more to D. disclusa pheromone baits than to their own. The pheromone of D. amatella did not significantly reduce trap catches of D. clarioralis. The strong cross-attraction among D. disclusa, D. merkeli, and D. clarioralis will allow seed orchard managers to monitor one set of traps for all three species. However, the inhibition of D. amatella by D. disclusa and D. clarioralis baits will require a separate set of traps for this species.
