Abstract: The attraction of the cotton bollworm, Helicoverpa armigera (Hübner), to poplar bundles made from branches of the Chinese wing-nut tree, Pterocarya stenoptera, and the sex pheromone bait was assayed in the field. The results showed that these bundles were attractive to H. armigera. The amount of male and female moths trapped by the bundles was positively correlated, with most moths captured being females. Sex pheromone bait did not increase the number of moths trapped by the bundles. The mechanism of attraction of these bundles for H. armigera is discussed.

Key words: Pterocarya stenoptera, Helicoverpa armigera, sex pheromone, attraction
