摘要:
Adult male bollworm,Heliothis zea(Boddie), moths were collected from sex pheromone traps located in Arkansas and were examined for pollen. Pollen was found on 68.3% of the moths, primarily on the proboscis or eye area. Pollen of false mesquite,Calliandra, and ape's earring,Pithecellobium, were found on moths during each of 2 yr. Neither plant occurs in Arkansas;Calliandra'sclosest distribution to Arkansas is south central Texas, andPithecellobiumoccurs in south Texas near the Mexican border. The presence of these pollens onH. zeaindicates immigration from at least 750 km to the Arkansas capture sites.
