Carpophilus spp. (Coleoptera: Nitidulidae) responses to aggregation pheromone plus decomposed fruit as co-attractant in stone fruit orchards in Southern Australia.

Abstract

The response of Carpophilus spp. to 'attract and kill' stations that used aggregation pheromone plus fruit, which was progressively decomposed, as co-attractant was examined in Summer Fire Nectarine orchards. In the 1999/00 season, C. davidsoni was the dominant species (>90%) in the 'attract and kill' stations, whereas in 2000/01 C. hemipterus was dominant. In 1999/00, rotten fruit in the stations was replaced each week whereas in 2000/01 fruit was added to, instead of replacing, the rotten fruit. Although there were no significant differences in levels of damage, this work suggests that the quality of co-attractant had an important impact on the composition of species captured in the 'attract and kill' stations and the efficacy of the 'attract and kill' stations.
