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