Summary
Traps baited with synthetic aggregation pheromones of Carpophilus hemipterus (L.), C. mutilatus Erichson and C. davidsoni Dobson and a fermenting coattractant, were used to identify the fauna and monitor the seasonal abundance of nitidulids in orchards in five horticultural regions in Australia (Tumut-Batlow (New South Wales), Swan Hill (Victoria), Stanthorpe, Nambour (Queensland) and Manjimup, (Western Australia). Six species of Carpophilus were trapped (C. hemipterus, C. mutilatus, C. davidsoni, C. humeralis (F.), C. gaveni Dobson, C. marginellus Motschulsky), plus at least two unidentified species. C. davidsoni dominated the trapped nitidulids in all regions except Manjimup. C. hemipterus was common at Swan Hill. C. mutilatus was common at Stanthorpe and was the dominant species trapped at Manjimup. Only small numbers of C. gaveni, C. humeralis, and C. marginellus were trapped and these were generally most common at the Queensland sites. Peak abundance of nitidulids usually occurred during late spring, and summer populations in inland areas were usually small. The nitidulid fauna in these regions is discussed with respect to management using synthetic aggregation pheromones.
