Evaluating trap and lure combinations using Biotraps and Lynfield traps for the surveillance of Queensland fruit fly Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) and other tephritids in southern New South Wales, Australia

Abstract Fruit fly surveillance remains essential for international and domestic trade. The dry cuelure baited Lynfield trap has been the Australian standard since the early 1990s. Here, we tested the two versions of Biotraps against the Lynfield traps in the Riverina area of New South Wales. The Biotraps using a protein gel performed significantly better in trapping Island fly and female Queensland fruit fly. Also, Biotraps were assessed as at least equal to or superior to Lynfield traps for trapping male Queensland fruit fly. However, the number of Newman fly trapped exhibited no significant difference between the two trap types in both time periods A and B. We discuss differences in trap architecture, toxicants and lures between the two traps, along with benefits for storage and transport.
