Jackson trap efficiency capturing <i>Bactrocera dorsalis</i> and <i>Zeugodacus cucurbitae</i> with male lures with and without insecticides

Abstract Jackson traps baited with male lures or without insecticides are essential components of surveillance and monitoring programmes against pest tephritid fruit flies. The ability a trap to capture fly that enters, sometimes termed ‘trap efficiency’, is dependent on many factors including the trap/lure/toxicant combination. We tested effects three important efficiency two species, using ‘standard’ (i.e. as they used in state‐wide programme California) alternative setups: Insecticide (Naled, DDVP None), type adhesive sticky panel (Seabright Laboratories Stickem Special Regular HiTack) use single combination lure (Methyl eugenol and/or cuelure). Experiments were conducted large outdoor carousel olfactometers known numbers Bactrocera dorsalis Zeugodacus cucurbitae by trapping wild populations same species. Lures aged out eight weeks develop comprehensive dataset various combinations. Results indicate current liquid lure/naled combinations cotton wicks California for these flies can be effectively replaced plastic polymer plugs pre‐packaged strips no loss longer. ‘high tack’ showed advantage over standard flies, both have low when an insecticide trap. Combination + varied compared naled: Olfactometer assays similar between them B. , but higher wafer Z. . Field result slightly performance much lower catch
