Field evaluation of the efficacy of zingerone and other chemical lures on seven species of fruit fly in Sydney, New South Wales, Australia.

Abstract

Chemical lures are a vital component of many surveillance programs to manage tephritid fruit fly incursions. Increasing the efficacy of lures can greatly improve the detection and management of fruit fly incursions. We evaluated the efficacy of a new lure – zingerone, against cuelure, capilure and methyl eugenol in attracting fruit flies at twelve trapping sites in Sydney. Traps were monitored fortnightly for two years (2011-2012). Traps baited with zingerone captured a greater diversity of fruit flies than those containing the other lures. In comparison to cuelure, zingerone captured similar numbers of Dacus absonifacies (May) (Diptera: Tephritidae) and Dacus aequalis Coquillett (Diptera: Tephritidae), but captured significantly fewer Bactrocera tryoni (Froggatt) (Diptera: Tephritidae). Zingerone was ineffective at attracting Bactrocera cacuminata (Hering) (Diptera: Tephritidae), a methyl eugenol-responding species. Zingerone is a specialist lure for Bactrocera jarvisi (Tyron) but none were trapped in Sydney. In contrast to a previous study, our results found zingerone attracted fewer B. tryoni compared to cuelure traps but would still be considered an effective attractant. Additionally, zingerone may be better at attracting more species overall. Implications for monitoring programs are discussed. Further, the distribution of fruit fly species in Sydney is reviewed.
