Ethyl Nicotinate: A chemical attractant for Thrips obscuratus (Thysanoptra: Thripidae) in stonefruit in New Zealand [Apricots, peaches]

Ethyl nicotinate was found to be a potent attractant for Thrips obscuratus in peaches and apricots. The male-to-female ratio in traps was 1:8. The chemical was more attractive than ripe fruit, with peak catches at harvest. Season-long trapping showed the efficiency of the chemical compared to unbaited traps. The chemical remained attractive for at least 2 weeks when 50 mu l were placed in open 2-ml vial caps. Various pyralids, geometrids (Lepidoptera), and chironomids (Diptera) were also attracted in low numbers to ethyl nicotinate.
