Abstract
The responses of Dasineura brassicae and its parasitoids Platygaster subuliformis and Omphale clypealis to allyl and 2-phenylethyl isothiocyanates have been investigated using a new design of trap in winter oilseed rape. Traps baited with allyl isothiocyanate caught more male and female D. brassicae and more female O. clypealis than traps baited with 2-phenylethyl isothiocyanate or unbaited traps, whereas traps baited with 2-phenylethyl isothiocyanate caught more male and female Platygaster subuliformis than traps baited with allyl isothiocyanate or unbaited traps. The implications of these results for host-plant and oviposition-site location by D. brassicae and for host habitat and host location by the parasitoids are discussed, as is the potential for using these responses in integrated pest management strategies.
