EXPERIMENTS WITH VOLATILE SUBSTANCES IN SLOW-RELEASE FORMULATIONS CAUSING REPELLENCY FOR OVIPOSITION BY THE CABBAGE ROOT FLY, PHORBIA-BRASSICAE BCHE (DIPT, ANTHOMYIIDAE)
H. Denouden et al., EXPERIMENTS WITH VOLATILE SUBSTANCES IN SLOW-RELEASE FORMULATIONS CAUSING REPELLENCY FOR OVIPOSITION BY THE CABBAGE ROOT FLY, PHORBIA-BRASSICAE BCHE (DIPT, ANTHOMYIIDAE), Journal of applied entomology, 115(3), 1993, pp. 307-312
For the purpose of causing repellency against oviposition of Phorbia b
rassicae 6 repellents in slow release formulations were tested. The be
st formulation showed an acceptable repellency for at least 5 weeks. S
uch a protection probable can be sufficient (e.g. for cauliflower) for
building up a resistance against the larvae of P. brassicae. Further
field experiments are needed for improving the carrier substances.
