Laboratory evaluation of some pesticides on the cabbage aphid, Brevicoryne brassicae L. and their side effects on some important natural enemies
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 65 (1), 16-19
Abstract: The susceptibility of adults of the cabbage aphid, Brevicoryne brassicae and two of the most important predators, Coccinella undecimpunctata and Chrysopa carnea to pesticides was assessed. Most of the organophosphorus and carbamate compounds tested were toxic to the aphids. Profenophos was highly toxic to the adult virginoparous aphid at Lc50 level. Malathion demonstrated the highest toxicity to, the aphids.
The application of profenophos for the cabbage aphid at Lc50 level exhibited no toxicity for Coccinella but was highly toxic for Chrysopa. Pirimicarb proved to be the most selective of the compounds tested for the control of aphids when it was used at a concentration that caused 50% mortality as it was found to be unharmful to both Chrysopa and Coccinella. Dimethoate, on the other hand, was found to be very harmful and highly toxic to both Coccinella and Chrysopa adults and would probably be destructive to those natural enemies in the field.
Laboratory evaluation indicates that both pirimicarb and malathion have potentials for use, in IPM program for vegetable pest control.
