Experimental evaluation of insecticide efficacy in controlling Brevicoryne brassicae L. in cabbage

Cabbage aphid (Brevicoryne brassicae L.) is an important and highly destructive insect pest of cabbage in Serbia. It is capable of inflicting serious crop losses on cabbage and other brassica crops in some seasons, especially during periods of drought. The aphid is also a vector of viruses causing cabbage diseases and it must therefore be eliminated as a source of infestation. Employing appropriate EPPO methods, this study aimed to evaluate the biological efficacy of four insecticides in controlling B. brassicae and to determine possibilities for their use in practice. Among the tested insecticides, dimethoate and pirimicarb had been in use in the past, while acetamiprid and triazamate are new products. All tested products showed high levels of biological efficacy in the localities studied. The insecticidal products were mostly found to have 100% efficacy.
