Strawberry aphid, Chaetosiphon fragaefolii (Cockerell), is the most important vector of strawberry virus. Breeding of genotypes resistant to this pest is an important preventive control measure, which can be compatible with rational insecticide application. The aim of the paper was to determine effects of dimethoate and deltamethrin on C. fragaefolii populations reared on two strawberry genotypes different in susceptibility: susceptible strawberry cultivar Čačanska rana and medium resistant hybrid, zf/1/94/96 (Senga Fructarina x Del Norte). Lower toxicity of deltamethrin was observed (laboratory assay) as well as lower biological efficacy of dimethoate at lower concentrations (field trial) for specimens from C. fragaefolii population reared on susceptible strawberry cultivar Čačanska rana.
