Abstract: Pepper is a crop infested by a great number of pests during the vegetation period. The most frequently met pests are green peach aphid (Myzus persicae Sulz.), thrips (Frankliniella occidentalis Perg. and Thrips tabaci Lindeman) and cotton bollworm (Helicoverpa armigera Hubn.). The resistance of the plant-host to the pests is a desired feature that could ensure limitation of the infestation and obtaining of quality produce. It was made a screening for pest infestation in 98 pepper (Capsicum spp.) accessions– varieties, breeding line, local forms and local varieties, grown on open field at natural background of infestation.
