ABSTRACT

The studies concerning the species composition and population dynamics of aphids inhabiting the shrubs of Cotoneaster divaricatus Rehder et E.H. Wilson were conducted in two sites: street site (A) and park site (B) on the green areas of Lublin in the years 1999-2001. Three species of aphids, namely Aphis pomi De Geer, Aphis fabae Scop. and Rhopalosiphum insertum (Walk.) were found on examined shrubs. All aphids species occurred in greater number in park site (B). A. pomi was the most numerous aphid species in both sites. Hot summer with air temperatures above 30°C and stormy rainfalls clearly decreased number of all aphid species.

Key words: aphids, Aphis pomi De Geer, Aphis fabae Scop., Rhopalosiphum insertum (Walk.), Cotoneaster divaricatus Rehder et E. H. Wilson, population dynamics..
