THE POPULATION DYNAMICS OF APHIDS COLONISING THE SHRUBS OF ROSA CANINA L. IN URBAN CONDITIONS OF LUBLIN
Bożenna Ja¶kiewicz
ABSTRACT
Studies on the species composition and population dynamics of aphids colonizing the shrubs of Rosa canina L. were conducted in the years 1999-2001 in the urban conditions of Lublin. The shrubs growing in two sites: a street (A) and a park (B) ones were selected for observation. Eight aphid species were found on rose shrubs as a result of studies, namely Myzaphis rosarum (Kalt.), Macrosiphum rosae (L.), Metopolophium dirhodum (Walk.), Chaetosiphon tetrarhodus (Walk.), Aphis fabae Scop., Maculolachnus submacula (Walk.), Longicaudus trirhodus (Walk.), Macrosiphum euphorbiae (Thom.). Those aphids were more numerous in the street site (A). Their population dynamics was affected by weather conditions, especially heat periods and stormy rainfalls.
Key words: aphids, Rosa canina L., population dynamics, weather conditions..
