Studies on the population dynamics of aphids Cinara juniperi De Geer on the shrubs of Juniperus communis L. in the urban conditions of Lublin were conducted in the years 2002–2004 in two types of sites: a street one and a park one. The first individuals of this species were most frequently observed at the turn of April and May, while the maximum population was found in the first half of May. The course of the weather conditions affected the population dynamics of aphids. Those insects were observed in much bigger numbers on the shrubs growing in the street site. The preying of C. juniperi caused
browning and drying out of the needles and inhibition of the stem growth, which had an influence on lower decorative character of the examined plants.
