Sažetak
Abundance and diversity of aphid and coccinellid species were monitored in apple orchards in Urmia during 2010 and 2011. In this study, eight aphid species were collected and identified in 2010 and nine were found in 2011, while only two coccinellid species were found in both years. In 2010, Aphis pomi (De. Geer) was the most abundant aphid (55.5%) followed by Dysaphis plantaginea (Passerini) (34%). However, in 2011, Eriosoma lanigerum (Hausmann) had the largest population (57%) in apple orchards followed by D. plantaginea (21.5%) and A. pomi (18%). Generally, more aphids were collected in June and July of 2010. However, aphid’s population in 2011 was high from mid-May until early October. Shannon and Simpson diversity indices were measured. The Shannon and Simpson indices of aphids and coccinellids in 2011 were more than those in 2010. Simpson index of aphids in 2010 and 2011 were 0.573 and 0.594, respectively, indicating that the possibility of selecting two different species of aphids was 57% in 2010 and 59% for 2011.
