- Abstract
Abundance and species diversity of aphids and ladybirds in three wheat fields located in Urmia city were studied in 2010 and 2011. Samplings were conducted with 120 plants in the wheat fields from mid-April to late July. Species richness was measured using Shannon and Simpson indices. Six aphid species (Aphididae) and five coccinellids (Coccinellidae) were identified in the fields. Among the collected aphid species, Schizaphis gramimun (Rondartii) and Metopolophium dirhodum (Walker) were most abundant in the fields. For coccinellids, Coccinella septempunctata L. was the most abundant species. Highest aphid species diversity was observed on 17 April 2010. No aphid species was found after 15 July of both years.
