(Coleoptera: Coccinellidae) were determined when feeding on five aphid species. Metopolophium dirhodum (Walker), Sitobion avenae (F), Rhopalosiphum padi (L.), Hyalopterus pruni (Geoffr.) and Myzus cerasi F (Homoptera: Aphididae) are widespread in Tekirdag, Turkey. Tests were carried out in a controlled environmental chamber (25+/-1degreesC temperature, 65+/-50% relative humidity and 16 h light:8 h dark period). Developmental times for A. bipunctata and C. septempunctata larvae varied significantly depending on species of aphid prey (P < 0.05). Development time (+/-S.E) varied from 17.50+/-0.84 to 20.83+/-1.60 days for C. septempunctata and 16.7+/-0.76 to 20.7+/-1.03 days for A. bipunctata. Mortality of A. bipunctata (50%) and C. septempunctata (63%) were highest on H. pruni.en10.1080/0958315031000124477info:eu-repo/semantics/closedAccessAdalia BipunctataCoccinella SeptempunctataMetopolophium DirhodumSitobion AvenaeRhopalosiphum PadiMyzus CerasiHyalopterus Pruni PreyDevelopmentMortality RateSpecificityArticle134449453Q2WOS:0001841354000072-s2.0-0038379828Q2
