Abstract

During the 2012 and 2013 researches are conducted on the leaf aphids (Homoptera: Aphididae) and their predators in wheat (Triticum aestivum L.) and weeds from Poaceae family. Four aphid species were determined in the wheat, including: Sitobion avenae Fabr., Metopolophium dirhodum Walk., Shizaphis graminum Roud. and Ropalosiphum padi L. in both years of examinations. On the weed vegetation from Poaceae family, in 2012 and 2013 the same aphids species are found, except Metopolophium dirhodum Walk., that was not registered in 2013. Five predator species in colonies of leaf aphids in wheat, over two years of research were identified: Coccinella septempunctata L. (Coccinellidae, Coleoptera), Adonia variegata Gz. (Coccinellidae, Coleoptera), Adalia bipunctata L. (Coccinellidae, Coleoptera), Chrisopa carnea Steph. (Chrysopidae, Neuroptera) and Scaeva pirasti L. (Syrphidae, Diptera). On the weed vegetation, from predators, only Coccinella septempunctata L. was registered, and only on two weed species from Poaceae family: Lolium sp. in 2012 and Poa sp. in 2013.
