Determination of aphid species and its parasitoids-predators with population development of aphis illiniosensis in grapevines of mersin province

This study was carried out to determine pest aphid species in vineyards and their parasitoids-predators and follow the population dynamics of Grapevine aphid [Aphis illinoisensis (Shimer) (Hemiptera: Aphididae)] during growing period in vineyards at Mersin province. As a result of this study, three different aphid species were determined namely, Aphis illinoisensis Shimer, Aphis fabae Scopoli, Myzus persicae Sulz. (Hemiptera: Aphididae); Coccinellids, Coccinella septempunctata (L.), Oenopia (Synharmonia) conglobata (L.), Hippodamia (Adania) variegate (Goeze), Adalia fasciatopunctata revelierei (Mulsant), Cheilomenes propingua (Mulsant), Scymnus frontalis (Fabricius), Scymnus pallipediformis (Günther) (Coleoptera: Coccinellidae); Syrphids, Episyrphus balteatus De Geer, Metasyrphus corollae (F.) (Diptera: Syrphidae); Chrysopids, Chrysoperla pallida Henry, Cunctochrysa baetica Hölzel (Neuroptera: Chrysopidae) and parasitoids Aphidiidae, Aphidius matricariae Haliday (Hymenoptera: Aphidiidae). In addition hyperparasitoids, Syrphophagus aphidivorus Mayr (Hymenoprera: Encyrtidae) and Pachyneuron aphidis Bouche (Hymenoprera: Pteromalidae) was determined. The population development of A. illinoisensis was studied on two different grapevines in Mersin. First aphid population on grapevines was determined in the middle of April and it reached the highest population density in the middle of May, at that time the temperature was over 20-21 °C, relative humidity %70-76. A. illinoisensis was damaged when the first shoot was grown and flowering period. It was also determined that A. illinoisensis wasn?t occur intensive population.
