The whitefly Bemisia tabaci (Gennadius) (Hemiptera, Aleyrodidae) is one of the most crucial agricultural pests in tropical and subtropical regions. The pest is a species complex which contain morphologically indistinguishable biotypes or genetic groups. The aim of the present study is to examine B. tabaci populations collected from Aydin, Antalya, Mersin, Adana and Hatay regions in 2004 and 2005. Prior to analysis, as the first step, the biotypes were determined by considering molecular differences among populations. In addition, the differences among populations were determined by means of bi ...Daha fazlası
