The evaluation of karyotype variations of aphids that distributed in Niğde Ömer Halisdemir University campus area

While approximately 6000 aphid species are represented worldwide, it is represented by 671 species in our country. It infects many different host plant species in various ways, not only by feeding directly on plant sap, but also as an active vector of numerous plant viruses. In this study, 15 specimens from different host plants were sampled, but chromosomal data could only be obtained from six live adult females. Preparations for karyotype studies were carried out on parthenogenetic female viviparous individuals. In this study, it was aimed to carry out karyotype analyses of aphids distributed in the campus area of Niğde Ömer Halisdemir University and feeding on different host plants. The karyotype data of C.curvipes and A.ilka were given for the first time in this study as 2n=10 and 2n=8+X, respectively. Considering the geographical location of Turkey and the different climatic zones it has, it is thought that the chromosomal variations of aphids distributed in our country will be quite diverse.
