(Entomological Soc Turkey, Ege Univ, 2024) Sahin, Suemeyye Betul; Senol, Ozhan
The biological features of aphids as holocentricity, parthenogenetic reproduction, and telescopic generation have fascinated researchers to conduct chromosomal studies. Because of their chromosomes' holocentricity, the fragmentation fusion leads to karyotypic variations in aphid species. In phytophagous insects like aphids, holocentrism can be related to production of compounds that induce chromosomal variations. In the current study, the evaluation of karyotypes of six aphid species belonging to six genera that infest different host plants at the Ni & gbreve;de & Ouml;mer Halisdemir University campus area was conducted between September and November 2022. Evaluated species were Acyrthosiphon ( Acyrthosiphon ) ilka Mordvilko, 1914, Aphis ( Aphis ) spiraecola Patch, 1914, Brachycaudus ( Brachycaudus ) helichrysi (Kaltenbach, 1843), Cinara ( Cinara ) curvipes (Patch, 1912), Macrosiphum ( Macrosiphum ) rosae (L., 1758), and Pterochloroides persicae (Cholodkovsky, 1898). The C. curvipes and A. ilka karyotypes were determined for the first time in this study.
