Karyotype studies on some commonly occurring aphid species

Abstract

Karyotypic analysis was carried out from ten most commonly occurring aphids, namely Aphis gossypii (2n=8), Aphis nasturtii (2n=8), Aulacorthum solani (2n= 10), Aulacorthum sp. (2n=12), Greenidea formosana (2n= 18), Macrosiphoniella sp. (2n=12), Macrosiphum rosae (2n=10), Myzus persicae (2n=12), Rhopalosiphum maidis (2n=8) and Toxoptera aurantii (2n=8), infesting different host plants from Kangra and Shimla regions of Himachal Pradesh, India.

The karyotype studies of some aphid species (Aphidoidea: Hemiptera) from Niğde province in Türkiye

“…However, all other families are too poorly studied to allow the determination of standard values (Manicardi et al, 2015;Kuznetsova et al, 2021). In previous studies, diploid chromosome numbers of A. spiraecola (Kapoor, 1994;Blackman & Eastop, 2024), B.helichrysi (Raychaudri & Das, 1987Blackman & Eastop, 2024), Macrosiphum rosae (Samkaria et al, 2010;Blackman &Eastop, 2024) and Pterochloroides persicae (Blackman & Eastop, 2024) were determined as 8, 12, 10 and 20, respectively. The current study evaluated the karyotypes of six species that preferred different host plants and the chromosome numbers of them varied from 9 to 12.…”
