Abstract
This paper presents the chromosomal analysis of three aphid species collected from orchards of Shimla, Himachal Pradesh, belonging to the following two subfamilies: Aphidinae and Calaphidinae. Chromosomal studies revealed the highest reported diploid number (2n) as 12 in Myzus persicae collected from the Apricot plant, and the lowest reported diploid number (2n) as 8 in Aphis craccivora and Chromaphis juglandicola infesting Apple and Walnut plant respectively. For, the construction of karyotypes and idiograms, detailed information regarding the mean actual length, total complement length, and relative lengths of chromosomes was calculated by using a scale and ocular micrometer. The karyotypes show a gradual decrease in the lengths of the chromosomes.
Keywords:
Aphids, Karyotypes, Chromosomes, Idiograms, Relative lengths, Calaphidinae.
