Karyotypic Studies in Twenty-seven Species of Aphids (Homoptera: Aphididae) from India

Abstract

The somatic karyotypes of twenty-seven species of aphids belonging to 5 Sub-families have been described. The majority of the aphid species were collected from various hostplants in different regions of the North-Eastern India and a few of them from the North-West India. An attempt has been made to evaluate the present state of karyotypic knowledge and the karyoevolutionary trend in these five Sub-families of Aphididae.
