Studies On the Feeding and Nutrition of <i>Tuberolachnus Salignus</i> (Gmelin) (Homoptera, Aphididae)

Abstract

ABSTRACT Since Tóth (1940) questioned that the dietary nitrogen supply of aphids is adequate for their growth and reproduction, considerable controversy has existed regarding the necessity and ability of aphids to supplement their dietary nitrogen supply with atmospheric nitrogen through the agency of their symbiotic micro-organisms. Few data are available, however, on the amounts of nitrogen actually ingested, excreted, and assimilated by aphids. The aim of the present investigation was to determine these data for Tuberolachnus salignus (Gmelin), and to resolve the controversy for this species.
