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

Abstract

ABSTRACT It has generally been supposed that the uptake of large quantities of plant sap by aphids is the direct result of suction. Zweigelt (1914) has questioned this concept, and Kennedy &amp; Mittler (1953) have thrown further doubt on the supposition that aphids are typical ‘sucking’ insects. The present paper sets out results, obtained in a study of the uptake of phloem sap by Tuberolachnus salignus (Gmelin), which may help to clarify this question.
