Title: Growth and developmental interactions in some aphids and their hymenopterous parasites
Abstract: The growth and development of apterous and alate morphs of viviparous pea aphids, Acyrthosiphon pisum, was compared with that of aphids parasitized at age 60 h by Aphidius smithi. The growth pattern, adult weight and time to reach the adult stage in A. smithi males were not affected by aphid morph. In unparasitized pea aphids, the dry-to-wet-weight ratio varied little during development and early adult life, while in parasitized aphids it increased in accordance with parasite development. It is proposed that, in parasites that develop in growing host stages, the development time and adult weight covary, both being influenced by the host's size at the beginning of parasitism and its capacity to grow during parasitism. The importance of developmental interactions for successful parasitism is discussed.
