oa Journal of the Entomological Society of Southern Africa - The artificial conditioning of lepidopterous larvae for attack by ectoparasitic ichneumonid larvae

Abstract

Several species of codling moth parasites are being reared in the laboratories of the Fruit Research Station on larvae and pupae of the codling moth or on alternate host species in connection with biological control experiments. While the provision of host material in quantity is obviously a primary consideration, the question of efficient utilization of the host is scarcely less important.
