Notes on Apanteles sesamiae, Cam., a Parasite of the Maize Stalk-borer (Busseola fusca, Fuller) in South Africa

Abstract

1. Apanteles sesamiae, Cam., is the only parasite of Busseola fusca, Fuller, which is of importance in the Eastern Transvaal.2. The adult is described, and the morphology of the last stage larva of the parasite is discussed in detail.3. The biology and bionomics of the species are dealt with, and the effect of parasitism on the host is described.4. The extent of natural parasitism and the rapidity of increase in the field shows that A. sesamiae is an effective parasite of the Maize Stalk-borer in South Africa.5. The results of cold storage experiments are given and the methods of shipping parasite material are described. It was found impracticable to ship cocoons, but successful consignments of parasitised borer larvae were sent to Canada.
