Extract

The parasites and predators found attacking the Aphids, Myzus persicae, Macrosiphum solanifolii and Aulacorthum solani, during field survey work of potato Aphids in the Northern Agricultural Advisory Province during 1944 and 1945, are treated individually, receiving the proportionate attention which their occurrence merits.

Aphidius avenae was the most important primary parasite, and in potato seed growing areas, the only one; while Asaphes vulgaris in particular, augmented by Lygocerus testaceimanus composed the majority of hyperparasites. The effect and relative importance of both types of parasite upon the Aphid populations of the survey are discussed with their percentage figures.

Predacious Syrphids included Platychirus manicatus and P. immarginatus whose life-histories were previously unknown; feeding records are also given for these two, and the former species accompanied invariably by P. scufatus occurred regularly on potatoes. More unusually, but often more effectively, Syrphus balteatus appeared. Other species were found.
