Aphid Parasites Collected in New Brunswick in 1950

Abstract
Since 1934, when studies of aphids infesting potatoes were begun in New Brunswick, it has been observed that a large number of potato aphids are attacked by parasices each season. More attention was given to parasitized aphids in 1950 than in previous years, in a study of parasitism as a factor in aphid control. In this paper are recorded the parasites reared from aphids collected on potatoes and other hosts in New Brunswick in 1950.
