Abstract
Aldrin, lindane and parathion reduced numbers of the sugar-beet root aphid, Pemphigus betae Doane, on sugar beets in greenhouse tests. In field tests there was an increase in yield of beets in both 1958 and 1959 at one of two locations when aldrin and parathion were applied to the soil. The increase appeared to result from aphid control early in the season. Both insecticides reduced the populations of the predator, Thaumatomyia glabra Meigen. By fall the large numbers of T. glabra present in the untreated plots had reduced the numbers or aphids to levels equal to or lower than those of insecticide-treated plots.This publication has 1 reference indexed in Scilit:
