Abstract:

Adults of Diabrotica virgiferaLeConte were collected annually from 1963 through 1972 from 18 specific sites in Nebraska and treated with a series of concentl'l1tionsof diaziuon and phorate to determine annual median lethal dose values. Dosage-mortality curves or regression lines were statist- ically determined from the annual median lethal dose data. Although the median lethal dose values for both insecticides increased from 1963 to 1972, neither regression line is significant. However, the median lethal dose data for diazinon significantly fit a quadratic curve, indicating possible reversion in susceptibility to diazinon. Predictions of imminent resistance in the field based on the slopes of the regression lines would be speculative.
