Condition of <i>Bombus impatiens</i> colonies that had been exposed to insecticide-treated turf with flowering white clover for 6 days, after which they were moved to an insecticide-free site to openly forage for 6 weeks before this evaluation.^a

The turf was lightly irrigated after insecticide application; the surface had thoroughly dried before bees were introduced. aData are means (± SE). ANOVA (df = 2, 18): live, F = 2.31, P = 0.13; dead, F = 0.92, P = 0.42; % dead, F = 0.93, P = 0.41; wt live adults, F = 1.8, P = 0.19; live immature, F = 2.45, P = 0.12; dead immature, F = 0.90, P = 0.42, honey pots, F = 2.31, P = 0.13, hive wt, F = 2.27, P = 0.13. P-values from pre-planned linear contrasts between clothianidin versus untreated were 0.053, 0.23, 0.27, 0.28, 0.20, 0.09, 0.09, and 0.058, respectively. For chlorantraniliprole versus untreated, they were 0.15, 0.29, 0.95, 0.29, 0.51, 0.27, 0.18, and 0.67, respectively. blarvae, pupae, and fully-formed workers and males still enclosed in the pupal exoskeleton within the cell. cadult workers, males, and queens.
