Five series of tests were conducted with insecticides applied to 0.01 acre plots of alfalfa. Treatments were made with a hand sprayer, using 25 psi pressure and applying 25 gal/acre. Residual test exposures were replicated 4 times by caging 50-100 honey bees (HB), 15-30 alkali bees (AB), or 20-40 alfalfa leafcutting bees (LB) with each of 4 samples per treatment and time interval. HB were placed in petri dish cages with screen inserts, fed sugar syrup, and held at 75-78°F. AB and LB were placed in petri dish bottoms covered with screened plates, fed honey syrup, and held at 85-88°F.
