Abstract

Susceptibility of four bee species (Hymenoptera: Apoidea) to field weathered insecticide residues.

Abstract

Studies showed that deltamethrin, methamidophos, methidathion, methyl parathion [parathion-methyl], permethrin, phosmet, pyridaben, thiocarb, and trichlorfon can all be applied in late evening with minimal hazard to bumble bees (Bombus occidentalis); deltamethrin, formetanate, pyridaben and thiocarb can be applied in late evening with minimal hazard to honey bees (Apis mellifera); deltamethrin, pyridaben and trichlorfon can be applied in late evening with minimal hazard to alkali bees (Nomia melanderi); and deltamethrin, pyridaben and trichlorfon can be applied in late evening with minimal hazard to alfalfa leafcutter bees (Megachile rotundata). In general, the typical pattern of bee susceptibility to insecticide residues was M. rotundata > N. melanderi > A. mellifera > B. occidentalis.
