Feeding on insects makes insectivorous bats more likely to be exposed to insecticides. We sent nine bats (5 Indiana myotis, Myotis sodalis, and 4 northern myotis, Myotis septentrionalis) through U.S. Fish & Wildlife Service (USF&W) sources to be tested for toxicants. Three of these proved to have organophosphate (OP) insecticide residues: chlorpyrifos (0.18 [micro]g/g), diazinon (0.034 [micro]g/g), and methyl parathion (0.015 [micro]g/g). Chlorpyrifos was also detected in all six dead ...
