Experiments were conducted to determine the effects of Btk (Dipel�8AF) at a concentration of 600 IU/ml to 12 taxa of aquatic insects in laboratory bioassays and in outdoor stream channels. No significant mortality was found in 11 species after 9 days, but Taeniopteryx nivalis had 30% mortality. In addition, Btk did not affect drift of any of the species tested.
The results of this paper showed that Btk is unlikely to directly affect aquatic insects
