Description:
Mayflies Timpanoga hecuba, caddisflies Dicosmoecus gilvipes, mosquitoes Culex peus and midges Cricotopus sp. were tested in the laboratory to determine the effects of air-supersaturated water on survival and adult emergence. The acute 96-hour LC50 value (lethal concentration which killed 50% after 96 hr) for mayflies was 128.9% saturation. Times to death and mean times to 50% death were determined. Adult midges and mosquitoes emerged at 141% and 143%, respectively. Good survival and emergence occurred in controls for all test groups.
