Abstract

In 1987 the impact of aerial application of ethyl parathion to waterfowl on small prairie wetlands adjacent to sunflower fields in North Dakota was assessed by studying 5 fenced wetlands surrounded by sunflowers and 5 fenced controls. By 3 days post-spray, 4 of 104 ducklings released onto the wetlands were alive, compared to 52% of 105 control ducklings. Brain ChE activity was depressed > 50% in all but one of the 50 ducklings found dead post-spray. Survival of amphipods in enclosures within the contaminated wetlands was reduced for 25 days. Naturally-occurring broods on unfenced wetlands and free-living aquatic invertebrates in the fenced wetlands were also severely affected. The results suggest aerial application of insecticides may have significant direct and indirect impacts on the survival of adult and juvenile waterfowl within the prairie-pothole region.
