Effects of a carbaryl-induced depression in invertebrate abundance on the growth and behavior of American black duck and mallard ducklings

摘要: Aerially spraying ponds with carbaryl (Sevin-4-oilR) at 840 g active ingredient/ha reduced biomass and numbers of macroinvertebrates decreased the growth rates American black duck, Anas rubripes, mallard. platyrhynchos, ducklings in Maine. Ducklings on sprayed spent more time searching for food less resting, their rate movement around was greater than unsprayed ponds.
