"The cholinesterase-inhibiting insecticide Zectran® is currently being tested for spruce budworm (Choristoneura fumiferana) control in Canada. Because of its relatively high acute oral toxicity to birds, concern about Zectran' s registration prompted the Canadian Wildlife Service (Atlantic Region) to determine if field application of it is hazardous to songbirds. Of particular concern are nestlings, which are more sensitive to cholinesterase-inhibiting insecticides than are adult songbirds"--Abstract, p. 3.
