HIS 2129 Chapter Notes - Chapter 7: Dieldrin, Scarabaeidae, United States Public Health Service
Document Summary
Direct killing of birds, mammals etc. by chemical insecticides sprayed on land. Dilemma of wildlife loss: conservationists assert severe losses, control agencies deny any such losses. Professional wildlife biologist is the best qualified to discover and interpret wildlife loss. Entomologist is not disposed to look for side effects of his control program. Even though some species are able to replenish the area after being sprayed away, a great deal of harm has still occurred re-establishment is rare. 1959 27,000 acres in michigan sprayed with aldrin to control the japanese beetle this puts the population, domestic animals and wildlife at risk of exposure to these harmful chemicals. Nickell, naturalist, stated that japanese beetles were not increasing in numbers but have been present in the area for 30 years. The government stated that aldrin was a poisonous chemical but would do no harm to humans or their plants/animals.
