The hazard of naled (1,2-dibromo-2,2-dichloroethyl dimethyl phosphate) and Zectran® (4-dimethy-lamino-3,5-xylyl methylcarbamate) to forest birds and mammals was studied. Experimental applications for the control of spruce budworm (Choristoneura occidentalis) in Montana and Idaho included one application of naled at 0.4 pound per acre, and four Zectran applications at 0.15 pound per acre or less during a 3-year period. Naled was less effective than Zectran, which was the most promising material found in a search for less persistent and safer insecticides than DDT. We compared bird and mammal counts and observations made before and after treatment on 20-acre plots within both treated and untreated areas, and found no apparent harmful ejects of naled and Zectran on birds and mammals studied. The use of the aerosol system of spraying reduced the contamination of the environment by reducing the deposit.
