    Description

    Two commercial preparations of Bacillus thuringiensis (Bet.) were aerially applied in 1980 to populations of spruce budworm (Choristoneura fumiferana (Clem.)) in Arizona, Maine, New Hampshire, and Wisconsin. Operations were conducted under the auspices of CANUSA-East with standardized procedures for spray application and population monitoring. The 8 Billion International Units (BIU) Dipel® and Thurlcide® formulations are effective and similar for spruce budworm control when applied under favorable conditions. This paper compares results between locations and critiques the experimental design, spray operations, and data collection procedures.
