Li and Fitzpatrick (1997) found that the addition of 5% Pheast to B. thuringiensis based insecticides increased the mortality of Choristoneura rosaceana (Harris) larvae fed leaves of raspberry plants, Rubus idaeus L. (Rosaceae), treated with these insecticides in the laboratory. We report results from a test of the effectiveness of Pheast when exposed to field conditions and fed to larvae in the laboratory.
