Description: Six insecticides were tested in the laboratory as aerosols against larch casebeare1 larvae. Their toxicity was determined by both direct contact and residual contact on filter paper. All six were highly toxic at less than 1.05 µg/ cm2 (the equivalent of 1.5 oz./acre). In decreasing order of toxicity at LD90 (direct contact) the insecticides tested were: Zectran, malathion, Sumithion (0.24 - .26 oz./acre), pyrethrins, Matacil (0.45 - .5O oz./acre), and Gardona (1.4 oz./acre). For field trial of the three most toxic materials, a dosage of 2 oz./acre is suggested.
