Abstract
While DDT in oil solution is widely and successfully used against many forest insects at the rate of 1 pound in 1 gallon per acre, little is known of the relative effectiveness of other insecticides for this purpose. Laboratory tests are described in which BHC with and without an extender, aldrin, dieldrin, and endrin were compared with DDT in their effectiveness against spruce bud worm (Choristoneura fumiferana (Clem)). In some tests larvae DDT foliage were treated while in others foliage was treated then weathered before larvae Were placed in it. Each insecticide was applied in two dosages. In every test DDT was superior.
