Abstract
WHEN considering the performance of solid insecticides of the chlorinated hydrocarbon type, such as DDT, γ-BHC and dieldrin, a factor frequently considered is the toxic properties of the vapours from crystalline deposits. To assess this factor biologically, both in the laboratory and in the field, the commonest practice is to keep cages holding test insects a short distance from the treated surface. The toxic effect found after such an exposure is generally referred to as the ‘vapour toxicity’.
