Extract

A spray chamber provides an efficient means for screening promising insecticide compounds, a procedure that oftentimes serves as a useful preliminary to field tests, which are more expensive and less controllable. In research with residual insecticides for controlling bark beetles, we found a need for rapidly reproducing insecticide deposits on sections of fibreboard to test their toxicity. A spray chamber was constructed for this purpose. Its design and operation are described here.
