Abstract
A method has been developed for the assay of the odorous attractant of the cockroach, P. americana. The method, called the counterpoint test, employs two matched groups of roaches and provides for a simultaneous titration of standard and unknown. It has a statistical error of ±40 per cent at a level of significance of 95 per cent.
