title: Apparatus for evaluating vapor-induced dispersal of Blattella germanica (Dictyoptera: Blattellidae).
abstract: An apparatus for evaluating vapor-induced dispersal of Blattella germanica (L) is described. It is made of two 750-ml crystallizing dishes connected by a glass and wire mesh tube. Its use is illustrated by experiments on exposure of late instars to vapors of a propoxur in oil formulation and those of its solvent system.
