The Distribution of Cimex lectularius in Towns in England and Wales

Abstract

A brief historical account of Cimex lectularius in England is followed by an analysis of numerical data regarding infestation in twenty-three towns in England and Wales. The data indicate that in the majority of cases the degree of infestation increases along with the order of magnitude of the town ; one or two exceptional cases are discussed. Comparison of the figures for inland towns and seaports suggests, though more data are desirable, that a low degree of infestation is common in the former whereas the majority of the latter show a moderate or heavy infestation.
