oa Journal of the Entomological Society of Southern Africa - A study of Insecticide resistance in a population of Bed bugs, Cimex lectularius L., and a method of assessing effectiveness of control measures in houses



Prior to the development of the synthetic chlorinated hydrocarbon insecticides, fumigation with hydrocyanic acid was commonly employed for the control of infestations of the bed bug, Cimex lectularius L. The introduction of the highly persistent insecticides DDT, gamma BHC and dieldrin rapidly replaced HCN fumigation and resulted in a marked decrease in bed bug infestations throughout the world. However, as in the case of many other species of insects, continual use of the chlorinated hydrocarbon insecticides has resulted in the development of insecticide-resistant bed bug populations. DDT resistant bed bug populations were first reported from Hawaii in 1943 (Johnson and Hill, 1948), and later in Israel (Cwilich and Mer, 1957).
