A survey of bed-bug resistance to insecticides in Israel

摘要

Fourteen strains of bed-bugs collected from various places in Israel and one normally susceptible strain from the laboratories of J. R. Geigy S.A., Basle, Switzerland, were tested for their resistance to DDT and gamma-BHC. A very high degree of resistance to DDT was found in most of the strains, indicating that DDT-resistance is very widespread in Israel. A moderate to low resistance to gamma-BHC was observed in several strains.
