Abstract

The common bed bug, Cimex lectularius (Linnaeus 1758), is a nocturnal blood-sucking ectoparasite of humans that is highly prevalent in the northeast of Iran. In recent years, the efficacy of those insecticides that have been frequently used to control bed bugs in Iran has not been studied. Due to frequent complaints about bed bug treatment failures in Mashhad city (northeastern Iran), this study assessed the susceptibility of C. lectularius collected from a student residence hall to Diazinon, Malathion, and λ-cyhalothrin. The desired concentrations of each insecticide were prepared in acetone, and bioassays were performed using insecticide-impregnated filter paper method. The concentration-response data were subjected to POLO-PC software and data were analyzed by the log-probit procedure. The LC50 values of Diazinon and λ-cyhalothrin for examined bed bugs were 1,337.40 and 2,022.36 ppm, respectively. Malathion at the highest concentration (10,000 ppm) did not exhibit any toxicity to examined C. lectularius. Comparing these results to the same previous studies showed that susceptibility of examined bed bugs to these insecticides has been highly decreased. This study revealed an occurrence of insecticide resistance in bed bug populations in northeastern Iran. It also suggests that Malathion, Diazinon, and λ-cyhalothrin are ineffective against bed bugs in this region. © Crown copyright 2019.
