Bio-efficacy of commercial insecticides against bed bug (Cimex lectularius)

In the early 1990s, bed bug infestations began to be seen an increase across the nation. In Japan, the occurrence of bed bug is also increasing in hotels or apartment houses. In this study, we evaluated insecticidal activity of Pyrethroids, Organophosphates and Carbamate which are commercialized in Japanese market for controlling the bed bug. Most of the active ingredients are available in other countries. In topical application test and filter paper contact test, d-d-t cyphenothrin and fenitrothion showed high killing activity. In oil spray tests, imiprothrin showed the highest knock down activity. Therefore, the combination use of d-d-t cyphenothrin and imiprothrin or fenitrothion and imiprothrin might be effective in the bed bug control.
