Abstract
The efficacy of eight insecticides which are used as household and hygiene insecticides in Japan were evaluated against susceptible strain of bedbug (Cimex lectularius L.). d-d-t Cyphenothrin and fenitrothion showed high efficacy among the six insecticides (d-d-t cyphenothrin, permethrin, d-phenothrin, fenitrothion, propoxur and metoxadiazon) by topical application test and filter paper contact test. By the test of oil formulation, imiprothrin showed the highest knock down activity and permethrin showed the highest killing efficacy among the three insecticides (permethrin, imiprothrin, d-tetramethrin).
