[Insecticide resistance in bedbugs(Cimex lectularius) in Korea]
In the summer of 1969 from July through October, authors carried out a study of susceptibility in adult female bed bug(Cimex lectularius) in order to ascertain any development of resistance to insecticides in Korea. The test to DDT and Dieldrin was performed in laboratory by the continuous exposure of residues method, with standard impregnated paper used for adult mosqitoes. Some results so far obtained can be summarised as follows: 1. LC(50) were 2.839% in DDT and 0.167% in Dieldrin. 2. The resistance has been arisen 2.4~2.9 times in DDT and 1.6~2.4 times in Dieldrin as compared with London laboratory strain, but they were susceptible 1.4 times in DDT and 180 times in Dieldrin as compared to Israel resistance strain.
