Abstract Effects of dipterex, temephos and chlorpyrifos resistance on the relative fitness in Culex pipiens pallens were evaluated in terms of developmental and reproductive characteristics. Life tables of Dip‐R (dipterex), Tem‐R (temephos), Chl‐R (chlorpyrifos) resistant strains and susceptible strain (S) were also constructed to determine the relative fitness by the net reproductive rates (r). The results indicated that three OP‐resistant strains possessed reproductive and developmental disadvantages involving in bloodsucking ratio, average oviposition rate and survival ratio relative to the S strain. The Dip‐R, Tem‐R and Chl‐R strains had the relative fitness value of 0. 542, 0. 631 and 0.618, respectively.
