| Abstract: | 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. |
