Objective To investigate the population densities and insecticide resistance level of Culex pipiens pallens in the lakeside area of Weishan Lake in Shandong province, China, before and after new countryside development. Methods Xicun village and Shizhuang village at the lakeside of Weishan Lake were used as countryside construction sample and control, respectively. The population density of mosquitoes was determined using the human-bated net trap, while insecticide resistance was evaluated with the use of WHO larva immersion method. Results After the new countryside development, the relative population index of Cx. pipiens pallens in Xicun village was 0.285, with a 71.50% decrease. The resistance to propoxur, DDVP, and acetofenate decreased by 88.52%, 93.50%, and 87.67%, respectively, while the resistance to cypermethrin and deltamethrin increased by 30.15% and 34.38%, respectively. Conclusion The new countryside development showed a positive impact on the control of Cx. pipiens pallens in the lakeside area of Weishan Lake in Shandong province. The use of pyrethroids should be reduced in Xicun village of Hanzhuang town.
