    Author: Hong SC, Lv Y, Fang FJ, Zhu CL.
    Journal: Zhongguo Xue Xi Chong Bing Fang Zhi Za Zhi; 2014 Dec; 26(6):672-4, 680. PubMed ID: 25856898.
    Abstract:
    OBJECTIVE: To investigate the relationship between Wolbachia and deltamethrin resistance in Culex pipiens pallens. METHODS: PCR was used to detect Wolbachia in Culex pipiens pallens and qRT-PCR was performed to determine and compare the expression of Wolbachia between deltamethrin- resistant and - susceptible strains of Culex pipiens pallens. RESULTS: Wolbachia was detected in Culex pipiens pallens in the laboratory. The expression of Wolbachia was 18.42, 3.69, 4.43, 3.96, 6.31, 1.55 and 3.76 folds higher in the deltamethrin-resistant strain than in susceptible strain in the egg, 1st, 2nd, 3rd, 4th stages, and male and female adults, but there was no statistical difference in the pupae stage. The expression of Wolbachia was 2.64 folds higher in deltamethrin-resistant females than in susceptible females which were caught in Jiangxinzhou of Nanjing. CONCLUSION: Wolbachia is associated with deltamethrin resistance in Culex pipines pallens.
