Culex pipiens complex shows variations in morphological and biological characters including different biological forms and has medical and veterinary importance. Because of having morphological variations, sometimes it is not easy to separate this species from Cx. quinquefasciatus and Cx. torrentium. The aim of this study was to identify the Culex pipiens complex species in order to use in control programs in the future.
This study was carried out in two randomly selected rural villages in Yazd County, eastern Iran using dipping technique from April to October 2009. The data were analyzed using SPSS software version 16.
Average of siphon index in fourth-instrar larvae was 3.86±0.03, the minimum and maximum were calculated 2.43 and 5.14, respectively. Siphon/Saddle index was measured as average, minimum and maximum 3.2±0.2, 2.78, and 4.42 respectively. In our study, only 4 specimens had single seta 1 on segments III and VI (2.5%) and the remaining beard double seta (97.5%). The maximum 3-6 branches seta 1a-S and 1b-S (95%) were observed on siphon.
More populations of Culex pipiens from different areas of Iran need to be studied to gain complete information about the taxonomy and ecology of the species in the country.
致倦库蚊复合组在形态和生物学特征上存在变异，包括不同的生物型，具有医学和兽医学重要性。由于存在形态变异，有时很难将该物种与致倦库蚊和骚扰库蚊区分开来。本研究的目的是鉴定致倦库蚊复合组物种，以便未来用于防控计划。
2009年4月至10月，在伊朗东部亚兹德县随机选取的两个乡村，采用浸渍法开展本研究。数据使用SPSS 16.0软件进行分析。
四龄幼虫的虹吸指数平均值为3.86±0.03，最小值和最大值分别为2.43和5.14。虹吸/鞍状指数的平均值、最小值和最大值分别为3.2±0.2、2.78和4.42。在我们的研究中，只有4个标本在第III和VI节有单根刚毛1（2.5%），其余的有双根刚毛（97.5%）。在虹吸上观察到最多3 - 6分支的刚毛1a - S和1b - S（95%）。
需要对来自伊朗不同地区的更多致倦库蚊种群进行研究，以全面了解该国该物种的分类学和生态学信息。
