The characteristics of a larval habitat is an important factor which affects the breeding pattern and population growth of mosquitoes Information about the larval habitat characteristics and pupal productivity can be utilized for the surveillance of the level of population growth, species diversity, and preferred breeding sites of mosquitoes, which are important aspects of integrated vector control. In the present study, mosquito larvae were collected from 22 natural habitats in five counties of the West Azerbaijan Province in the Northwest of Iran during May–November 2018. Physicochemical characteristics of the habitats were investigated. These included alkalinity, chloride (Cl) content, water temperature (°C), turbidity (NTU), Total Dissolved Solids (TDS) (ppm), Electrical Conductivity (EC) (μS/cm), and acidity (pH). The index of affinity between the collected species was calculated using Fager & McGowan test. A total of 2715 specimens were collected and identified. Seven different species belonging to four genera were identified in our study sites. The species included, Culex pipiens Linnaeus 1758, Culex theileri Theobald 1903, Culex mimeticus Noé 1899, Culex modestus Ficalbi 1947, Culiseta longiareolata Macquart 1838, Anopheles maculipennis Meigen 1818complex, and Aedes caspius Pallas 1771. There was a significant difference in chloride content and water temperature preferences among the different species (P < 0.05). Also, there was no significant difference in pH, Alkalinity, Turbidity, TDS, and EC preferences among the different species (P > 0.05). The affinity between the pair of species Cx. mimeticus/Cs. longiareolata was 0.526. There was no affinity between other pairs of species or the affinity was very weak. The physicochemical and biological characteristics of mosquito larval habitats play an important role in zoning of areas suitable for breeding and distribution. Surveillance of these characteristics can provide valuable information for entomological monitoring of mosquito vectors and for designing targeted control programs. Also, further studies should be undertaken in a wider geographical area, taking into account the complex characteristics of the physicochemical and ecological factors of the study area and their interaction with various mosquito species.

伊朗西北阿塞拜疆省的幼虫栖息地和蚊子物种多样性

幼虫栖息地的特性是影响蚊子繁殖方式和种群增长的重要因素，有关幼虫栖息地特性和p生产力的信息可用于监测种群的生长水平，物种多样性和首选的繁殖地点。蚊子，这是集成矢量控制的重要方面。在本研究中，于2018年5月至11月从伊朗西北阿塞拜疆省五个县的22个自然栖息地收集了蚊虫幼虫。调查了这些栖息地的理化特性。其中包括碱度，氯化物（Cl）含量，水温（°C），浊度（NTU），总溶解固体（TDS）（ppm），电导率（EC）（μS/ cm）和酸度（pH）。使用Fager＆McGowan检验计算收集的物种之间的亲和力指数。总共收集并鉴定了2715个标本。在我们的研究地点确定了属于四个属的七个不同物种。该物种包括：淡色库蚊（Culex pipiens Linnaeus）1758，库勒斯泰勒（Thelexri Theobald）1903，拟似库蚊（Culex mimeticusNoé）1899，库克斯模式Ficalbi（Ficalbi）1947，长库蚊（Culiseta longiareolata Macquart）1838，按蚊按蚊Meigen 1818复合体和白纹伊蚊（Aedes caspius Pallas）1771。氯化物含量存在显着差异。不同物种间的温度偏好（P <0.05）。而且，不同物种之间的pH，碱度，浊度，TDS和EC偏好也没有显着差异（P> 0.05）。这对物种Cx之间的亲和力。模拟/ Cs。longiareolata为0.526。其他物种对之间没有亲和力，或者亲和力很弱。蚊虫幼虫栖息地的理化和生物学特性在适合繁殖和分布区域的分区中起着重要作用。对这些特征的监视可以为蚊媒的昆虫学监测和设计目标控制程序提供有价值的信息。此外，应考虑到研究区域理化和生态因素的复杂特征及其与各种蚊虫的相互作用，在更广阔的地理区域内进行进一步的研究。蚊虫幼虫栖息地的理化和生物学特性在适合繁殖和分布区域的分区中起着重要作用。对这些特征的监视可以为蚊媒的昆虫学监测和设计目标控制程序提供有价值的信息。此外，应考虑到研究区域理化和生态因素的复杂特征及其与各种蚊虫的相互作用，在更广阔的地理区域内进行进一步的研究。蚊虫幼虫栖息地的理化和生物学特性在适合繁殖和分布区域的分区中起着重要作用。对这些特征的监视可以为蚊媒的昆虫学监测和设计目标控制程序提供有价值的信息。此外，应考虑到研究区域理化和生态因素的复杂特征及其与各种蚊虫的相互作用，在更广阔的地理区域内进行进一步的研究。
