The aim was to survey the specific factors, which cause to decrease blood feeding of mosquitoes important to succeed vector control.
Larval collection was carried out from fixed and variable breeding places of Yazd County, central Iran in 2009. Autogeny-Anautogeny, Stenogamy-Eurygamy, and blood preference of Culex pipiens were studied using standard mosquito cages blood meal source for Cx. pipiens females considered as the chickens and human and fed females were kept in insectary condition (16:8 L: D, 27±3 °C and 70±10% RH). The data were analyzed using SPSS Ver. 11.5 soft ware.
Totally, 96 females' mosquitoes were tested for Stenogamy versus Eurygamy and 122 for blood preference assay. In the small cages (20 × 20 × 20cm) and large cage (60 × 40 × 60cm), the ability of mating and insemination rates were 60.0 and 67.0%, respectively. In spite of Cx. pipiens fed from sucrose 5%, none of them laying eggs in 60 × 40 × 60 cages during the study. This finding indicated the Anautogeny behavior of this species. This species was found of low tendency to human blood and almost 4 fold fed on chicken.
The occurrence of Steno-Eurygamy, Anautogeny, and Ornithophilic behaviors of Cx. Pipiens was noted. More studies need to be carried out about the bionomics of this species to gain more data about the ecophysiological and behavioral characteristics in other parts of Iran.
目的是调查导致对成功进行病媒控制至关重要的蚊子吸血减少的具体因素。
2009年从伊朗中部亚兹德县的固定和可变繁殖地采集幼虫。使用标准蚊笼对尖音库蚊的自体生殖-非自体生殖、狭交-广交及血液偏好进行研究，将鸡和人类作为尖音库蚊雌蚊的血餐来源，喂食后的雌蚊饲养在昆虫饲养条件下（16:8光:暗，27±3°C和70±10%相对湿度）。数据使用SPSS 11.5版软件进行分析。
总共对96只雌蚊进行了狭交与广交测试，对122只进行了血液偏好测定。在小笼（20×20×20厘米）和大笼（60×40×60厘米）中，交配能力和受精率分别为60.0%和67.0%。尽管尖音库蚊以5%的蔗糖为食，但在研究期间，它们在60×40×60厘米的笼子里均未产卵。这一发现表明该物种具有非自体生殖行为。该物种对人类血液的倾向较低，几乎4倍地以鸡为食。
注意到尖音库蚊存在狭交-广交、非自体生殖和嗜鸟行为。需要对该物种的生物学特性进行更多研究，以获取有关伊朗其他地区生态生理和行为特征的更多数据。
