Dehghan H, Moosa-Kazemi SH, Sadraei J, Soleimani H - J Arthropod Borne Dis (2013)

Bottom Line: This species was found of low tendency to human blood and almost 4 fold fed on chicken.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.

ABSTRACT

Background: The aim was to survey the specific factors, which cause to decrease blood feeding of mosquitoes important to succeed vector control.

Methods: 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.

Results: 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.

Conclusion: 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.

Mentions: A descriptive cross sectional study was carried out in Yazd County, Central Iran in summer 2009. The study took place in two randomly selected rural villages with 889 houses and 24358 populations in Yazd County (54°04′N 31°59′E). The study area is located in the Yazd Province and bounded by Isfahan in the west, South Khorasan in the east, Kerman and Fars in the south, Khorasan-e-Razavi and Seman Provinces in the north (Fig. 1). The maximum and minimum mean monthly temperatures were recorded as 40.6 °C in July and −4.4 °C in January In 2009. The total annual rainfall was 62 mm, the minimum of 0.3 mm in May and maximum of 18 mm in March. The mean annual relative humidity was 37%. The main occupation of the peoples is agriculture and husbandry of cow and goats. Based on available epidemiological data from Yazd Health Centre, there are no villages under the entomological survey.
