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: The experiment was designed to determine the degree Stenogamy or Eurygamy behaviors in a 60 × 40 × 60cm (Fig. 2A), and 20 × 20 × 20cm (Fig. 2B) cages. The spermathecae of the females Cx. pipiens were dissected for evidence of insemination (Fig. 3). The larvae were reared in insectarium and pupae were separated and transferred into cups inside the cages. Autogeny, Anautogeny and blood preference of this species also were studied with rearing the larvae and transferred the pupae in cages. Sucrose 5% and moisture cotton wool were used for feeding of this species in each cage. Petri dishes with no chlorine water were used for oviposition. Eurygamy, and Stenogamy behaviors were studied 10 days after emerging and mating of species using the dissection of spermathecae. Anautogeny and Autogeny behaviors of non blood feeding mosquitoes were studied at a 16:8 L: D, 27±3 °C and 70±10% RH for 20 days. Adult females were fed on chickens and human forearm for blood meal source in insectary. Fifty eight female mosquitoes were used for feeding on chicken and sixty four for human blood type. (Knight and Malek 1951, WHO 1975, Vinogradova 2000). The data were analyzed using SPSS Ver. 11.5 soft ware.
