background: there are unorganized, published documents about the ecology of mosquitoes (diptera: culicidae) in northeastern part of iran. the purpose of this study was to determine the distribution and characteristics of larval habitats of culicidae in kalaleh county. methods: larvae were collected using dipping method and adults by human landing catch technique during april–october, 2012. larv...
وضعیت تاکسونومیک culex pipiens از سال ها پیش به عنوان گونه ای با تنوع وسیع از نظر مورفولوژیک و بیولوژیک به خوبی شناخته شده بود؛ به طوری که این تغییرات موضوع تحقیقات گسترده ای توسط بسیاری از محققان شده است. بر این اساس مطالعه کمپلکس cx. pipiens با توجه به تفاوت در اقلیم های زیستی اعضای آن، همچنین توزیع آنها که با پراکندگی جغرافیایی انسان ها همپوشانی دارد، به نظر می رسد در کشور ما به عنوان مطالعه...
Mosquitoes within the Culex pipiens complex have been implicated as major vectors of West Nile virus (WNV) in North America due to their seasonal abundance, vector competence and high field infection rates. However, the role of Cx. p. pipiens complex mosquitoes in enzootic amplification of WNV among avian hosts and epidemic transmission to humans varies throughout its geographical distribution....
Mosquitoes in the Culex pipiens complex (Diptera: Culicidae), especially Cx. pipiens and Culex quinquefasciatus, have successfully exploited the rapid growth of the human population and globalization to their advantage by successfully utilizing man-made habitats, particularly for oviposition. Culex spp. lay over 100 eggs together in a raft. Each egg in the raft produces an apical droplet contai...
The medically important members of the Culex pipiens species complex provide an enigma for systematists, evolutionary biologists, and vector biologists. The species complex is composed of forms that differ in their ecology, behaviour, physiology and vector competence. Cytoplasmic incompatibility (CI) caused by endosymbiotic Wolbachia bacteria is thought to play an important role in restricting ...
Mosquitoes in the Culex pipiens complex are considered to be involved in the transmission of a range of pathogens, including West Nile virus (WNV). Although its taxonomic status is still debated, the complex includes species, both globally distributed or with a more limited distribution, morphologically similar and characterised by different physiological and behavioural traits, which affect th...
Females of Culex pipiens pallens are rarely inseminated at temperatures above 30 degrees C. Insemination and egg-hatching rates (F2) were examined in females of hybrids (F1) between Culex pipiens pipiens and Culex pipiens quinquefasciatus at 25 degrees C and 30 degrees C to examine temperature-dependent reproductive activity. Insemination rates were very high in hybrid females (F1) at 25 degree...
