Introduction: With regard to probable malaria epidemy and mosquito (Diptera: Culicidae) biting nuisance during their seasonal activity in Guilan province (North of h-an, Caspian littoral), and to studʹ mosquito fauna and ecology, an investigation was carried out during April to December 2000 in the province.
Methods: In 41 occasions, 1506 adult mosquitoes, resting or blood sucking, were collected , fi-om 64 habitats including: inner places like house, stable, hen shelter and wash closet and natural outer places including vegetation, tree hole, rock hole and artificial outer places like open well and discarded tire by means of aspirator and captorator. Wall surface material of resting-places were recorded for each inner places including wood, plaster, mud and cement. Also, a few occasions of collecting were carried out by means of CDC light trap.
Results: In this study, 14 species, as adult, were totally collected as follow: An. claviger, An. hyrcanus, An.maculipennis s.l., An.pseudopictus, Ae.vexans, Cq.richiardii, Cx.hortensis, Cx.mimeticus, Cx.pipiens, Cx.theileri, Cx.tritaeniorhynchus, Cs.annulata, Oc.caspius s.l. and Oc.geniculatus.
As a whole, 66.4% specimens were collected from inner places and 33.6% ones from outer places and
92.9% and 7.1%.for the genus Anophele and 43.93% and 56.07% for. the subfamily culicinae from inner
places and outer places, respectively. Cx.hortensis, Cs.annulata and Oc.caspius s.l. were only collected from inner places, the two first species from stable and the third one. from human house, with very little frequency.
outer places with very little Also, An.claviger, Cq.richiardii and Oc.geniculatus were only collected. from frequency.
Conclusion: According to this study, stables are the most important inner places of malaria vectors for cresting and blood sucking from their primary hosts, cows, in Guilan province. It is noteworthy during residual spraying.
