Mosquitoes are the most important vectors of serious infectious diseases in the world. Dengue, Zika, chikungunya and yellow fever are emerging and re-emerging infectious diseases, associated with the distribution of two key vectors i.e.Aedes aegyptiandAedes albopictusthroughout the world including countries neighbouring Iran. Entomological surveillance was planned and performed monthly from May to December during 2014–2020 in selected counties of Mazandaran Province, North of Iran, by ovitrap, larval collection, hand catch and human baited trap. Overall, 4410Aedesspecimens including 2376 larvae (53.9%) and 2034 (46.1%) adults belonging to six species, namelyAedes vexans, Aedes geniculatus, Aedes caspius, Aedes echinus, Aedes pulcritarsisandAedes flavescencewere collected and morphologically identified. Over the seven years of surveillance,Ae. aegyptiandAe. albopictuswere not found by any sampling method.Aedes vexansandAe.geniculatuswere the most abundant species, their populations peaked in October and November and was positively correlated with precipitation and relative humidity.Aedes flavescencewas a new species record for the province. A flowchart for planning and implementation of invasive mosquito surveillance for provincial health authorities in the country is proposed. These surveillance efforts provide basic and timely information for the health system to act promptly on integrated and intensified surveillance and control programs shouldAe. aegyptiandAe. albopictusdetected in the province.
