BACKGROUND   Southeast Brazil has recently experienced a Yellow Fever virus (YFV) outbreak where the mosquito  Haemagogus leucocelaenus  was a primary vector. Climatic factors influence the abundance of mosquito vectors and arbovirus transmission.    OBJECTIVES   We aimed at describing the population dynamics of  Hg. leucocelaenus  in a county touched by the recent YFV outbreak.    METHODS   Fortnightly egg collections with ovitraps were performed from November 2012 to February 2017 in a forest in Nova Iguaçu, Rio de Janeiro, Brazil. The effects of mean temperature and rainfall on the  Hg. leucocelaenus  population dynamics were explored.    FINDINGS    Hg. leucocelaenus  eggs were continuously collected throughout the study, with a peak in the warmer months (December-March). The climatic variables had a time-lagged effect and four weeks before sampling was the best predictor for the positivity of ovitraps and total number of eggs collected. The probability of finding > 50% positive ovitraps increased when the mean temperature was above 24ºC. The number of  Hg. leucocelaenus  eggs expressively increase when the mean temperature and accumulated precipitation surpassed 27ºC and 100 mm, respectively, although the effect of rainfall was less pronounced.    MAIN CONCLUSIONS   Monitoring population dynamics of  Hg. leucocelaenus  and climatic factors in YFV risk areas, especially mean temperature, may assist in developing climate-based surveillance procedures to timely strengthening prophylaxis and control.
