[1st isolation of Aedes (Ochlerotatus) sticticus (Diptera, Culicidae) in the Po-Venetian valley].

Aedes sticticus is recorded for the first time in northern Italy. The species was collected in some relict woods mainly at sea level in the Po-Venetian valley (Northern-Italy). Larval growth took place in residual puddles originated by rain or river floods. The most abundant adult emergence was observed in April or May. Minor earlier or later adult emergencies were observed depending from egg submersion and temperature. Data on larval chetotaxy are presented.
