[Environmental conditions of evening activity of synanthropic mosquito species (Diptera: Culicinae) in the Wroclaw area]. / Srodowiskowe uwarunkowania wieczornej aktywnsci synantropijnych gatunków komarów (Diptera: Culicinae) na terenie Wroclawia.

ABSTRACT

MATERIALS AND METHODS: Temporal variations in the evening activity pattern of adult mosquito females of locally common mosquito were studied at Wroclaw area using CO2 charged olfactory traps. RESULTS: There has been 4856 synanthropic individuals which belonged to Culex pipiens (L.) i Culiseta annulata (Schrank.) species distinguished from the general population of 5997 individuals caught in the three sampling sites. The number of active mosquito females increased from 4 pm to 9 pm creating one distinct peak during the evening activity maximum. Statistical analysis of the results showed the important correlation between mosquito activity of locally common populations and air relative humidity supported by variation of light intensity.
