Diel Patterns of Mosquito Activity in a High Arctic Locality: Hazen Camp, Ellesmere Island, N.W.T.
Abstract Diel patterns of emergence, flight, host-seeking and oviposition have been studied in two mosquitoes, Aedes ( Ochlerotatus ) impiger and A . (O.) nigripes , at Hazen Camp (71° 18′ W., 81° 49′ N.). Diel periodicities were detected in both species for all these activities except flight. Ovipo...

| Summary: | Abstract Diel patterns of emergence, flight, host-seeking and oviposition have been studied in two mosquitoes, Aedes ( Ochlerotatus ) impiger and A . (O.) nigripes , at Hazen Camp (71° 18′ W., 81° 49′ N.). Diel periodicities were detected in both species for all these activities except flight. Oviposition of A . nigripes shows a well-defined pattern, but otherwise periodicities are evident only as slight and somewhat irregular diel fluctuations. All diel patterns show a maximum near solar noon, and appear to result from a direct (exogenous) response to ambient temperature. The patterns of host-seeking flight, closely similar in both species, are compared with those recorded for Aedes ( Ochlerotatus ) at lower latitudes. Small morning and afternoon peaks at Hazen Camp are seen as vestiges of sunrise and sunset maxima that characterize this periodicity further south. |
