Colonisation of the floodwater mosquito Aedes vexans (Meigen) (Diptera: Culicidae)

<p>A method of laboratory colonisation of several European and North American populations of Aedes vexans is described. A colony from the Rhine River Valley, near Maim, Germany, has been maintained in the laboratory for more than 150 cage generations. Another from the Queich River in the Rhine&nbsp;Valley of Southern Palatia, Germany has been maintained for 22 generations, and a colony from the&nbsp;Ticino River delta of Switzerland has been maintained for 12 generations. Six North American strains,&nbsp;one each from the states of Minnesota, Arizona, Oregon and Utah, and the Canadian Provinces of Manitoba and Ontario, are in cage generations 52, 20, 19, 14,41 and 15 respectively. Colonisation of&nbsp;different strains of this widespread pest mosquito opens up many research avenues.</p>
