Highly polluted larval habitats of the Culex pipiens complex in central Sweden.
Larvae of the Culex pipiens complex (Cx. pipiens and Cx. torrentium) were abundant in two highly polluted pools receiving sewage sludge in Uppsala, Sweden (early August through late September 1985). The water was characterized by high BOD, and high ion concentration of Cu, Fe, Al and much suspended matter. Maximum larval number at the pool surface area was 26.1/ml. The ratio between species was studied and Cx. torrentium comprised ca. 20% at the peak of abundance. Some egg rafts showed no embryogeny.
