The systematics of the Culex pipiens complex.

摘要: It was concluded in 1951 that the Culex pipiens complex could best be treated as a single polytypic species. Since then observations on morphologically and biologically intermediate forms have strengthened this conclusion. These are supported by results of experimental work temperature tolerances, winter diapause mating behaviour crossing experiments. Discussions possible role cytoplasmic isolating factors initiating speciation within not been sufficiently conclusive. The relative fitness hybrids may more important determining their rarity or otherwise particular populations than rather tenuous barriers so far demonstrated. two further forms-C. p. australicus C. globocoxitus-have added to complex, there is evidence extensive replacement torrentium England. therefore unwise neglect dynamic aspects geography complex. A comprehensive review morphological badly needed.
