The Age Structure of a Population of \u3ci\u3eAedes Provocans\u3c/i\u3e (Diptera: Culicidae) in Southwestern Ontario


In a previous paper it was shown that an eastern-Ontario population of the early-spring mosquito Aedes provocans had an atypical age structure: the adult-female population aged rapidly and synchronously, achieving an advanced gonotrophic age in an unusually brief period of time. The present study examined the age structure of Ae. provocans near Waterloo, in south-western Ontario, at a site at which adult emergence occurred over a wider, more variable period and at which the preferred nectar sources for young adults were much less abundant. In Waterloo, the adult-female population aged more slowly and much less synchronously than in eastern Ontario. The role of resources, particularly nectar, in leading to delayed aging, is discussed
