Population dynamics of Chaoborus punctipennis Say (diptera: chaoboridae) in a new southeastern cooling reservoir

A population study of Chaoborus punctipennis (Say) in L Lake, a new southeastern cooling reservoir, was conducted from January 1986 to December 1989. This investigation was part of a larger, and still ongoing, environmental impact study on this impoundment. Relatively few data for any southeastern Chaoborus population have been published in the open literature, especially long-term data sets. The objectives of our study were to document the life history of C. punctipennis in L Lake and provide estimates of annual standing stock density/biomass and emergence rates
