After overcoming the significant obstacle of getting adult Culex mosquitoes to reproduce and blood feed in the laboratory, maintaining a laboratory colony is much more achievable. However, great care and attention to detail are still required to ensure that the larvae have adequate food without being overwhelmed by bacterial growth. Additionally, achieving the appropriate densities of larvae and pupae is essential, as overcrowding delays development, prevents pupae from successfully emerging as adults, and/or reduces adult fecundity and alters sex ratios. Finally, adult mosquitoes should have constant access to H2O and nearly constant access to sugar sources to ensure that both males and females have adequate nutrition and can produce the maximum number of offspring. Here, we describe our methods for maintaining the Buckeye strain of Culex pipiens and how other researchers might modify them to suit their specific needs.
