Abstract

The midgut bacterial flora of wild-caught , and mosquitoes was investigated. Dissected midgut contents were examined using quantitative aerobic bacterial cultures. Individual colonies (n = 134) were subcultured and identified to species. Midgut bacterial counts changed dramatically during mosquito development. A 280–1,100-fold decrease in the bacterial population occurred between the larval stage and pupal emergence, whereas a subsequent 70–16,000-fold increase occurred after blood-feeding. Bacterial identifications revealed a complex flora with up to nine genera identified during any stage of development. Species most frequently isolated were , and . The presence of genetically well-characterized bacteria in the midgut flora of mosquitoes may provide a means of expressing novel genetic products in vector species.
