Habitat selection strategies of mosquitoes inhabiting citrus irrigation furrows.
The mosquitoes Aedes vexans, Psorophora columbiae and Psorophora howardii have recently extended their habitat distribution into citrus irrigation furrows in coastal southeastern Florida. Oviposition site selection was examined by correlating species abundances with water depths due to rainfall or flood irrigation. Psorophora columbiae and Ps. howardii oviposited low in furrows, shared similar distributional relationships to water depths and were hatched by rainfall or irrigation. Aedes vexans oviposted higher in the citrus furrow, showed a different relationship to water depth and were hatched only by flood irrigation.
