ABSTRACT

Dispersal of mosquitoes is likely to be influenced by several extrinsic and intrinsic factors, including among others: meteorological conditions, local topography, physiological status of mosquitoes, body size, population density, and availability of oviposition and resting sites. Dispersal is commonly thought to result from flights made at random with air movement being important. Migratory flights may, however, be an integral part of the biology of the species. Dispersal can be measured by examining the decline in numbers of insects away from unique breeding sites. The most widely used method of determining mosquito dispersal is by capture-recapture experiments. Male mosquitoes, on the other hand, only need to discover a place to mate, a source of sugar and a place to rest. Because newly emerged females appear to disperse over a limited area, it would seem reasonable that males, too, should limit their dispersal to places where such females are likely to be found.
