Extract

Animal and plant enemies undoubtedly play an important part in controlling mosquitoes, but it is fully recognized that a study of these organisms forms only one phase of a very complex subject spoken of generally as natural control. Climate, weather conditions, topography, etc., all have an important bearing on mosquito abundance. Precipitation, whether in the form of rain or snow, and temperatures, exert a vital influence on mosquito populations. If the winter accumulation of snow is heavy, the spring infestation of snow pool and floodwater mosquitoes may be expected to be heavy too.
