Abstract

                                Mosquitoes nowadays are amongst the plagues of an English Summer. Except in two or three places, nothing is done to control them; and this is the more remarkable because so much is done with conspicuous success in other countries An account of what might be done in any of our towns or suburbs may be of interest. The first step is to obtain a systematic and scientific record of the different species of mosquito found in the locality, and of their breed- ing grounds. Of twentyfive species found in the United Kingdom, some are rare, and only seven are really im- portant from a "nuisance point of view". One breeds exclusively in holes in trees; another breeds in woodland pools, especially in pinewoods; another lays its eggs most freequently in water-barrels, tanks, and empty tins; another selects the shallow margins of weedy waters; another breeds in stagnant salt water; another in fresh, saltish or salt water; and the seventh breeds in swamps and ditches, and often in abominably foul water.
