§ Sir W. DAVISONasked the Minister of Health whether his attention has been called to the continued increase in the number of mosquitoes in this country; and what action is being taken to combat this menace to the national health?
§ Miss LAWRENCEMy right hon. Friend is advised that the number of mosquitoes in this country fluctuates from year to year according to the climatic conditions, but does not show any general increase. In the present year some species (especially the sylvan species) are unusually prevalent. My Department, in collaboration with the British Museum (Natural History), has given attention to this matter for some years past, and a pamphlet on "British Mosquitoes and their Control" has been published which contains advice on the best methods of combating mosquito pests. My Department is also prepared on request to advise local authorities on the matter.
