The control of the mosquito nuisance in our most important National 

 Parks which are visited by tens or hundreds of thousands of people each 

 year will appeal to most tourists and to many others who remain at 

 home. When the writer visited the Yellowstone National Park fifteen 

 years ago this summer, mosquitoes were rather annoying around some 

 of the permanent camps, and when asked to speak at one of the open 

 fireside gatherings in the evening at one of these camps, he explained 

 the biology and habits of mosquitoes and predicted the future control 

 of this nuisance by Governmental agencies. As these species are local, 

 it would not be so difficult a problem as it may seem to the uninitiated, 

 to do away with most of the nuisance around the permanent camps and 

 hotels and around the areas where public camping is permitted. Possiby 

 some system of control is already in force, but if so the writer has not 

 heard of it. It is gratifying to learn that the Canadian Government 

 has already undertaken to control the mosquito pest in Rocky Mountain 

 National Park as will be seen by another note in this issue. It is also 

 gratifying to learn that these efforts are already bearing fruit, and that 

 the spring work has greatly reduced the numbers of adult mosquitoes. 

 A temporary laboratory has been established at Banff, and the Ento- 

 mological Branch and the Park officials are working in close co-operation. 



Our National Parks are considered a national asset. Some of them are 

 not visited by tourists and may well be left in their natural condition. 

 Other parks are maintained for tourists and in them the health and com- 

 fort of the visitors should be safeguarded. It is hoped that mosquito 

 control may soon be inaugurated in other National Parks both in Canada 

 and in the United States.
