PREFACE 



Along with the marked increase in public appreciation of 

 preventive medicine, that has developed in recent years in the 

 United States, has come a recognition of the great importance 

 of mosquito eradication, particularly in the South. This has 

 manifested itself in the launching of anti-mosquito campaigns in 

 cities, towns and villages in every Southern State, and it is a 

 foregone conclusion that the success of these will spur other 

 communities on to action. 



Abroad, too, the menace of the mosquito-borne diseases is 

 being recognized. In the tropical and sub-tropical areas of 

 Latin-America, the International Health Board of the Rockefeller 

 Foundation has done, and is doing, very valuable work. Many 

 American corporations employing labor in those regions have 

 found that it pays to protect their labor, and are doing so. 

 Furthermore, the governments of many of the Latin-American 

 countries are awakening to the heavy toll of the mosquito- 

 borne diseases, and are taking steps to eradicate them. 



The same may be said of many regions in Europe, Asia and 

 Africa. Anti-mosquito work now is being carried on to a greater 

 or lesser extent in Italy, Spain and several of the Balkan coun- 

 tries; in Mesopotamia, India, Ceylon, the Malay Peninsula and 

 many Pacific islands; in East and West Africa, Madagascar and 

 various other political subdivisions. 



This means that, in the aggregate, an enormous volume of 

 anti-mosquito work is being done today. And, as the fruits of 

 this work become better known and appreciated, it will increase 

 many fold in all the above-mentioned countries. Furthermore, 

 as other territories, that are today undeveloped, awake, more 

 anti-mosquito work will have to be done, if man is to exploit 

 their resources efficiently. 



This vast volume of work, both present and prospective, 

 renders it incumbent that only the best methods should be 

 employed. While many persons may have a general idea as to 

 the procedure in mosquito eradication, this is not sufficient for the
