INTRODUCTION 



SINCE THE MosauiTO WORK of the Ncw Jersey Agricultural Experi- 

 ment Station was begun by Dr. John B. Smith in 1900, three sub- 

 stantial mosquito publications of a general nature have been published 

 by the station. The first, issued in 1904, was Dr. Smith's monumental 

 report on mosquitoes occurring within New Jersey, their habits, life 

 history, etc. Since then the station has issued Bulletin 276 in 1915 and 

 Bulletin 348 in 1921, supplementing the information in Dr. Smith's 

 report. These were primarily for the use of practical mosquito control 

 workers. They are out of print, and the needs of mosquito control work 

 in this state demand that a new and up-to-date publication be issued. 



There is included in this book such information about mosquitoes, 

 their description, life histories, breeding places, food, natural enemies, 

 and control as to furnish scientific investigator and practical mosquito 

 worker alike with fundamental information, necessary to a proper un- 

 derstanding of mosquitoes and their control. While the subject matter 

 of this publication is primarily scientific, it is intended to be of value 

 not only to teacher, student, and those engaged in practical mosquito 

 work, but to the lay reader as well. 



The publication of this book was made possible by the cooperation of 

 the New Jersey Mosquito Extermination Association, the several county 

 mosquito extermination commissions, and the New Jersey Agricultural 

 Experiment Station. My sincere appreciation is herewith expressed to 

 the members and executives of the county mosquito commissions, to the 

 staff of the Entomology Department of the New Jersey Agricultural 

 Experiment Station, to my associates in other departments, and to 

 all others who have assisted in collecting and preparing subject matter, 

 checking manuscript, and reading proof. 



Acknowledgment is hereby given to Howard, Dyar, and Knab, whose 

 publication Mosquitoes of North and Central America and the West 

 Indies, has furnished descriptions of several species of mosquitoes 

 needed to complete the chapter on Mosquito Biology. Practically the 

 entire chapter on Mosquito Biology was taken directly from Dr. Smith's
