2IO N. J. Agricultural Experiment Station, Bulletin 348 



* Summary 



At the present time there are three legaHzed agencies for mosquito 

 suppression. The local and state boards of health operating under 

 the authority of the Duffield Act, the State Agricultural Experiment 

 Station operating under authority of Chapter 134, Laws of 1906, 

 and devoting its attention primarily to the supression of the salt- 

 marsh mosquitoes but also supplying technical assistance to the 

 boards of health and other organizations ; the county mosquito ex- 

 termination commissions, operating under the authority of Chapter 

 104, Laws of 1912, as amended by Chapter 288, Laws of 191 5, and 

 Chapter 123, Laws of 1919, and devoting its attention to the mos- 

 quito problem as a whole. 



The work of the three organizations is unified by the following 

 facts: (i) that the law enforcement officer, director of the New 

 Jersey State Agricultural Experiment Station designated in Chapter 

 134, Laws of 1906, is ex-officio a member of all county mosquito 

 commissions and responsible for the nature of the plans, methods 

 and estimates used by them; (2) that this same officer finds it his 

 duty to see that proper technical assistance is furnished to boards 

 of health in their mosquito campaigns; (3) that the director of the 

 State Department of Health is ex-officio a member of all county 

 mosquito commissions and thereby keeps in touch with their activi- 

 ties. 



An organiation known as the New Jersey Mosquito Extermination 

 Association has been created in which all anti-mosquito interests can 

 be gotten together and from which the general policies relative to the 

 solution of the jjroblem, can be and are promulgated. 



A Brief Analysis of the New Jersey Mosquito Problem 

 Geographical and Biological Conditions 



The first phase of the problem of mosquito control in New Jer- 

 sey is the elimination of the breeding of the salt-marsh forms. The 

 second phase is the elimination of the breeding of the fresh-water 

 forms. 



From the standpoint of mosquito control the area of the state 

 naturally falls into two main divisions. The first includes the coast- 

 al edge extending from thirty to forty miles back from the coast- 

 line. The second includes all territory of the state surface back of 

 this coastal zone. In the coastal zone the preeminent mosquito prob- 

 lem is the salt-marsh one; but there is a secondary problem which
