Mosquito Extermination in the State of New York. — U.S. Public Health 

 Repts., Washington, B.C., xxxi, no. 41, 13th October 1916, 

 pp. 2910-2919. 



In a new article added to chapter 49 of the laws of 1909, dealing 

 with mosquito extermination in the State of New York, provision is 

 made for the appointment of County Commissions, who shall use every 

 means feasible and practicable to exterminate mosquitos of every 

 variety found within the county for which such Commission is 

 appointed. Any accumulation of water in which mosquitos are 

 breeding, or are likely to breed, is declared a nuisance. Members are 

 to serve unpaid, though actual expenses in connection with the meetings 

 are allowed for. 



Zetek (J.). Reducing Malaria by reducing the Number of Anopheles 

 within Buildings.— ^ww. Entom. Soc. America, Columbus, Ohio, 

 ix, no. 3, September 1916, pp. 275-283, 1 fig., 2 charts. [Received 

 4th November 1916.] 



The observations recorded in this paper were made during 1912 at 

 Mira Flores construction camp. Canal Zone. Five possible extensive 

 breeding places of Anopheles were found in the vicinity. The pre- 

 dominant species was A. alhimanus, Wied. ; A. pseudopunctipennis, 

 Theo., was present in smaU numbers during the dry season, and a few 

 specimens of A. apicimacula, D. & K., A. argyrotarsis, R.-D., and 

 A. malefactor, D. & K., were captured. 



Two camps are compared to illustrate the effect of external traps on 

 the number of mosquitos entering them. In one provided with four 

 traps, the number of mosquitos captured inside was 33 per cent, of the 

 total for the two camps ; in the other which was further away from 

 the breeding ground and was without traps, the number was 67 per 

 cent of the total. The second camp further showed a much higher 

 malarial rate than the first. 



This method of reducing the numbers of mosquitos by trapping is 

 applicable to other temporary camps in malarious regions and,
