32 THE MOSQUITOES OF NEW JERSEY 



The mosquito-catching ability of the 1933 type is at least as great 

 and perhaps greater than the 1932 type. No extensive changes have 

 been made in this 1933 type, which has come into general use. 



In 1932 traps were set along the Delaware Bay and Atlantic coasts 

 and throughout the metropolitan district of northeastern New Jersey 

 and have been continued each summer since that time. 



Each day's catch is boxed, sent to the laboratory, identified and re- 

 corded. A sample of the daily record sheets appears as Fig. XI. 



Since there are more than thirty traps in simultaneous operation 

 each season and each trap runs for about ninety days, to save space 

 only the total catches of each trap for the ten-year period beginning 

 in 1932 and ending in 1941 are given in Table I.
