6 THE MOSQUITOES OF NEW JERSEY 



quitoes, undoubtedly salt marsh species, were extremely and seriously 

 troublesome throughout the entire coastal area of the Atlantic Ocean 

 and Delaware Bay. 



Although a considerable amount of anti-mosquito work had been 

 done in the Newark Bay marshes prior to 1913 the writer saw a tre- 

 mendous brood from the Newark Bay marshes about July 15, 1913 

 sweep over the adjacent upland, reaching as far north as Morristown 

 and north of Paterson. Again in 1914* the same thing occurred about 

 the same time of year and simply blanketed with mosquitoes the entire 

 area from the marshes to and across the first range or two of moun- 

 tains. He recalls one early evening at the Market Street Station in 

 Newark where the station was so filled with mosquitoes that passengers 

 were everywhere slapping and salt marsh mosquitoes could be seen rest- 

 ing in large numbers on the inside walls of the station. There were many 

 instances in the early years when mosquitoes came into Newark and 

 Jersey City and penetrated the stores in such numbers that they had to 

 be swept out of the show windows after they died. 



Evidently the mosquitoes in northern New Jersey, particularly in 

 Newark, were originally as abundant and troublesome as they are now 

 known to be in certain areas of the Bay Coast. In fact, the location of 

 the Newark Bay salt marshes with regard to prevailing winds should 

 give Newark about as great a supply of mosquitoes before any work 

 was done against them as Cedarville originally got from certain 

 marshes of the Delaware Bay. 



Out of the total catch of 183,096 A'edes sollicitans in thirty-five 

 traps, for five successive years from 1932 to 1936 inclusive, 97,964, or 

 a little more than half of the total, were taken in a single trap located 

 at Cedarville in Cumberland County. The traps were located at two 

 points in Sussex County, one in Morris, two in Passaic, three in Bergen, 

 four in Hudson, four in Essex, two in Union, four in Middlesex, two in 

 Monmouth, five in Ocean, four in Atlantic, four in Cape May, one in 

 Cumberland, and one in Salem. 



If we may assume that originally the infestation in and about Newark 

 was as bad as it has been until the end of 1936 about Cedarville and that 

 the largest catch in that area in the five years above mentioned was 

 1,078, the reduction due to anti-mosquito work in the Newark area runs 

 about 98,9 per cent. The great salt marsh broods that used to rise from 

 the Newark Bay, Hackensack, and Staten Island marshes and blanket 

 the entire area between the marshes and the mountains to the northwest, 

 north and northeast have disappeared and this disappearance must be 

 ascribed to anti-mosquito work.
