JAPANESE FLOWER BEETLE 



By W. H. GooDW'iN 



Some ten miles northeast of Camden, and a few miles back from the 

 Delaware River opposite Tacony, North Philadelphia, is the location 

 where the Japanese flower beetle has become established, temporarily 

 at least. The infested territory lies between Moorestown and River- 

 ton, N. J., and at present covers some four or five thousand acres of 

 very productive sandy loam farms. The country is gently rolling and 

 the greatest altitude is not over one hundred feet above sea leveh It 

 is drained by small creeks but the entire area lies between the two larger 

 streams, Pensauken and Rancocas creeks. Farming in this district 

 is intensive ; the principal crops, excepting for a small amount of general 

 farm crops, are such truck crops as tomatoes, sweet corn, asparagus, 

 peas, and beans, which find a ready market in the city. Peaches, apples, 

 pears, and cherries do well in this locality and are quite extensively 

 grown. 



The soil varies greatly in texture and general mechanical composi- 

 tion, varying from a rather stiff heavy clay soil to almost pure sand. 

 Sometimes these extremes in soil variation occur within the compara- 

 tively short distance of only a few rods. 



These principal soils are known as Sassafras, Freneau, and Elkton 

 loams with a few small areas of other types. 



The people are largely Quakers and, I take it, are descendents of the 

 early settlers of this district. 



In April, 1918, final action was taken to begin active steps for the 

 eradication of this newly acclimated pest, for pest it is, as the meager
