INTRODUCTION 



The Japanese beetle is a serious pest of apples, peaches, plums, 

 cherries, and small fruits and also causes considerable injury to certain 

 ornamental shade trees and shrubs in the eastern part of the United 

 States. This brilliantly colored, green and reddish-bronze beetle 

 feeds on the foliage, blooms, and fruit. 



This circular gives the latest recommendations for the control of 

 the beetle on different fruits and ornamental plants. The recom- 

 mendations given are intended to apply only to the generally infested 

 area. In those areas where the infestation is so light that no appre- 

 ciable injury is caused, there will be little need for the adoption of 

 control measures. 



DISTRIBUTION OF THE BEETLE 



The Japanese beetle is a native of Japan. It was first discovered 

 in the United States in Burlington County, N.J., in the summer of 

 1916. The area of continuous infestation wherein general injury 

 may occur comprises southern and central New Jersey, eastern 

 Pennsylvania, northern Delaware, and the District of Columbia. 

 Similar injury is also found locally in parts of Maryland. The beetle 

 has also been found at several points in New England, New York, 

 Ohio, Michigan, Virginia, West Virginia, North Carolina, and South 

 Carolina, but those captured in the more southern and western of 

 these States may have been carried there by train or otherwise a short 

 time before discovery and may thus not represent established in- 

 festations.
