REPORT OF THE STATE ENTOMOLOGIST I917 5I 



following year are very destructive because it is then that most 

 of the growth occurs and consequently there is more feeding. The 

 abundance of the pests can be approximated by the amount of 

 feeding upon trees; attention w^as called to this last spring in an 

 effort to interest farmers in judging the probabilities for another 

 season. The grubs are so small at the end of the first summer or 

 in the following spring, being about one-fourth of an inch in length, 

 that they can be easily overlooked unless a special search is made. 

 They have the general characteristics of the larger ones and are 

 therefore easily recognized, and it is possible by careful examination 

 to determine whether there are any numbers in sod land. The 

 probabilities favor severe injury by white grubs to susceptible crops, 

 such as potatoes and corn planted on recently turned sod in the 

 vicinity of trees which were defoliated last year. Farmers are 

 advised to look into this matter carefully and if it is necessary to 

 plant such crops upon sod land, to make careful examination so 

 as to be certain that small white grubs are not sufficiently numerous 

 as practically to prevent the securing of a crop. It would be safer 

 in sections where June beetles were numerous to avoid this risk 

 even if it meant changing the rotation. 



The following is a brief summary of June beetle conditions 

 throughout the State: 



Albany county. June beetles were very abundant in and about 

 Albany, were reported as numerous at Ravena and evidences of 

 their work were very apparent along the West Shore tracks from 

 Wemple south to Ravena. They were so abundant at Feura Bush 

 as to cut off practically all the prunes in a small orchard. 



Allegany county. The insects were reported abundant by Mr 

 D. P. Crandall of the Belfast High School. 



Broome county. June beetles were reported numerous in the 

 vicinity of Binghamton. 



Chautauqua county. The insects were present here and there 

 in numbers, some farmers stating that the beetles were more abun- 

 dant than ever before. There was some damage to trees, especially 

 elms. 



Columbia county. June beetles were generally somewhat numerous 

 in both the northern and southern portions of the county, feeding 

 being very apparent here and there. 



Chenango county. The insects were very numerous about Norwich 



and the defoliation was estimated as rang'ng from 25 to 30 per cent. 



Delaware county. June beetles were abundant in some sections
