Red Pine Attacked by the White Pine Weevil 



In July, 1918, in a plantation of mixed white pine {Finns strobus 

 L.)> red pine (Pinus resinosa Ait.), and Scotch pine (P. sylvestris L.)> 

 but consisting mainly of red pine, on the South Mountain Reservation, 

 near Orange, N. J., the white pine weevil (Pissodes strobi Peck), 

 was observed infesting young shoots of the red pines. The trees of 

 all three species, several thousand in number, and covering several 

 acres, were about eight years old and varied from five to eight feet in 

 height. Numerous white pines were also infested, and where these 

 trees adjoined the red pines, the latter were most severely affected. 

 However, only comparatively few red pines were affected, 24 being 

 counted. Specimens of the injured red pine were sent to Dr. A. D. 

 Hopkins, of the U. S. Department of Agriculture, who confirmed 

 the writer's identification. The Scotch pines were uninjured. 



The case is noteworthy since it is the first specific record, so far as 

 the writer can ascertain, of infestation of the red pine by the white 

 pine weevil. The red or Norway pine has long been regarded as 

 entirely free from this pest, and on this account, as well as its freedom 

 from the dreaded blister rust and its comparatively rapid growth, is 

 being looked upon with increasing favor by planters in the Eastern 

 States. 



It is not to be inferred from the above that the tree is likely to 

 become generally infested, and yet it is a matter of considerable 

 importance to know that under certain conditions, perhaps mainly the 

 immediate proximity of badly infested white pines, it may become 

 attacked. Sporadic attacks on the Scotch pine, under similar circum- 

 stances, have also been noticed by the writer near New Haven, Conn. 

 Dr. Hopkins records the species on "native and cultivated spruces, the 

 jack pine and very rarely the pitch pine and other eastern pines."^
