SiK. — The following' i-eport on "The Grape Koot-AA^oi'ni •' con- 

 tains tlie results of investigations made b}^ Professor M. \. Slinger- 

 land of an insect pest new to !N^ew York grape-growers which has 

 recently appeared in injurious numbers in some of the vineyards in 

 the great Chautauqua grape region. Apparently the insect has 

 never before been recorded as injurious to New Y ork vines. It is 

 to be hoped that its ravages in our State may be limited, for it is 

 the most serious and dangerous insect enemy which lias yet made 

 its appearance in our vineyards ; as it feeds both on the roots and 

 leaves, and is proving a dilhcult pest to control. It is capable of 

 killing the vines outright, and when present in injurious numbers 

 it usually seriously weakens or stunts the vines. New Y^ork grape- 

 growers should not fail to familiarize themselves with the pictures 

 and descriptions of this new pest and its work. 



It is believed that the information contained in the following 

 pages may help to avert the injury that is threatened, and the 

 report is submitted for publication under chapter J:30 of the Laws 

 of 1899.
