AGRICULTURAL EXPERIMENT STATION. 



ASH-GRAY PINION. 



Lithopliane antennaia, (Walker.) 

 Though not abundant we found quite a number of apples the 

 past season apparenth' injured b}-- this insect. The perfect insect 

 is a DQOth. It is the larva that does the injury by boring into the 

 the young fruit. 



FIG. 26 



In Fig. 26 is shown the moth and the larva at work. The moth 

 is dull ash-gray color with variegated fore wings. The larva pale 

 green, spotted with cream color and with a broad lateral band of the 

 same shade. Hand picking is the only remedy we know or can 

 suggest. 



THE PEAR TREE SLUG. 



Selandria cerasi, Peck. 



Specimens of the above insect were received the past season and 

 reported as doing great injurv to the foliage of cherry and plum 

 trees. Mr. Eben Bickford of South Newburgh says, ''they appeared 

 on viix cherrj' trees about ten or twelve j'eais ago and destroyed m^' 

 trees in two or three years. Eternal vigilence has been the price 

 of chei'ries since. I have found no one who has seen anything like 

 them, and I send them to _you in hopes you will be able to name 

 them and suggest a remedy. They will live on and destroy Damson 

 plum trees when they cannot get cherry, but I have not seen them 

 on an}- other. They do not travel far, as my neighbors, only twenty 

 or thirty rods off, do not have them." 



This pest was fully considered in 1790 by Prof. Peck of Mass., 

 in an article entitled "Natural History of the Slug worm" which
