2G4 KEPOilT OF THE DEi'AKTMENT OF EXTOMOLOGY OF THE 



Two species of apple leaf miners were uuusually comiiiou in 

 Western New York orchards, but caused little injury as tliey do 

 not appear until late in the season. 



Peaches in an orchard near Rochester were injured by the 

 tarnished plant-bug, which sucked the juice from the young- 

 fruits, causing them to wither and become permanently distorted. 



I. THE FOREST TENT-CATERPILLAB. 



Clisiocampa disstria Hubn. 



The forest tent-caterpillars appeared again last spring in suf- 

 ficient numbers to cause nnuch annoyance, and in some cases 

 serious loss. The questions as to whether the caterpillars appear 

 to be increasing or decreasing in numbers, taking the State as a 

 whole, and whether they are becoming more destructive to 

 orchard trees are of importance to fruit growers. To secure 

 data bearing on these questions, circular letters were sent, as 

 last year, to correspondent's in nearly every county in the State. 

 t>'umming up the reports and adding our own observations, the 

 xtent and character of the outbreak were approximately as 

 ."ollows: In most of the western Counties the caterpillars were 

 widely scattered, the same as last year. In Allegany and Steu- 

 ben Counties, they were less in numbers, as a rule, in the maple 

 groves, woodlands and orchards that were extensively infested 

 last year; but much more abundant in neighboring localities in 

 which they appeared in less numbers the year previous. The 

 reports from Cortland, Chenango, Madison, Oneida and Herkimer 

 Counties state that the caterpillars were usually more numerous 

 in the forest trees and orchards than last year but less in num- 

 bers on shade trees. The reports from Herkimer County indi- 

 cate that in that section they were somewhat lesis abundant 

 in forest trees, but more numerous in orchard trees. Similar 

 reports came from Saratoga and Washington Counties and tlie 

 Mohawk and Upper Hudson valleys. In the northern part of 

 the State, especially St. Lawrence, Franklin and Clinton Coun- 

 ties, there is a reported decline in numbers.
