Nevertheless it appears that the tarnished plant bug may cause serious injury to 

 these trees and judging from the habits of the insect this would not be at all surprising. 

 Stedman (1) quotes Weir, a practical nurseryman, as stating that this insect causes 

 very serious injury to the buds of root grafts of pear, plum, quince and mountain ash 

 stock; injury to peach stock has been well described by Haseman(6), Crosby & Leonard 

 (8)and others These last writers in their bulletin on this insect have given a very good 

 summary of the work of this pest on a large number of plants of economic importance. 



Taken altogether the tarnished plant bug may be regarded as one of the most an- 

 noying and injurious pests with which we have to contend, and the question of its con- 

 trol constitutes one of the greatest unsolved problems in the whole field of economic 

 entomology.
