the pits of fruits. So far as seen, none had emerged on this date. 

 August 15th or 20th would probably be a safe date to set as a limit 

 •^beyond which it would be unsafe to delay gathering the stung fruit. 

 •^On the other hand this work should not be done earlier than July 

 •15th, else the larvae from late deposited eggs would escape. 

 ••(2) Prof. Gillette and others have recommended the gathering 

 'and destroying of the adult beetles early in the spring. This is th;^ 

 easiest done, as with the plum curculio, by jarring the beetles from 

 the trees into a suitable contrivance, described below, from which 

 they may be taken and destroyed. By so doing, early in the season, 

 the beetls taken will be prevented from either destroying buds and 

 ilowers or puncturing young fruit. 



The essential features of a curculio catcher are an expanse of 

 canvas or cloth, supported on a frame work. A convenient and 

 approved form is one in which the canvas is supported on a wheel 

 and handles, which resemble a wheel barrow. On the opposite side 

 of the wheel from the handles is a long opening in the canvas so 

 arranged that the wheel may be pushed close to the trunk of the 

 tree, thereby bringing the canvas under practically the whole tree. 

 Then the tree, if small, or the separate limbs, are suddenly jarred 

 to dislodge the beetles, which are gathered and destroyed. 



Such a catcher as is above described is designed for an orchard 

 of a considerable number of trees. A simple sheet spread on the 

 :ground will serve for a small number of trees.
