580 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



egg-scars and feeding-punctures cause apples to become gnarly, 

 this being particularly true of summer varieties, which are often 

 rendered worthless, and even winter sorts are blemished by the 

 scars which also furnish points of attack for rots. 



Control. Frequent cultivation while the pupa 1 arc in the soil 

 in midsummer will throw them to the surface and crush many of 

 them, and has been found to aid materially in the control of the 

 pest. As the larvae often develop in the fallen fruit, it is w r ell

to gather it every few days and destroy it before the larvae have 

 left it to pupate, which will also aid in the control of other fruit 

 pests. The beetles have a habit of " sulling," " playing possum," 

 or feigning death, when suddenly disturbed, and will drop to the 

 ground if a limb is jarred. This has given rise to the common 

 practice of jarring peach, plum, and cherry trees and colecting 

 the beetles on frames beneath them. This may be done with 

 simple frames covered with canvas, a frame being placed on either 

 side the tree and a flap extending from one over the edge of the 

 other, from which the beetles are picked up, or a regu'ar curculio-
