 and feeds for a time on the buds before the fruit is set. 

 During this period it may be destroyed by spraying the 

 opening buds with poison. If sprayed just after bios-, 

 soming, many weevils will be killed before they injure 

 the fruit. 



Another method of destroying the weevils depends 

 upon their habit of dropping to the ground for protection 

 if anything dis- 

 turbs the tree. 

 A cloth-covered 

 frame is placed
