210 DESTRUCTIVE INSECTS. 



This weevil is an extremely difficult pest to control. Poi- 

 sonous and other sprays have not thus far given very encour- 

 aging results. It would be practicable to cover small areas 

 or valuable plants with a muslin protector, put on about a 

 week before the first blossoms appear. Grow as few staminate 

 plants as practicable.
