196 AGRICULTURE ON THE PACIFIC SLOPE 



Wireworms are often troublesome in vineyards planted 

 on land where hay or grain has previously been grown. 

 When they get into the vineyard the only way is to dig them 

 out from around the roots. They do not do very much 

 damage except where they are very numerous. (California 

 Experiment Station, Bulletin 192; Washington, 4.) 



Weevils. These are small beetles with peculiar snouts. 

 They are found in grain, peas, beans, and other seeds. The 

 clicking noise of their jaws may be distinctly heard when 

 the ear is placed near seeds among which they are at work. 

 Grain may be freed from them by placing it in a box and 

 making the cracks tight by pasting paper over them, then 

 placing a saucer of carbon bisulphid on top, and leaving it 

 for twenty-four hours. Use one pound of carbon bisulphid 

 to one hundred bushels of grain. Carbon bisulphid is 

 poisonous and easily catches fire if brought near a "light. 

 The weevil in peas and beans may be killed by heating 

 sufficiently to kill the weevils without injuring the seeds. 



Plum curculio. In the East a beetle 

 called the plum curculio or plum weevil 

 damages the plums in much the same way 

 as the codling moth damages the apple. 

 (Utah Experiment Station, Bulletins 49, 

 65; New Mexico, 68; Washington, 38.) 



Ladybirds. These beautiful little

bird, which eats f they feed R the ^ }J ce and 



scale insects and J 



plant lice. help to keep them in check. The 



cottony cushion scale was a very serious pest in this state 

 until the Australian ladybird was imported to keep it in 

 check. It has provecT a great success for this purpose.
