458 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



arsenicals. By planting rows of early varieties, which flower 

 freely and produce an abundance of pollen near woods and 

 fence-rows where the beetles have hibernated and appeal* first, 

 they might be effectively trapped, and then destroyed. Although 

 the larvce cannot be reached with any insecticide, the beetles 

 feed more or less on the buds and foliage, and further experiments 

 should be made in spraying for them with arsenicals. In view of 

 the recent success in the use of arsenate of lead against the plum 

 curculio, we would suggest the thorough spraying of badly infested 

 beds with arsenate of lead 3 to 5 pounds per barrel, applying it 

 with an under-spray nozzle so as to thoroughly cover every bit 

 of foliage. This should be applied as soon as the buds commence 

 to form and probably a week later before they blossom, as it is 

 then that the beetles are feeding. Spraying at that season can do 

 no possible harm to the berries, and to spray after the buds are 

 injured is useless. The destruction of all trash and rubbish in 

 and around the fields during the winter will destroy some of the 

 hibernating weevils, and it will be well to avoid mulching the 

 beds where the beetle is troublesome, if the mulch is not abso- 

 lutely necessary, as it furnishes them the best hibernating 

 quarters.
