206 FRUIT INSECTS 



foliage. Young apple, pear, peach and plum orchards set near 

 or on locust clearings have been seriously injured in early 

 spring by the beetles swarming on to the trees and eating out 

 the buds, sometimes denuding and killing the trees. It is sus- 

 pected that the insect breeds on locust roots, but its life history 

 is unknown, except that the beetles hibernate in rubbish on 

 the ground. Thorough and frequent spraying of the opening 

 buds with arsenate of lead (6 or 8 pounds in 100 gallons) will 

 check the ravages of the beetles, which may also be jarred from 

 the trees on to sheets or plum curculio-catchers. Kerosene 

 emulsion diluted with 6 or 8 parts water is said to kill all that 

 are thoroughly hit. 



Remedies for flea-beetles. 



Experiments have shown that these flea-beetles can be effect- 

 ually controlled and many of them killed by one or two thorough 

 applications of a strong poison spray, as Paris green, 1 pound 

 in 100 gallons of water, or arsenate of lead, 4 or 5 pounds in 

 100 gallons of water. Bordeaux mixture alone often protects 

 the foliage from their attacks, and, combined with a poison, will 

 make a very effective spray. Apply as soon as the beetles 

 appear and make a second application a few days later, if 

 necessary. 



The Clover-mite 



Bryohia pratensis Garman 



This is a minute, spider-like, oval-shaped, reddish-brown 

 mite about j^q of an inch in length and with remarkably long 

 front legs (Fig. 192). Although it is closely related to the 

 common, two-spotted mite or so-called ''red-spider" of green- 

 houses, it lives mostly out-of-doors on trees, clover and grasses. 

 Throughout Canada and the northern half of the United States, 

 especially during dry seasons, this clover-mite often swarms 

 over the foHage of peach, prune, plum, apple, pear, cherry,
