' r ><) INSECTS AFFECTING THE APPLE. 



Other Apple Insects. 



The apple is subject to attack by many insects be- 

 sides those discussed in the foregoing pages, which, 

 however, include the most injurious pests. The 

 trunk and branches are occasionally infested by the 

 Scurfy Bark-louse (which will be found described on 

 a later page as a pear insect) ; the leaves are some- 

 times eaten by various caterpillars besides those 

 mentioned . and the fruit is attacked by the Plum 

 Curculio, as well as by the three species we have dis- 

 cussed. But the treatment recommended will keep 

 in check not only the insects included in our list, 

 but also nearly, if not quite, all of these various 

 other pests. 



Summary of Treatment. — Young apple trees 

 should be examined for insects as soon as received 

 from the nursery. If any Woolly Aphids are pres- 

 ent on the roots or branches, the affected part should 

 be treated with kerosene emulsion. If the ragged 

 cases of the Leaf Crumpler are attached to the twigs 

 they should be removed and burned. 



As soon in spring as the blossoms have entirely 

 fallen, the trees should be sprayed with Paris green 

 and water — 3 ounces to 50 gallons. The application 

 had generally better be repeated ten days or two 

 weeks later. This will check both the fruit and leaf- 

 eating insects.
