26i ANNUAL REPORT 



REMEDIES. 



Syringing the tree with a mixture of Paris Green or London Pur- 

 ple and water. Jarring the trees and gathering the caterpillars 

 which will drop and hang suspended by a silken thread; search- 

 ing for and destroying the eggs before they hatch, or trapping tlie 

 females by pasting bands smeared with tar or other sticky substance 

 about the trunk of the trees. The apple tree borer is the larva 

 of a beetle and is very destructive to the trees. The female lays 

 her eggs upon the bark in June or July; after hatching, the young 

 eats its way through the bark and makes roads or burrows upward 

 next the sap wood, just the size of its body, enlarging them as it 

 increases in size, pushing the sawdust like chips out at the hole 

 where it entered, and finally eats a large cavity into the heart- 

 wood to form a place for its last transformation. 



REMEDIES. 



Rub the bark around the trunk and lower branches with soft 

 soap about the first of June. Search out the burrows and cut 

 out the grub with a sharp knife or probe them with an awl or wire 

 and plug the hole with hard soap. 



OYSTER SHELL BARK LOUSE. 



This insect can be destroyed or kept from the trees by giving 

 them a wash with lye or strong soap suds every year in June. 

 Kerosene applied with a paint brush is said to be effectual. 



APPLE WORM OR CODLING MOTH. 



This insect is so destructive to our fruit that it deserves more 

 than a passing notice, which the length of this paper and time will 

 not permit. It is demonstrated that there are two broods of them 

 in a season. For the first the moth deposits the eggs one at a time, 

 in the calyx end of the apple, soon after it is out of blossom. 

 The life of the insect, from the egg to the perfect moth, is from six 

 to eight weeks, when the moths immediately pair and deposit their 

 eggs for another generation in the now half-grown plant. These 

 latter leave the fruit in six or eight weeks and crawl away into 

 secure hiding places to pass the winter in the larva state, and in 

 spring transform into perfect moths. They are often found in 

 winter concealed under the hoops of and in the creases of apple 

 barrels and bins.
