The Round-Headed Apple-Tree Borer. 



This insect is now very widely and generally known. It prefers 

 thq apple, but is at home in the pear, quince, and mountain ash. 



The eggs are depos- 

 ited late in June and 

 during July, one in a 

 place, on the bark of 

 the tree, near its 

 base. Within two 

 weeks the young 

 worms are hatched, 

 and at once com- 

 mence with their 

 sharp mandibles to 

 gnaw their way

through the outer bark to the interior. 



The soap remedy is probably as efficacious as any, being readily 

 obtained. Take soft soap and reduce to. the consistency of thin 

 paint by the addition of a strong solution of 

 washing soda in water. Apply to the bark 

 of the tree, especially about the base or 

 collar, and up to the crotches. If applied 

 during the morning of a warm day, it will 

 dry in a few hours, and is not easily dissolved 

 by rain. This should be applied early in 

 June and a second time during the early part 

 of July. 

 The Flat-Headed Apple^Tree Borer. 



1 This pest is common almost everywhere. 

 It attacks the pear, plum, and sometimes the 

 peach as well as the apple. It does not confine its work to the 

 base of the tree, but affects the trunk more or less throughout, and 

 sometimes the large branches. 



As a preventive measure, there is nothing better than coating 

 the bark of the trunk and larger branches with a mixture of soft soap 1 

 and a solution of soda, as recommended for the Round-headed 



Borer. 



, The Woolly-Louse of the Apple. 



This is the same species as the'./ Aggie-root Plant-louse, ;but in 

 this form the insects attack the trunk and limbs of the apple-tree,
