INSECTS INFESTING THE APPLE TREE. 71 



CHAPTER XXVI. 



The Gray Bark Eating Weevil. (Cal.) 



( Thricolepis simulator. — Horn.) 



Order, Coleoptera ; Family, Curculionid.e. 



[A small, light grayish snout beetle, feeding upon the bark 

 of the small branches or twigs of apple trees early in the 

 Spring.] 



Early last Spring (1883), specimens were received from fruit 

 growing districts located at least one hundred and fifty miles 

 apart, of a small, light grayish colored weevil, reported as eat- 

 ing the bark and buds of apple trees. 



This beetle (Fig. 32, Plate 1,) measures from one and one 

 half to one and three fourth lines in length ; the color is 

 grayish brown, but is covered with fine white scales, giving it 

 a light grayish color. The larvae probabl}^ feed on the roots 

 of plants, but as this species is only reported this Spring its 

 natural history is not known to me. 



Remedies. — Early in the Spring spray trees infested the pre- 

 vious year with No. 5 or 7 ; repeat in two weeks. This will 

 prevent the beetle from eating the bark.

[Living upon the twigs of the apple, peach, apricot, almond 

 and plum trees ; a green leaf-hopper, shaped something like a 

 beechnut, with two short spines jutting out horizontally from 

 each side of the anterior end, having some resemblance to the 

 horns of a bull or buffalo.]
