THE QUINCE. 137 



Japan and Chinese quinces are only for orna- 

 ment. 



INSECTS INJURIOUS TO THE QUINCE. 



The Quince Ciirculio {Oonotrachelus cratcegi). 

 This is a broad-shouldered, snout beetle, of an 

 ash gray color, larger than the plum curculio, 

 which appears in June, and deposits an egg in a 

 round hole, punctured in the fruit. The larva 

 burrows in the fruit near the surface, but does 

 not go to the core. The beetle also feeds upon 

 the quince, burying itself completely in the fruit. 

 Should it be found numerous it may be de- 

 stroyed by jarring the tree as described for the 

 plum curculio. 



The Round-headed Apple Borer, before de- 

 scribed, is the borer which is so injurious to the 

 quince. The remedies are the same, and since 

 the quince is so much smaller and more sensitive 

 than the apple, it is the more important that the 

 trees should not be neglected. 



The Pear Slug, a leaf crumpler, and a bag or 

 basket worm are sometimes found upon the 

 foliage, but are not seriously injurious. 



For Rust, spraying -with one of the fungi- 

 cides is recommended.
