FESTS OF ORCHARD AND SMALL FRUITS 



Spraying with arsenate of lead or Paris green will readily poison 

 the adults because of the long time during wliich they feed on the grape 



foliage. The poison should be applied 

 just after the grapes finish blooming. 

 Vineyards that are sprayed regularly with 

 arsenicals for other pests, such as the 

 grape berry moth, will not find this in- 

 sect in evidence. If it is found that 

 many berries are infested, these should 

 be collected and destroyed.

The Quince Curculio 



{Conotrachelus crakegi Walsh) 

 Both the adult and the grub of this 

 species injure the fruit of quinces. The 

 former eats holes into the fruit, when 

 it is still small. The latter burrows 

 within the flesh, making wandering 

 cavities, and finally eats its way out 

 through the skin. Quinces that have 

 been punctured by the adult grow 

 misshapen. 



The adult curculio is a small, snout 

 beetle, one fourth of an inch long, its 

 body broadest at the middle and its 

 back marked with seven longitudinal 

 ridges. Eggs are laid under the skin 

 of the young fruit. The grubs enter 

 the ground when full grown, and re- 

 main there until the following spring. 



The only effective remedy is to jar 

 the beetles from the trees in the early 

 morning, catching them on sheets and 

 destroying them. The application of ^^^ 523. -Work of the Straw-
