or in the crotches of trees, in the cracks and crevices about packing 

 houses. In the spring they pupate and later the moths emerge. 



The loss from this insect can be almost entirely prevented by 

 the proper application of arsenicals. Thorough cleaning up of 

 places where the insect finds shelter for the winter will also have 

 its bearing on the control. 



LESSER APPLE WORM. 



This is a small insect, the larvae of which very much resembles 

 that of the codling moth, and is probably many times mistaken for 

 it. In its habits and life history it is similar to the codling moth, 

 except that it appears later in the season. The injury from the 

 lesser apple worm may usually be distinguished from that of the 

 codling moth, owing to its tendency to burrow just beneath the 

 skin and to make a much more tortuous burrow than does the 

 codling moth. The greater amount of injury from lesser apple 

 worm occurs on the sides of the apple instead of at the calyx end. 

 The treatment for this insect is included in that for codling moth. 



CURCULIO. 



The plum curculio is a small, snout beetle that is responsible 

 for the "stings" which are frequently so numerous and conspicuous 

 on young apples shortly after the blossoms fall. This is, without 

 question, the most difficult pest to control that infests the Missouri 



orchards. Although its 

 distribution is not so gen- 

 eral as that of the codling 

 moth, yet in localities 

 where it does occur it 

 causes proportionately 

 greater injury to the 

 fruit than does the codling 

 moth. This pest is par- 

 ticularly significant in its 

 relation to the brown rot 

 of peaches and other stone 

 fruit. The punctures that 

 it makes in the skin of 

 these fruits, either for the purpose of feeding or depositing eggs, 

 make ideal places of entrance for the brown rot fungus. 



There is but one brood of the insects during the year. The 



Ailult curculio. (From Quiiit.-ince and Jcnne. )
