gj INSECTS INJURIOUS TO FRUIT. 



pass a little to one side of the centre, it will be of a green or yellow-green color, and 

 much narrower, looking as if it had acted as a cord, tying the centre and circumfe- 

 rence of the apple together, and preventing its expansion in that direction, and thus 

 causing the depression. Apples, when wounded in this way, are not destroyed, only 

 deformed. They usually hang on the trees to maturity. The grub, from some 

 cause or other, perishes before reaching the vital part. This was the condition of the 

 apple crop in large sections of the country in 1 864. There had been a period of 

 nearly six weeks in July and August of excessively hot and dry weather, after which 

 very few living grubs of the Curculio could be found. The marks, as seen in this 

 Figure, where they had gone just so far, were very numerous. 



We sometimes encounter the grub of the Curculio in early peaches, as we do in 

 cherries, apricots, and early plums. 



Fig. 6 was taken from a tree of the Crawford's' Late at the time the sound fruit 

 was ripe. The puncture of the Curculio had caused it to rot. Gum had exuded 

 from near the stem, sticking it fast to the twig. Such specimens of fruit, still more 

 dried up and withered, may be seen on Plum, Peach, Nectarine, and Apricot trees, 

 often hanging on all winter. 



Previous to the Rebellion, cherries, apricots, early apples, and peaches, were 

 brought to the New York market from many of the Southern States, often from as 

 far south as Georgia. If there had been no other evidence that the Curculio was 

 common in that section of country, these fruits would have settled the question. 

 Terrible as this pest is with us and further north, when the same fruits from the 

 different sections were subjected to a comparison, the North would seem to suffer 

 least.
