THE CURCULIO. 



PLATE III. 



1. Plum, June 3, Egg of Curculio hatched, and the young grub eating its way. 



2. Same Plum, June 3. A slice cut off, exposing the passage-way of the grub. 

 a. The grub, the natural size at this date. 



3. Green Gage, June 14th. Several Curculio marks. The globules of gum indicate that the eggs have 



been hatched. 



4. Peach, June 14. The particles of gum here indicate the same thing as in the Plum, Figure 3. 



5. Washington or Bolmar Plum, June zoth. Fruit fallen, and the grub emerged from hole at a. 



6. Peach, June 24. On the ground, a grub having just escaped. 



7. Pear, June 24. Showing blemishes from punctures of the Curculio. 



8. Perfect Cherry, June 25. 



9. External appearance of Cherry containing a grub of the Curculio when nearly full grown. 

 10. The same Cherry when opened. 



9 and 10. The kinds of Cherries which birds prefer. 



THE dark line leading from the puncture in Fig. l , is a common appearance in 

 the progress of the Curculio, but not universal. It indicates unmistakably the 

 destruction of the Plum. 



Fig. 2 shows that the young grub does not proceed at once towards the centre 

 of the plum, but soon after this it will be found feeding round, or in the pit itself 



The globules of gum on Figs. 3 and 4 are proof positive that nothing can save 

 such fruits. Apples also sometimes show gummy exudations from the wounds made 

 by the Curculio, but this gum does not become so concreted as in the plum and 

 peach, remaining soft and sticky. 



Peach-growers will recognise Fig. 6 as a kind of peach too often met with 

 under their trees about the last of June and the early part of July. 



Fig. 7 represents a very common appearance of the pear. 



In a plantation of Pear trees standing by the side of an old neglected Apple 

 orchard, I have caught several hundred Curculios in less than an hour, by jarring 

 thirty or forty trees. But as soon as the neighboring apples were large enough the 

 pears would be deserted. The Pear, though often injured, suffers less from this
