a moon-shaped cut in the skin near the hole. If this cut were 



not made, what would happen to the young larva as the fruit 



grew in size ? One beetle will 



lay from fifty to i oo eggs. A 



sort of gum forms around the 



hole. The stem of the fruit 



soon weakens, and it drops to 



the ground with the larva in it 



The larva then comes out and 



burrows into the ground. In 



about a month the full-grown 



beetle appears. Some fight 



the CUfCUlio by jarring the trees Fig. 61. The plum-tree curculio. a, the

 It is applied several times after the blossoms have fallen. 



OTHER INSECTS. New insects are constantly appearing, 

 being brought in from other countries in fruit and nursery 

 stock. When first introduced, these insects increase very 

 rapidly, since their natural enemies are not always brought 

 with them at the same time. Sometimes they come later on.
