sucks the juices. This causes brown spots to be found 

 throughout the pulp of the apple, and finally the fruit decays. 

 Frequently the inside will be wholly worthless, while the exte- 

 rior surface of the fruit shows no indications of the presence 

 of the maggot. As the maggot is inside, wholly out of reach 

 of sprays, it cannot well be controlled by spraying, thougii 

 it is said that where trees have been properly sprayed for 

 codling moth the attack of the apple maggot has been some- 

 what lessened. As a rule, however, we can do nothing more 

 than to destroy the infested fruit, and to endeavor to grow 

 such varieties as are not subject to its attack. 



Plum Curculio. (Coiiolrachclus ncnnpliar Hbst.) 

 Apples have been seriously injured by the plum curculio 

 during the past few years. The adult beetle punctures the 

 young fruits for the purpose of food, and the females deposit 

 their eggs inside. The tgg, is white, and oval in shape, and 

 around the tg^ puncture a crescent-shaped mark is cut to 

 prevent the growing fruit from injuring the egg. It is found

that many punctures are made and even the crescent mark is 

 cut in many places w'here the eggs are not deposited. When 

 the egg hatches, the young lan^a tunnels through the pulp of 

 the fruit, but, instead of causing it to decay, as is the case 

 with the apple maggot, the wound usually heals, and a hard 

 streak is formed through the apple where this tunnel was 

 made. The general effect is to cause the apples to grow 

 irregular and knotty, and of course the quality is much injured 

 as well. This injury was supposed to be caused by the apple 

 curculio, but this insect is a rather rare species, wdiile the 

 plum curculio is extremely common, and attacks the plum.
