ATTACKING THE FRUIT.

should also be visited once after the crop is secured. Some 

 persons prefer to use narrower bands, not more than four 

 inches wide, and fasten them with a tack, while others se- 

 cure them in their place by merely tucking the end under. 

 Usually the cocoons under the bandages are partly attached 

 to the tree and partly to the bandage, so that when the latter 

 is removed the cocoon is torn asunder, when it often happens 

 that the larva or chrysalis will fall to the ground, and, if it 

 escapes notice, may there complete its transformations. Wide- 

 mouthed bottles partly filled with sweetened water, and hung 

 in the trees, have been recommended as traps for the codling 

 moth, but there is no reliable evidence that any appreciable 

 benefit has ever been derived from their use. There is no 

 doubt that a large number of moths can be captured in this 

 manner, but it is a rare thing to find a codling moth among 

 them. Neither is the plan of lighting fires in the orchard of 

 much avail, since codling moths are rarely attracted by light. 

 It has also been asserted that syringing the trees, about the 

 time when the fruit is setting, with a mixture of Paris-green 

 or London-purple and water will deter the moths from placing 

 their eggs on the apples, and thus protect the fruit from injury. 



The fallen fruit should be 

 promptly gathered and de- 

 stroyed. It has been recom- 

 mended that hogs be kept in 

 the orchard for the purpose of 

 devouring such fruit; and, 

 where they can be so kept 

 witliout injury to the trees or 

 to other crops, they will no 

 doubt prove useful. 



This insect, while in the lar- 

 val state, is so protected within 

 the apple that it enjoys great 

 immunity from insect enemies. Nevertheless it is occasion- 

 ally reached by the ever-watchful Ichneumons, two species
