314 LIFE STORIES OF AUSTRALIAN INSECTS. 



to pass the remainder of its life in the fruit; so it 

 cats a tunnel to the outside of the apple, and then 

 finds its way down to the rough bark of the tree, 

 or perhaps to the ground. If to the latter, it soon 

 gets back to the tree, where it possibly rests in 

 a crack of the bark and covers itself with dense, 

 cobweb-like felt, under which cocoon it casts its 

 skin and changes to the pupa or resting condition, 

 remaining thus from one to three weeks, when the 

 pupal cover is cast off and the moth appears. The 

 second brood of moths lay their eggs on the leaves, 

 twigs, or even on the half-grown apples ; a favoured 

 spot seems to be" where a leaf or another apple is 

 touching. The larva at once eats into the fruit. 

 The pupae from this brood often hibernate, and thus 

 give rise to the moths of spring. Quinces and pears 

 may be attacked in a similar way to the apples. 

 A spray of arsenate of lead has proved an effective 

 remedy, 2 lbs. of lead being mixed with 50 gallons 

 of water. The lead will remain a considerable 

 time in suspension in the water, and does not easily 

 wash off. In New South Wales it is compulsory 

 to spray trees three times within nine weeks from 

 the fall of the petals. The spray is a very fine one. 

 and the fii'st spraying is directed particularly to 

 the flowers just after the petals fall and before the 

 calyx has closed over, so as to poison the tiny grub, 

 which so generally makes for the calyx end of 

 ihe fruit. 



A fold of hessian or an old bag is often tied 

 around the tree in such a way that one part falls 

 over the other. The larvae which reach the earth,
