48 INSECTS OF ECONOMIC IMPORTANCE 



nates in the hollow seed shell until spring, when the 

 adults appear ; particularly injurious to early apples. 

 Control — Since the grub lives over winter in the 

 seeds, the apples under the tree should all be col- 

 lected and destroyed. 



The GREEN FRUIT WORMS "^ (Xyliiia antennata) 



(Xylina laticincrea) 

 Order — Lepidoptera 



In some seasons the larvae of several species of 

 noctuid moths attack apples and eat large holes in 

 the sides of the fruit; these larvae have become 

 known as the green fruit worms ; the larvae appear 

 in great numbers in May and June and do their 

 damage, then go into the soil to the depth of i to 3 

 inches where they make an earthen cell and spin a 

 thin cocoon and change to pupae ; there they remain 

 until September, when the moths appear and pass 

 the winter in sheltered nooks; some of the pupas 

 remain all winter in the soil. The moths come 

 from their hibernating quarters or from the soil in 

 March and April and lay their nearly globular, 

 ridged eggs singly on the apple and pear branches. 

 The larvae are not noticed until they become half 

 grown and are then hard to kill. 



Control — If the trees are known to be infested 

 they should be sprayed just as the tips of the buds 

 show green and again just before the blossoms open 

 with arsenate of lead, 3 pounds to 50 gallons of 

 water or lime-sulphur. 



The PEAR-LEAF BLISTER-MITE"" {Eviopkycs pyri) 

 Order — Acarina 

 This mite has become a serious pest of apple trees 

 in New York State within the last few years; it is 

 fully discussed under pear pests.
