CODLIN MOTH, 



Codlin Moth. CarjwcajJsa 2}0)nonella, Limn. 



Carpocapsa roMONELLA. — Moth, natural size and magnified ; caterpillar ; 

 injured Apple. 



Codlin Moth attack is one of the regularly recurring yearly 

 troubles of the fruit-grower, and although the " maggotty" or 

 "worm-eaten" condition of the young fruit, which we know 

 only too well as causing it to fall in quantities before it is 

 large enough to be of any use, may sometimes arise from 

 Apple Sawfly presence, or from other infestations, yet for the 

 most part the mischief is due to the larva of Carpocapsa 

 2)omonella. 



Other of our orchard fruits are also liable to this infestation. 

 Pears are sometimes much injured; Quince, Plum, Peach, 

 and Apricot are sometimes attacked ; Walnuts have been 

 found to be infested ; * and this species has been recorded as 

 having been bred frequently from Sweet Chestnuts. 



The caterpillar, or larva, when full-grown, is from rather 

 under two-thirds up to three-quarters of an inch in length ; 

 at first it is whitish, later on more or less of a pink or flesh- 

 colour. The head when young is blackish, later on lighter 

 in colour ; the shield on the segment next the head varies 

 similarly in colour with age of the grub, and so does the tail 

 segment. It has "eight little black dots or warts on each 

 segment, so arranged as to make two rows down the back, 

 and one row on each side" (Frazer S. Crawford). The cater- 

 pillar has three pairs of claw-feet ; four pairs of sucker-feet 

 beneath the body, and another pair at the end of the tail. 



The cocoon is given by Dr. L. 0. Howard as " white inside 

 and greyish outside, and usually covered somewhat with bits 

 of bark or minute fragments of whatever substance the worm 

 happens to sr)in on."
