49 



holes in corrugated pasteboard whieh had been placed in the breeding 

 jar, consequently no observations of the pupal stage could be made. 



The Adult. — The adult (Fig. 14) is rather small, length of body being 

 about three eighths of an inch in length and has a wing expanse of 

 about seven eighths of an inch. Color ocherous ; fore wings with three 

 dark transverse bands and numerous dark spots; posterior wings with 

 numerous dark spots. 



Method of Attack. — The caterpillar enters the fruit invariably at 

 the stem end, works around and into the pit. which many times 

 causes the same to split. Others were observed apparently devouring 

 the flesh and making deep cavities in the fruit, all of which reduces the 

 commercial value of the same. 



Summary. — Mr. W. T. Kirk, in Leaflet No. 29, Xew Zealand Dept. 

 of Agric, speaks of this insect as follows: 



This is one of the native species, which is found on many indi- 

 genous plants and has now become fond of introduced fruits. 

 It is by no means uncommon to find the caterpillar of this moth 

 within the stone of the peach, where it remains feeding on 

 the kernel until full grown. The pupa or chrysalis is also found,

thus showing that the whole period comprising these two stages 



is spent within the fruit. Considerable damage has been done in 



some orchards by this insect. Its attack retards the progress of 



the fruit and its presence, which frequently causes the stone to 



split, reduces the market value of the affected fruit. 



From the foregoing account the reader will see that the quarantine 



service is maintaining its record and is on the alert at all times to 



accomplish the primary purpose for which it was created — prevention 



of increase in the cost of production.
