THE CIGAR CASE BEARER. 



HILE at Mr. Harold Jones' fruit farm, at Maitland, on the 

 St. Lavrrence, last summer, we were shown this insect in 

 large numbers, infesting his apple foliage. Under the 

 direction of Mr. Fletcher, our friend Mr. Jones has been 

 conducting numerous experiments for its distruction ; and 

 last May a Bulletin was published by Mr. Slingerland, of 

 Cornell, upon this insect The most effectual remedy 

 seems to be a spray of kerosene emulsion early in June, 

 when the little cases begin moving about, and the buds are 

 opening ; and a second application about a week later. 

 Where the Bordeaux mixture is being used for apple scab 

 as buds open, Paris green may be added, and this 

 spray will check the cigar case bearer, and the 

 apple bud moth, which also needs treating at that 

 time. 



The emulsion should be made by dissolving 

 half a pound of hard soap in one gallon of boil- 

 ing water, to which, while hot, add two gallons of 

 kerosene. 



In order that our readers may be prepared 

 for this new insect enemy we may briefly sum- 

 marise its history by stating that the eggs, which 

 are laid in June, hatch out in July, and mine the 

 leaves until September, when they make a winter 

 case in which they hibernate, attached to a twig 

 (Fig. 905). Here the insect remains until about the 

 middle of April, when it attacks the opening buds, 

 the young leaves, the flower and fruit stems and 

 the young fruit. 



The accompanying engraving (Fig. 906) from 

 the bulletin above mentioned gives a very correct 

 idea of the appearance of the cigar case bearer at 



work,just as we saw him in Mr. Jones' orchard, and it can easily be imagined 

 that the leaves would soon be well skeletonized and the trees sadly debilitated 

 by his work. Towards the end of May the winter case is discarded for 

 a large one, which the insect manufactures from bits of the leaves, as shown 

 in Fig. 907, after which it begins the most damaging period of its existence. 

 Protruding from its case, it eats through the skin of the leaf and mines out the 

 tissue as far as it can reach and still hold to its case. Towards the end of 

 June they pupate, and soon the moth emerges and begins its work by oviposi- 

 tion.
