THE CIGAR CASE-BEARER. 4] 
ENEMIES. 
PARASITES. 
Fletcher in 1897 reported a hymenopterous parasite of this insect, 
Microdus laticinctus Ashm., from Port Hope, Ontario. 
At North East, Pa., at the time of the emerging of the adults, 
another hymenopterous parasite, Zabrocytus sp. (fig. 12), as deter- 
mined by Mr. J. C. Crawford, was reared in considerable numbers. 
About 10 per cent of the transforming insects were parasitized. 
PREDACEOUS ENEMIES. 
The writer found that the eggs of the case-bearer were extensively 
destroyed by a minute yellow mite, which during the egg period was 
very abundant all 
ever the orchard. 
The larve of the 
lacewing fly 
(Chrysopa oculata 
Say) and various 
species of ladybird 
beetles vigorously 
attacked the eggs 
and larvee. 
METHODS OF 
CONTROL. 
A full account 
of the results of Fic. 12.—Habrocytus sp., a parasite of the cigar case-bearer. 
A Greatly enlarged. (Original.) 
the various spray- 
ing experiments carried out in Canada by different fruit growers will 
be found in Fletcher's report for 1894 as entomologist and botanist for 
the Canadian experimental farms, pages 201 to 206. It was well 
demonstrated that the insect can be held under control with either 
a kerosene emulsion or a Paris green spray applied in the early spring 
before and while the leaf buds are opening. 
In orchards regularly treated with arsenical sprays for the codling 
moth the cigar case-bearer, if present in orchards, will undoubtedly 
be kept in check.
