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 over the orchard. The larvae of the lacewing fly {Chrysopa oculata Say) and various species of ladybird beetles vigorously attacked the eggs and larvae. „ ^.™__^ METHODS OF CONTROL,. Fig. 12.—Habrocytus sp., a parasite of the cigar case-bearer. Greatly enlarged. (Original.) A full account of the results of 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 Avell 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 kej^t in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
