In some orchards it was difficult to find one cherry out of five that did not contain a maggot. A few experiments on control measures were tried, but there was not time to do the work thoroughly. I am expecting to study these pests more carefully next year. Apple Maggot (Rhagoletis pomenella).

Agriculture.) and our Department, I shall not make any further remarks on it than merely to say that I hope that next year may be more favorable for the study of this insect than this has been, and that if so, we may be able to finish the investigation in Ontario unless some new phase of the subject presents itself to us. Rose Chafer {Macrodactylus suhspinosus). In most districts the Rose Chafer did much less damage than usual, but in one or two cases it appeared in new districts and did considerable damage to grapes, raspberries, and young cherry.
