I have some Explorer roses that I planted this year (Edmonton, AB). In the past 2 weeks some insect is eating my buds. The buds have a single hole in them that goes to the centre of the bud. The hole is about 1/8 to 3/16 inches in diameter. Whatever is eating them hollows out the bud. They seem to be eaten at night because I usually discover the newly eaten buds in the morning even though I inspected them the nigh t before. I have shown the damaged rosebuds to the garden centre where I purchased the roses. They think it is a rose chafer and suggested using rose dust. Since applying the rose dust I have lost 3 more buds. I have not seen examples of the damage that the rose chafer does to a bud so I am not convinced this is the culprit.

Has anyone experience this too? What can I do to stop the pests?

Jerry, I've seen this on my roses too. In the past, I have treated my roses with cygon in the spring, which is a systemic. Whatever the bug is, it does not like the cygon. However, I did not use the cygon this spring, am watching my roses closely, and have seen nothing so far this year.

Thanks Joanne. I have used cygon on my birch to control leaf miner a couple of years ago and it worked very well. I have not thought of using it on the roses. It is probably too late to use it this year. I will give it a try next spring.
