Garden Pests and Diseases: Rose under attack!, 1 by ignote

I got this Honey Dijon rose as a bareroot this spring. It grew splendidly and undisturbed for a good three weeks. I had several buds on the plant, and one that was about ready to bloom. Then one mysteriously disappeared, and I noticed that a few smaller ones looked peculiar and dried out, like they weren't developing any more. One had a spot bored down to the center of the bud, and it was dead. Do I have some sort of bug infestation, or animal problems? Both? A very similar thing happened to my Ebb Tide that is in the same bed. All buds are gone on that one. :( The only critter I could find was a very tiny, bright green bug on the underside of a leaf. I sprayed with a multi-purpose pest control tonight, 'cause I'm pretty worried. The Ebb Tide stopped producing new growth all together, not sure if that's relevant. Also, some of the newest leaves turn brown before they ever have a chance to get full-sized.
