I've seen no reports of midge anywhere near Arizona, so I'd doubt that's what it is. If you aren't at high altitude, it's hard to keep roses growing and blooming through an Arizona summer.

While we do have midge in some areas, now isn't the season. If it looks like midge damage, I'm guessing it's a combination of heat, low humidity and possibly underwatering. Curling, browning leaves are far too common during a low-desert summer.

Usually, increasing the length of the watering cycle, maybe providing some afternoon shade and holding off on fertilizers and pruning is enough to help the roses withstand the rest of the summer. They should perk up again after Labor Day.

Did you plant any potted roses? The midge would come in the soil, so you may have imported them. Do a search on this forum for rose midge and you will likely find some excellent photos of the damage. Judge from there.
