Causes of leaf curl?

[spyfferoni]

I have several of my plants that have leaves curling up. Some of the plants only have some of the leaves doing it, while others the whole plant seems effected. I hope I don't have the tomato Curly Top virus. I noticed some black aphids? on the plants and some of the undersides of the leaves are shiny, like something or the plant has oozed something on the leaf. I'm wondering also if the Cucumber Mosaic virus causes curling---I have some plants that look like they might have that---from what I saw on the tomato disease photo gallery. I need to get some new batteries for my camera, and then I'll try to take some pictures tomorrow. If I do have either or those viruses, is their anything that can be done? Also, can weeks of temps in the high 90s and triple digits cause leaves to curl?

Thanks,
