White circles sound like spiralling white fly. Get rid of them asap. Once they settle in you won't get rid of them.
OH.. MAN !!! NOT another bug to put on my enemy list!!( Know your enemy LIST )
thanks for your info Moshman.
Usually it attacks the tree in front of the house and they also attacked my roses. now not more roses in my garden.
i seen severe white fly infestation on my mother in law place. it killed a huge pepper plant.(3 feet in dia. width and 5 feet tall) she did not spay any insecticides because it was full of half ripe pods!!. after the harvest it was too late. the plant began to dry from tips to the branches.
