thank you very much!
well for now I can find more mealy bugs. just that one and I did remove it from the branch.
I have 3 plants, outdoor, they are already in blossoming stage, since 15 august. After a overwatering problem + plants on top of too hot floor, beginning to ruin the roots, burned almost 50% of the leaves, they are now recovering. still had no need to spray them with nothing. For the same reason I don't know if I shouldn't just for the sake of prevention.
For what I read the male of the mealy bug is kinda a mosquito, possibly I saw a lot of those coming from the roots (beneath of the vase, from the holes) just before watering.
again, thanks for the help
stay well my friends
