I will cast my vote with Mr. Wilbert.
Mealy bugs can be found on leaves, branches, roots, and tubers.
I had just this weekend began to bring in several Amorpophallus,
along with other Aroids and other tropicals.
Several of my plants have Mealybugs, ( on the roots and tubers) as well.
You can have several over lapping generations once they establish themselves.
females can lay hundreds of eggs, after a month or so you are up to your ears
Treatment can be simple and low toxic. You can use insecticidal
soap, or any botanical insecticide. You could also use a horticultural
oil. All these products are applied as a spray. An "old" remedy used around here
by old timers, is to use a little bit more than a teaspoon each of dish soap and ammonia,
in a quart sprayer. which ever method you employ, be sure to thoroughly cover them.
I do try to clean off as many as possible, to lower the population, and effect better
coverage with the above mentioned products.
You can dab them with rubbing alcohol, on a Q-tip, or cotton ball.
They are a bit more harder to control when the plants are in pots, with the roots
contained within the growing media or soil mix. In some cases, drenching the media with
a bit more stronger product, might be needed, since you will have insects of varying stages,
within the media and the root system.
Hope this will be of use to you.
