[IBC] Insect, fungus or nothing to worry about?
I've recently noticed a bunch of dark brown to black "things" on my Ficus
trees. I've not noticed them on any of the other trees located right beside the Ficus. The "things" are small, hard and conform themselves to the curves of the small twigs on which they are located. Haven't seen them on any of the larger branches. When I pick them off, there is not scarring underneath and they come off fairly easily. Once removed, they resemble the carapice (sp?) of a small bug; but I don't see any live insects running/flying/crawling around anywhere. I've looked through all of the books I have and can't find anything that looks or sounds like what I'm seeing here. The plants are all indoors in my basement under lights. I'm able to keep the air moving fairly well and the humidity is maintained at 40 - 60%. Both of the "infected" plants seem to be doing fine - new leaves sprouting all over; but I'm worried that there is impending doom of which I'm totally unaware. Any help would be much appreciated.

If you squeeze one between thumb and forefinger, do they squish? Do they leave a tiny red spot on your fingers? Have you looked at them through a decent magnifying glass, a jeweler's loupe, or (best) microscope? Both "sides?" Do your trees look healthy? Leaves still bright green; no mottled pale green or (worse) yellow? They may be egg cases of something that has hatched and flown the coop. In which case, they should have been there for a while -- tho, perhaps a different color when the egg was "alive." Look for something crawling/flying around the trees, including non-Ficus. Something tiny -- probably. Consider scale as a possibility if they do squish. Jim Lewis - - Tallahassee, FL - Our life is frittered away by detail . . . . Simplify!

You have scale. Iris, Central NY, Zone 5a, Sunset Zone 40 "If we see light at the end of the tunnel, It's the light of the oncoming train." Robert Lowell (1917-1977) |
