I usually observe mealy bugs at the roots of paradoxa plants that go dormant for me. The remedy is to remove all the brown old leaves and repot the plant in new media. Always works. Sometimes, I split the plant into 2-3 parts and get a few new plants.
I read the abstract on one paper that you can kill root mealybugs by immersing the roots in 120°F water. The test plants were left in the water long enough for the center of the root ball to reach 110°F (about 20 minutes). Something tiny like D. paradox probably only needs to be dipped for a few seconds. Bare root. Might be worth trying on a few plants. One of those DIY pest control books I glanced through in the library said you can kill mealybugs by spraying with hot water (90-120°F). I tried this out and it seems to work but you never know with mealybugs. 120°F shouldn't bother D. paradoxa much.
Grand Hotel... always the same. People come, people go. Nothing ever happens.
It just wasn't doing anything. I saw a little green and knew it had some life to it. The other 2 plants I received were growing. This one is now doing better than the other 2.
dunno. have never seen root mealybugs on this one. have not seen mealybugs in the indoor collection either. OTOH most of my paradoxa do not really have roots. compared to ordensis or fulva, paradoxa seems to only have roots to prevent the plant from blowing away in the wind.....
In Sept. I recieved a few Petiolaris plants and took a few pullings from them. I put these in a container with water, closed the lid and apparently forgot about them.
Then yesterday while mucking around in the g/h I see this container and wondered what was in it! (funny how things get lost huh :-\ ) To my surprise there are plants in there- a couple doing quite well given the circumstances...!
Pretty cool =)
Hey Jimscott, hows that D. paradoxa doing these days??

@adnedarn: what species do you have sprouted in your photo? Did you just take cuttings or were they more pulling-like with portions of the main plant attached?
A cold one that is not cold is scarcely a one at all. - SB
I believe it was petiolaris. They were pullings of the main plants when I got them in, generally a few leaves as a group along with the white of the main plant.
