Pest or Edema?

[Xanadu410]

Hey All,

Did a little looking around but not really sure. Is this some sort of pest or edema? Same color as the leaves and I haven't seen anything crawling.

I'm not familiar with edema in Catasetums. Not saying it doesn't exist, but I just haven't encountered it and haven't seen folks talking about it online.

On another note, you might want to spray for spider mites. The yellow stippling on new leaves looks suspicious to me.

I didn't see anyone online talking about it in catasetum either. Couldn't find anything that looked like this either though.

Ok I sure will do that. Should also mention that I received this plant via mail order a couple weeks ago.

As for my Catasetinae types that I haven't begun watering what would you suggest about spraying them? Wait until watering or just go ahead and spray them as well.

If you're spraying for mites, I think the benefit of that outweighs any potential problems with moisture around the roots. Such a small amount of liquid should dry quickly anway.

Don't know if this will help but trySt. Augustine Orchid Society - North Florida Orchid Growing,click problems and check out environmental problems. But previous responder is the go to guy.

Spoke with an individual that said she has the same thing on some of her plants and also believes this is edema. I did spray for mites as well though.

I did a quick search... here's a paper about Cstsm denticulatum. It appears to be one of the Ctsm that you never stop completely watering.

Catasetum denticulatum

There's a section from travaldo's blog, and below it a grower from OrchidForum who gets edema on some of the Ctsm he grows (click on the OrchidForum link to see article).

Maybe your Ctsm falls into that category? Just a thought. Maybe these types are more prone to edema because of the different watering? I'm just guessing based on what I read, but it makes sense.
