    Default What pest is eating OLD growth? PB vampire

    I was helping a friend get plants ready for winter and noticed a weird problem with several Onc. intergenerics. I didn't get a picture, but it looked like some critter had punched a small hole (about 0.5 cm) in the bottom of mature pseudobulbs and mined out the flesh inside. What was left was a green pb shell with a few fibers inside. The color looked off, and when you touched the still plump-looking pseudobulbs they would colapse on empty space.

    The weirdest part about it is most of these orchids had lots of healthy new growths that were completely untouched. I always thought pests went for the tender new shoots first.

    So who is the pseudobulb sucker?

    Possbile suspects:

    Snails--saw lots of those tiny snails

    Centipedes--the orchids close to the cacti seemed to have more of these

    Slugs--only saw a few of these, enjoyed watching them shrivel under alcohol spray

    Pill bugs (aka woodlice) --would these feed on live plants?

    orchid sucking nocturnal vampire bats?

    Could it be an ant?? Many orchids are "homes" for ants. The previously named Schomburgkia, now called "Myrmecophila", have hollow p-bulbs that ants live in. Just a thought....

    I would agree with Connie. Look online for some specific ant species, and also just keep an eye on the plants pbulbs for any activity. That might give you a clue. Centipedes are carnivores, so it isnt them, Slugs are too large, and always in my experience, go for the tender new shoots, same with snails, Woodlice feed off the fungi that starts to grow in old wood, and as for the orchid sucking nocturnal vampire bats, THATS JUST AWESOME!

    Ha, Ha Jordan. I didn't actually lay eyes on those bats.

    I didn't see ANY ants. We have had a few weeks of much cooler weather, maybe they've gone. . . whereever ants go when it gets cold. I don't think my friend has any myrmecophiliae. If I had to guess at a common thread in the sucked-dry orchids it would be odontoglossum--beallara, miltonidium, colm, vuyl, wils.

    Thinking about it, there were piles of weird ground up substance under some of the trays. I thought it might be rotting benches, but it did have that weird uniformity that you see in anthills.

    My friend is not fond of heavy chemicals beyond rubbing alcohol, dish soap and cheap beer (hence the long list of suspects above). Any ideas for effective natural ant control?

    sounds like ants to me, i know here we have 3 species, black, argentine and a red varient of the black, but perhaps the ants eating yours are a tiny iddy-bitty species? Maybe they have migrated for the winter?
