    most of those spots look like physical damage to me not any sort of pathogen or insect damage. It could be from an insect but its definitely not viral, bacterial, or anything like that. Try Bayer Rose insecticide, that is the best thing I have used and it was recommended by our resident TF entomologist, kulamauiman

    The little white insects are in a different set of pots, ones that I have had for a few months.These insects are seen running in places where the sphag has yet to fully cover the potting mix. The little buggers could be under the live sphag as well, but I don't know if I should go dig for them..

    I was growing lots of sphagnum moss in preparation for the Wistuba plants. Now, I have too much of the stuff plus the little insects. I did treat everything with a 1 month regimen of mosquito dunks as they appeared to be fungus gnats. In retrospect, I should have brought a specimen to lab to analyze. However, the mosquito dunks did not seem to take care of the problem. Months ago, I purchased some abemectin to nuke any mite problems that might visit me in the future. It is always good to be prepared.

    The new ones from AW are the ones that arrived with the copper-brown blotches which have been slowly spreading. I emailed Andreas to ask his opinion. I am ready with the neem though. Surprisingly, the macrophylla arrived the smallest, and is the one that appears the least damaged.

    I do plant cleaning with 1:3 isopropanol every few months.

    i've had those little bugs running across the soil before. I usually repot into fresh media when i see those. I would still give the bayer rose insecticide a try.

    Just be certain that 1) the 'bugs' aren't springtails & 2) that they aren't mites if you're considering something w/ imidacloprid as the active.

    I think it would be wise to first diagnose the "problems" before treating the plants. The leaf spots look like abrasion/stress marks, which is to be expected after shipping from Germany. A certain amount of leaf stress is to be expected. On the other hand, the insects you describe sound like Springtails, which are detritivores and are, in fact, an excellent source of food for juvenile Nepenthes; I see young pitchers with Springtails inside them all the time. You may want to reconsider the need for an insecticide, if Springatils are the thing you are seeing. ID the creature first!

    They are always white and in the soil. I can tell they are colonizing when I see tiny webs in the soil. I have never seen anything black, except for a tiny worm that crawled out of a trap. As for red mites, I checked and there is nothing clinging to the underside of any leaves. I will catch some of the buggers and take pictures at lab tomorrow. This ought to be fun. If I was really serious, I would make DNA and perform some sequencing. But I already did that with my trichoderma explosion...... Hopefully the pictures will be telling. I don't want to lose any more sleep over fungus or insects.

    I could use the imidacloprid and then a follow up with the abecmetin to solve that problem.
