Aphids?

20 years ago

All of the talk about aphids in another thread got me looking more carefully at my plants. I noticed that one of my favorite plants (a lawn of spatula-leaf sundews with 20+ flower stalks) looks like it is infested with small white dots. They are all over some of the leaves, and they are a quarter of the way up some of the flower stalks. It is a pretty dewy sundew, and in many cases, the plant may have won the battle. I don't see any misshapen leaves or other obvious problems. But there are so many of the white dots.

With a strong magnifying glass, they appear to be sort of football shape, and I think I can see legs. Do these sound like mealy bugs, aphids, or something else?

I assume I need to isolate the plant from my others.

Would anyone recommend submerging the whole plant (pot, soil, sundew leaves, foot-long flower stalks and all) in dehumidifier water for a day? I'd rather avoid orthene if I can, because I'm worried about the effect of insecticide on this great plant.

I had also hoped to harvest seeds at some point.

Appreciate any advice.

    if you say that the small dots are white, then they might be mealy bugs. i never had these before in my plants. aphids are usually tiny green little bugs and their legs are quite visible, they come in clusters of 10s sometimes.
    (i hate those things)

    do you see any leaves bitten off? or are they just the base leaves? are the leaves with the dew infested as well? sundews hardly ever face bug problems since they can fight back by sticking the bugs on their dewy leaves. i wouldn't summerge the pot. it would be a bit trickier than any other cp.

    like you said, you may isolate the plant away from your other plants. If i had a sundew facing bug problems(which inever had) i would just move its growing location. maybe trimming some of the old base/bottom dead leaves as well. usually when i see aphids(not often) on my plants, i get the bugs with a small stick and feed the bastards to my sundews haha~ if i were you, the only insecticide is the dews on the plant. gather the bugs with some type of stick or whatever.. then place the bugs on the dewy leaves, it can be fun since they destroy mother nature. whatever you do, be careful

    Just a thought but it could well be aphids. They leave shedded skins everywhere which look exactly like you described. If I were you, I wouldn't do anything yet but wait to see if any malformed leaves develop.

    They could have been aphids which shedded their skins then got caught by the sundew before they could lay eggs. If this is the case then your all clear but just keep an eye on new growth for a while.

    It would be beneficial if you could post a macro photo of these things.

    Kyle,

    The idea of shed aphid skins sound very believable. They certainly don't move at all. But there are hundreds of them. Would that be expected?

    I haven't gotten myself into digital macro-photography yet, so it will not be easy to post a picture.

    Thanks.

    If there are literally hundreds of them, that sounds a bit excessive. Try scraping a few off with something - do they just scrape off easily or are they firmly attached? Also, are there any marks left on the plant once you have removed a few?

    This is probably a naive question. With all of the flower shoots (>20), I don't suppose there is any chance that they are white seeds that dropped out, is there?
