    Confused About Aphids

    A sundew that had a bunch of aphids on its flower stalk was sprayed with the alcohol / water / dish soap solution. The leaves still have their dew and I don't see any aphids. Not sure if they were eradicated or if they found new homes. I sprayed a few other sundews (capensis, mostly) that had aphids. We'll see how that goes. I'm confused about aphids. I though that they laid eggs and required repeated applications of Neem Oil, over time, to kill subsequent generations. But another hobbyist tells me tha they bear live young. He was the same one to try the alcohol / water / dish soap concoction.

    Aphids are rather confusing from a reproductive standpoint. The females produce young parthenogenitically in the summer, and lay eggs in the fall.

    Another place they hide in dews is the growing point of the plant itself. I'd recommend a hand lens and checking there periodically. The babies are often small and green--I miss seeing them all the time.

    Maybe repeated applications of alcohol / water / dish soap solution will rid them, over time?

    During the growing season when all you have to deal with are the aphids themselves I'm sure it would, but I'm not sure if it would kill the eggs. You could have a resurgence in the spring. If the plants are potted, you could put the whole works in a plastic bag with some dry ice, or if your have access to a CO2 tank you could eliminate them that way. But again, not sure if it would get the eggs or not.

    How about a combination of Neem Oil when they lay eggs and alcohol when they are live bearing?
