Wasps on potato stems

Has anyone else seen wasps congregating on their potato stems? I knew wasps chewed wood but not potatoes...


  • One of my cosmos plants got bent over at ground level and a wasp homed in and kept rasping away.  I suppose the stem got bruised and was leaking some nice wasp juice. I heaped soil over the spot but it died anyway.

  • I had bumble bees in my potato stems. I found 8 the other day. 

  • I went to lift a potato plant today and found the base and lower stems of the haulms were simply alive with either wasps or bees, so many that I couldn't grab the stems to lift the plant.  Does anyone know whether they will disappear of their own accord, or damage the tubers?  Can I safely get rid of them without damaging the crop?

    Wish I just had to deal with Bees/Wasps

    I am plagued with rabbits!

    I grow my pots under plastic sheeting with just a small hole in the sheet to insert the potato but they just dig them up and start gnawing on the potato.

    I wouldn't mind if they just kept to one or two plants but, they annoyingly go from plant to plant digging up big amounts of my crop!

    I have 210 plants and they (the rabbits are a constant headache)image
