Hemerocallis Gall Midge

Has anyone been bothered with this pest? I was over on the Daylily forum asking what could be possibly wrong with some of my Daylilies this year. Someone thought I might have this nasty little pest. Some of the buds were rotting or drying up and falling off, some were distorted. After talking to some others gardeners here they seem to be having the same problem.

This is the first year my daylilies have had this problem at first I thought it might be a fungal problem because of our weather this spring but now I'm thinking it might be from this Midge.

It's too late to investigate this year as all the buds that are left seem to be OK and apparently this pest is done doing damage for this year.

The only remedy mentioned is to pick all suspicious looking buds off as you see them and destroy them. I contacted The Bug Factory here to see if they had anything that might help and they said to use nematodes but to use the nematodes that are used indoors, specifically the nematode Steinernema Feltiae. Spray the foliage letting it drip down into the ground, pouring any that is left over into the soil around the plants. I don't know if this is my problem but I sprayed just in case, I'll be watching very closely next year.

This pest has apparently been in B.C. since 2001, don't know if anyone else is having this problem but thought I would bring it to everyone's attention. I think it might be better to buy bare root Daylilies rather then ones in pots and if in pots, unpot and wash the plants really well before planting as the pest hang out in the soil till they hatch the following year.

I feel like I have just rained on everyone's parade :o( but I think it's something to watch out for.
