Little green worms eating my roses

tarisaline(4)November 8, 2007

This is the third year that my roses have been defoliated! I have tried everything short of explosives and I need help. These worms range from barely visible to a half inch long and are a bright green. Anyone have any suggestions????

Are they about a cm long growing to about an inch long? If they are I had them on my roses this summer too. I don't know what they are called but they put lots of holes in leaf and flower. I hand-picked them off along with the Japanese beetles. I also happened to have rust, mildew,black spot and a lot of aphids all at the same time. I used a Safer's 3 in 1 pesticide, fungicide and (???icide) and in about two weeks the roses were very happy and very healthy. I don't know of any organic controls for the worms. Seems the season is nearly over so maybe mother nature will take care of your problem. Zone 4 has got to be cold by now.
Cheers,
Tyler.

I think they're called sawfly larvae, and there's probably some spray you could use (they're soft bodied so maybe insectidal soap would work?)...but I always just spend a day in spring, picking the darn things off the rosebuds & squishing them dead while muttering imprecations, lol. Works for me!

they sound like the same little green worms that i have on my westeria plants, they bed themselves between to leafs and feed on the leaf.. and get big and fat.. about an inch i'd say.. they are a bright green with black heads... there are also wasp and or hornets searching for these little green critters... once the bee gets ahold of it it bites it head off and eats the body... I couldn't believe this when my husband told me what they were doing until he showed me. I was swating the bees away, but now that I know what they are doing on my plants I just let the bees take care of the worms... strange as it sounds...
