GF-120® NF Naturalyte® Fruit Fly Bait or Home Made Fruit Fly Bait

[anon89542713]

Does anybody know a source of this in small quantities? All I can find is just one site that sells 13lb bottles for $193. Last year I lost all my currants and gooseberries to currant fruit fly. With exceptionally mild winter this year I am sure they will be back. So I am looking for solution. I probably can cover currants and tie the cover on the trunk, so flies that emerge from soil are not trapped inside the cover. But I do not see it possible for gooseberries, and I think I need to spray. I know Spinosad mixed with Fruit Fly Bait should work as spot application on the branches. But only Fruit Fly Bait I can find is the one above. If this one is not sold in smaller quantities, is there a way to do your own bait and mix with spinosad? Anybody have a recipe?

Check out this link. Also you could use floating row covers to cover plants.

Attract and Kill- SWD

There has been promising research to reduce the population and egg laying of spotted wing drosophila using attract and kill stations, they are hung in fruit rows and sprayed weekly with a mixture or raspberry concentrate, apple cider vinegar, yeast and a pesticide for adults to feed on. It is important that the attractant stations are round shaped and red colored to visually attract SWD. The most current construction Mr. Jentsch is using is a mesh disc which is coated in super absorbent polymer…

Yes, I am planing to use covers on currants, but to do it on gooseberries is almost impossible. If I try to cover bush without frame, the cover will stick on the very spiky brunches an I will not be able to tie the bottom around trunk without loosing some blood. And if I use the frame then whatever pests are already in the ground - they will hutch under the cover, to make it useless. I was thinking about using apple or raspberry vinegar, but whatever source I could find says “protein bait” and I am not sure what it is.

“protein bait” and I am not sure what it is.

I don’t know for sure but I think the protein may be covered by the yeast- which is, indeed, protein.

Thanks!

Sorry not sorry for the resurrection, I believe forums such as this have immeasurable value as a reference.

As such as I am researching effective and organic fruit fly control I was led to this thread.

It seems the protein source is indeed yeast, and in particular Torula yeast is used as an attractant, often with perhaps sugar in some form(most likely molasses) and spinosad.
This mixture seems to be quite effective in many countries for a variety of “fruit fly” species.

This is related to but not directly answering OP’s question.
I hope others find this useful.
