Hi Mark,  
Never did try that specific combination, but bananas (fermented with beer) were uninspiring. Remember too that this mixture could be a chore to service and find flies in. Do you have any results with that? Well aged Yellow Muse or the yeast, sugar + water worked very well through the summer. Reading the translations of the original Japanese work done in 1936 and 1939 indicate good rates of capture with red wine or sake, depending on the season.

I have used apple cider with banana slices placed in a fly trap. Caught many fruit flies but no SWD. These traps were placed in winegrape vineyards near known SWD infested cherry orchards. Placement was in the month of July and August in Lodi. The concern of course was SWD infesting winegrapes but no problems in 2009. Now 2010 and we are very concerned with this years cherry crop. As you know, Cherries were infested late in the season. The battle plan is multiple sprays with malathion and or Delegate . OUCH !!!  
Any other ideas ?? HELP

Hi Mark,  
The person to speak with would be Bob Vansteenwyk at UC Berkeley who has taken the lead on SWD management in cherries. My understanding is that sprays would be initiated at first fruit color or first detected fly, but it is best to check with him or your local farm advisor to make sure.

Hi Mark,  
Does the torula + sugar + water mix use the same torula yeast tabs you pictured? Or is it a different kind of yeast?

James it's a different kind of yeast. We use the Fleischmann's baker's yeast you can get in the store. Be sure to give it some space when you ferment it, the amount of yeast plus sugar in the mix sets off a powerful fermentation process which lasts about 24 hours. After that, it is ready to be used.
