Hey boss, can you fill us in a bit more on the pherocon deal for this fly? I haven't tried it, but if it is more efficacious on trapping than yeast sugar water or apple cider vinegar, I'd be very interested in knowing that.

Hi Mark,  
I haven't tested the recent one, but an earlier version worked well. Apple cider vinegar and yeast-sugar solution also work, but there are several reports with conflicting results on which one is more attractive. Type of the trap could also contribute to this variation.  
Thank you,

Ok thanks Surendra. Not to get deeper into the weeds than need be, but we found in work with Hamby, Sheehan and Zalom that the apple cider vinegar worked better than yeast sugar water in the winter, while the converse was true in the summer.  
Definitely agree that trap type is going to contribute to the variation, so we'd have to control for that in a study.  
If you do happen into those pherocon deals, maybe send some up to me for a side by side with our traditional trapping media.  
Thanks for putting this out - I read your blogs pretty closely.

Yes, Mark! It all depends on the crops, attractant mixes, traps and so on. That is why I did not make specific recommendations, but provided available options.  
Thank you for asking these questions as it will add clarity.
