I thank the member for the
question.
We certainly understand the horror
that is stable flies but we do not intend to support the release of the wasp.
The reason for this is that the trials that took place in 2015 and 2016 in a cattle
feedlot demonstrated zero efficacy for stable fly parasitism, and no scientific
literature supports this course of action.
