[QUOTE="KDM, post: 495628, member: 314"] Unfortunately, no. The midges survive in the margins of sloughs and ponds as well as the shorelines and eddies of rivers. Though the changing levels of rivers helps to mitigate those particular populations. As far as control measures, there hasn't been any significant research, to my knowledge, done on large area controls for midges in say "pasture settings". Lots of stuff on controlling them on golf courses, homes, and urban to semi urban settings. BT (bacillus thuringiensis) dunks as they are commonly called, essentially slow dissolve briquets, seem to be the front runner of possible control measures in "pasture settings". However, until funding is made available to study this, it's just speculation and conjecture due to many factors. What does work. Golf course water traps are treated by tossing enough briquets into the water to cover the volume of water within. Usually in the spring with a 120 day formulation. Which means you will have lethal levels of Bt in the water for 120 days. If needed a 30 or 60 day formulation can be added if the seasonal weather requires it. Lots of studies done on this to show successful control. What needs to be done, IMO, is some studies to determine if aerial applications by helicopter to standing waters in a township sized area can control midges during the critical time frames where deer are most susceptible to infection. We did this in Afghanistan to control mosquitos and it worked great. However, no real data using scientific methods was collected as it's pretty hard to gather such data at weekly intervals when you get shot at the third time you show up in the same area. What I do know is that complaints by the troopers of mosquito bites post application by helicopter almost disappeared. Without hard data these are just anecdotal observations. It would be nice to see the gnf fund a 3-5 year study by a Doctoral candidate of Entomology, say from NDSU, to actually study this. However, it seems that throwing money at the CWD debacle is more fashionable albeit utterly useless. That's just the view from this PhD of Entomology, but what do I know? Carry On! [/QUOTE]
