Every spring, voluteers throughout the state put forth considerable effort in trapping for the arrival and intensity of black cutworm moths. We are indebted to these faithful bug counters, hoping you also appreciate their efforts as reported in the “Black Cutworm Adult Pheromone Trap Report.” If you recognize a name or two on this list of volunteers, by county, please thank them for their efforts! Heck…buy them a cup of coffee! Not since 2012 have we seen such an early flush of black cutworm moths! As described in a Pest&Crop #3 article, an intense storm causing lives and destruction on April 1, also brought massive numbers of moths from the Southwestern States. In addition, we’ve not had widespread freezes since then. Because of that, we set that date as biofix, and began accumulating heat units for cutworm development, that also tracks very closely to corn development. This is all explained[Read More…]

Once again, we urge you to view the “Black Cutworm Pheromone Trap Report.” For the fifth consecutive week, our volunteer trappers have been busy counting captured moths, e.g., lots of intensive captures.
Many factors (many of them unpredictable) determine an insect outbreak.
The storms’ origins in the Southwestern U.S. literally vacuumed up black cutworm moths and “spit them out” during its passage through the Midwest.
As the soybean crop begins to mature and the plants “shut down”, many insects are no longer interested in these plants.
Fall armyworm pheromone trap catches low throughout Indiana.
In recent weeks, fall armyworm infestations have been decimating some soybean and forage crops in Kentucky.
Although some other states in the US corn belt, and in Ontario, Canada are seeing high moth flights (and we thought Indiana would follow suit), Indiana is a “have-not” state for WBC this year.
Everyone remembers last year; many are awaiting this year’s fall armyworm (FAW) attack. Still, at this time, there is little activity reported in the Midwest.
Although some other states in the US corn belt, and in Ontario, Canada are seeing higher moth flights, Indiana, like last year, is a “have-not” state for WBC this year.
