Black cutworm trap report table
Black cutworm trap report table
The Japanese beetle (Popillia japonica) was taken in government bait traps in Indianapolis for the first time.
This week, I was contacted about a 300+ acre, 5-6 leaf cornfield with multiple problems, described as plants dying and toppling over with feeding damage at the base of the roots.
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 many have asked, or made note, insect pest numbers seem lower this season. No surprise that the moisture and temperature extremes have had an impact, especially those insects depending on the soil to complete at least a portion of their life cycle.
In looking over the black cutworm pheromone trap reports, it is obvious that many moths have arrived into areas of Indiana.
It seems that the freezing temperatures, and snow, of just over a week ago has spurred an increase in the black cutworm and armyworm moth activity, see the accompanying pheromone trap captures.
Weather systems originating in the south will often carry insects north with them.
Many black cutworm trappers have captured large numbers of moths, see “Black Cutworm Pheromone Trap Report.” In trying to find levity during the Covid-19 pandemic, there have been various quips during their reports about this pest’s lack of adherence to our social distancing guidelines!
Last week’s articles were concerning the eye-popping numbers of black cutworm and armyworm moths being captured by pheromone trap cooperators and weevil damage being reported in southern Indiana alfalfa fields.
