2019 Black Cutworm Pheromone Trap Report Form
Armyworm Pheromone Trap Report – 2020
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.
Pest managers, in southern Indiana, should now be scouting their alfalfa for leaf feeding from weevil larva.
Although in the Midwest the black cutworm is considered to be one of the most major pests of corn.
In looking over the black cutworm and armyworm pheromone reports, it is obvious that many moths have arrived into Indiana.
Samples to the Purdue Plant and Pest Diagnostic Lab, emailed pictures, and field visit observations confirm that corn ear caterpillars are still active in occasional fields throughout the state. With late, and staggered, planting of corn fields and the various hybrid maturities, some fields have become a “trap crop” for late-flying, egg laying moths.
For the last couple of years, especially last season, there has been a noticeable population of green stink bug in some Indiana soybean fields.
Armyworm primarily feed on grasses. As seen in the past, and now being reported this spring, they will feed on no-tilled soybean into a cereal rye cover crop.
