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.

A few soybean fields were planted early, and they are not only emerged, but well into the V-growth stages. Producers are just now finding that these “islands” of legumes have become a trap-crop for bean leaf beetle activity early this season.
The nematology laboratory at Purdue University will be closing at the end of June. The last day we accept samples is the first of June.
