Storm systems from the Southwestern portions of the country have brought more than rain showers. Many of our pheromone trap cooperators captured black cutworm moths over the last week…though numbers are relatively low. Most surprising was the number of armyworm moths captured in East Central Indiana at the Purdue Davis Ag Research Center.

The western bean cutworm (WBC) trapping season continues, and after a slow start, moth flights have rapidly increased in many northern Indiana county traps the past two weeks. With warm temperatures, egg development and hatch will happen within about 6-8 days after they are first placed by females. This will give little time for egg scouting. Unfortunately larval scouting is far more difficult, time-consuming and less reliable. In other words, some larvae have hatched and have already infested corn whorls, leaf axils, and/or ears. Control is very difficult at this point and those just looking for egg masses beginning now will likely be underestimating the population. However, it’s not too late! Although some eggs have hatched, our current period of increased moth activity represents the peak for egg-laying, as the vast majority of WBC eggs will be laid over the next 2 weeks.

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.
The “notched leaf edge” symptom in corn is a curious genetic leaf “disorder” that appears in certain hybrid families during periods of rapid development.
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.

Though black cutworm and/or armyworms moths may be present in the state, they are certainly hanging low until the conditions improve.
