Pheromone Trapping Update: Armyworm Ends, Western Bean Cutworm Begins

Armyworm pheromone trapping at the Purdue Ag Centers (PACs) ends this week. Moth captures were extremely low this year, and fortunately so were larval infestations. You can see the results of the PACs efforts in the “Armyworm Pheromone Trap Report.” Their efforts are appreciated by many throughout the state!

Our pheromone trapping network has placed out their traps to begin western bean cutworm moth emergence and flights. This pest has renewed interest, especially in northern Indiana counties, as damage to fields has increased. As previously discussed in past year’s Pest&Crop, western bean cutworm has demonstrated resistance to the majority of above-ground, Bt-traited corn. Thanks to our trappers, we are now able to better time our field monitoring. More on this in future issues of the Pest&Crop.
