Populations of potato leafhopper continue to plague alfalfa fields throughout the state. Undoubtedly, the extended warm temperatures have contributed to this population explosion.
The western bean cutworm (WBC) trapping season continues, and after a slow start, moth flights have surged in many northern Indiana county traps this past week.
Japanese beetle are emerging and can be seen throughout the state on corn and soybean plants.
Pheromone trapping began for western bean cutworm moths this week. Within just one day several cooperators were reporting catches. This is just the beginning of an extended moth emergence and flight, with their peak activity expected 2-3 weeks from now.
