What is the threshold for scouting corn rootworm beetles in soybeans during late summer?

At least 5 beetles per unbaited pherocon AM trap
A maximum of 2 beetles per trap
One beetle per 3 feet of row
Over 10 beetles per plant

The correct answer is: At least 5 beetles per unbaited pherocon AM trap

The threshold for scouting corn rootworm beetles in soybeans is established to help determine when management actions may be necessary to protect the crop. The guideline of at least 5 beetles per unbaited pherocon AM trap during late summer is key for monitoring the presence of these pests. This figure serves as an actionable level, indicating where concern for potential yield loss begins. The use of traps allows for the efficient collection and identification of beetle populations, helping growers make informed decisions based on pest density. Monitoring at this threshold level helps in forecasting potential infestations and mitigating the impact of rootworm beetles on soybean crops. By recognizing a threshold with proactive measures, farmers can reduce the risk of significant damage and improve their pest management strategies. This guideline is grounded in research and field observations, making it a critical reference for effective crop protection.
