Corn root sampling yielded the first western corn rootworm larva from north central Kansas on 3 June (fig 1). Many areas of continuous susceptible corn were sampled from fields that had significant corn rootworm adults in 2019. This was the only larva found but rootworm larvae will probably be hatching and start root feeding over the next 7-10 days.
