Summer insect activity - Corn rootworms, click beetles, and bean leaf beetles
This article discusses some of the current insect activity in summer row crops in portions of Kansas. Each insect is discussed and is accompanied by photos.
Soil temperature impacts on western corn rootworm eggs
The recent Arctic-like weather raises some questions about insect pressure for the upcoming growing season, particularly for the western corn rootworm. Will this severe cold snap kill eggs that are currently lying dormant in the field?
Estimating western corn rootworm egg hatch and adult emergence
Degree-day models are useful tools for estimating the development of different insects, allowing us to predict when potential pests might begin to impact a crop. For the Western Corn Rootworm, degree-day calculations can be used to determine the onset of egg hatch in an area, peak egg hatch, and the timing of adult emergence.
