Scouting and Treating Western Bean Cutworm
July 11, 2018
Western bean cutworm egg masses have been reported on field corn in a number of locations across the state this week. Here's what to look for in the field, treatment thresholds and recommendations.
Insects in Cover Crops
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics on how integration of cover crops in cropping systems will alter pest and beneficial insect activity.
Using Degree-Day Models to Predict Western Bean Cutworm Flights
June 21, 2018
By using a degree-day model, growers can account for the effect of temperature on insect development and approximate when certain insect stages will occur. See predicted cutworm flights and recommended scouting periods for 14 Nebraska locations.
Wheat Insect Pest Update
January 8, 2018
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics reviewing the status of insects in wheat, particularly the wheat stem sawfly.
Large Populations of Painted Lady Butterflies
January 8, 2018
In 2017 large populations of painted lady butterflies were seen across the state, raising concerns about whether the larvae form (thistle caterpillars) of this insect would cause damage to soybean fields. An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics.
Wheat Stem Sawfly Numbers Up in the Panhandle
June 6, 2018
Video: Populations of wheat stem sawflies, a serious pest of wheat in western Nebraska, are at high numbers this year. Surveys are underway in wheat fields, grasslands and pastures to evaluate grass hosts for the pest and its parasitoids.
Scout Diligently for Alfalfa Weevils in May And June
May 16, 2018
High populations of alfalfa weevils have been found in alfalfa throughout the Nebraska Panhandle; lower populations were reported this week in central and eastern Nebraska. The economics would warrant continued scouting through June to provide for timely treatment, if necessary, and yield protection.
Corn Rootworm Management Update
January 8, 2018
From the 2018 Crop Production Clinic Proceedings: Corn rootworm continues to be a problem for Nebraska growers who rotate crops infrequently. Additionally, resistance to insecticides and some Bt corn reduces efficacy of these important tools in some fields.
