The adult of the soybean gall midge, a new pest in north central US soybean production, has now been verified, allowing growers to add a new photo to their "Most Wanted" list for spring scouting.
A relatively new insect in soybean, the orange gall midge has now been confirmed in 15 eastern Nebraska counties.Growers and consultants are invited to submit reports of orange gall midge in counties where it hasn't previously been identified.
Soybean aphid populations can explode in August under favorable conditions. Vigilant scouting is recommended, especially in northeast Nebraska where populations have historically been highest, to allow for timely management decisions.
Recommendations for scouting and managing soybean aphids, including why the 250-aphids-per-plant threshold is used. Two tools―an app and Excel worksheet―can help speed up scouting in the field and indicate when treatment is warranted.
Reports of orange gall midge in soybean increased in Nebraska this year and researchers have initiated in-field and laboratory studies to help learn more about its potential to reduce yield as well as best practices for its management.
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.
Part of the 2018 Crop Production Clinic Proceedings, this article reviews insects to expect in northeast Nebraska crops and links to resources on management.
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.
