Scouting and Treatment Recommendations for Western Bean Cutworm
July 12, 2024
Scouting should be prioritized in fields that are at the preferred growth stage for egg-laying and/or do not have the VIP3A Bt trait to protect them from western bean cutworm injury.
Western Bean Cutworm Flight Predictions for 2020
June 17, 2020
The growth stage of corn during WBC flight is critical as moths prefer to lay their eggs on corn plants between the late whorl to early tassel stage. Survival of young WBC larvae is highest if they can feed on newly emerged tassel prior to moving into the ears.
Spring Miller Moth Invasion
May 26, 2020
During the daylight hours the army cutworm moths seek shelter in cracks and crevices including those found in houses and other buildings. The moths begin to emerge from these locations at dusk to resume their feeding and westward migration.
Scouting Advised for Alfalfa Weevil
May 6, 2020
Alfalfa weevils have been reported damaging alfalfa in north central Kansas. As temperatures warm up, expect to see alfalfa weevil larvae in southern Nebraska and slightly later, in northern Nebraska.
Army Cutworm Scouting Urged in Western Nebraska Wheat and Alfalfa
March 27, 2020
Army cutworms have been spotted in Kansas and Nebraska crop fields this month. This is an important time to scout for this pest, particularly in wheat and alfalfa.
Advances in Understanding the Management of the Wheat Stem Sawfly
January 28, 2020
Over the past few decades, WSS populations have greatly increased and expanded in the Nebraska Panhandle, becoming the most economically significant pest of wheat.
Novel Strategies for the Management of the Western Bean Cutworm
January 22, 2020
The western bean cutworm is a pest of corn and dry bean. Typically, control is achieved by pyrethroids or transgenic traits. However, control with pyrethroids may prove difficult and transgenic traits are not available for dry bean. Biological control may prove to be a useful tool for growers of both crops.
Management Decisions Impact Wheat Stem Sawfly Populations
August 30, 2019
University research in the Nebraska Panhandle suggests that changing two management strategies may help significantly reduce wheat stem sawfly pressure in winter wheat. Over the years, the sawfly has become a major pest in wheat with few known control measures.
