Alfalfa Weevil Resistance to Pyrethroids

from Pasture and Forage Minute · host University of Nebraska - Lincoln

Alfalfa weevil is a serious pest of alfalfa and can cause significant damage, usually in April and May before the first cutting. Reports of reduced efficacy of pyrethroids in Nebraska as well as confirmed resistance to pyrethroids in several western states led to a project in 2025 to determine if Nebraska weevil populations are developing resistance.
