Abstract

A field study was conducted in 1996 and 1997 to determine survival and spatial patterns of alfalfa weevil, Hypera postica (Gyllenhal), larvae within and between windrows of swathed alfalfa, Medicago sativa L., forage as dry matter concentration increased. After harvest, the percentage of live weevil larvae residing in swathed forage decreased as swath dry matter percentage increased. Conversely, larval populations in stubble between windrows increased with increasing swath dry matter. Larval populations in stubble under windrowed forage increased slightly as windrowed forage dry matter increased. Applications of these results for the development of alfalfa harvest systems for improved cultural control of alfalfa weevil are discussed.
