Parasitism of the alfalfa weevil, Hypera postica (Gyllenhal) by Bathyplectes crculionis (Thomas) was studied in 1963-66 in a 5-State area immediately east of the Rocky Mountains. The parasite was easily detected wherever weevil larvae were collected and reared. The highest rate of parasitism found was 94%. Both rate of parasitism and magnitude of weevil populations fluctuated greatly during the course of this study.
