Abstract:

The significance of the larger black flour beetle (LBFB), Cynaeus angustus (LeConte), as a major insect pest of farm stored grain in Minnesota was investigated during 1977 and 1980. Between 21.6 and 63.9% of the storages of farm stored shelled corn sampled were infested by LBFB. Data collected during 1980 indicated that LBFB established infestations during the first summer of storage and overwintered in storage, and that rates of infestation increased with storage time and contributed to the heating of farm-stored corn. This pest was not common or abundant in farm-stored wheat sampled.
