Aeration management strategies were developed to control cold-acclimated and
diapausing Indian meal moth larvae in grain bins in north- and east-central regions of the U.S during
winter. Contour maps showing hours below –10 oC for the months of December, January, and February were developed to help effective planning and management of aeration to control insects
that normally survive the winter. Two cumulative lethality index (CLI) models were developed to
estimate mortality of laboratory-reared (diapausing without cold-acclimation) and field-collected (coldacclimated,
and diapausing with cold-acclimation) Indian meal moth larvae under changing
temperature conditions. The CLI models were found to be useful for evaluating aeration
