Controlled Aeration During Rice Storage: Effects of Geographic Location on Insect SurvivalPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 026125, 2002 ASAE Annual Meeting .

Gardisser Keywords: Rice, storage, controlled aeration, insects, temperature profiles Alternative storage strategies in grains are critical in combating insect problems, especially with many traditional chemicals being threatened for reduction. This work examined the use of controlled ambient aeration to reduce the temperature and to inhibit insect populations in stored rice at three geographically different locations in Arkansas. Cypress rice at a northeast (NE) and central (CEN) storage location and cv. cocodrie at a southeast (SE) location were stored for one season. Half of the bins at each site were aerated traditionally, and the remaining bins were aerated with a thermostatically-activated controller to reduce the temperatures within the bins. Insects, in cages, were placed in each bin, and the cages were sampled periodically to determine their viability. The ambient conditions available for aeration control were not significantly different from one another. Temperatures within the bins aerated by the controller were not significantly lower than those in manually-aerated bins. Live insects recovered at each sampling time were reduced with storage duration, and fewer were recovered from the SE location (most likely due to cultivar). Total recovered insects, after the rice from each cage was allowed to incubate, were reduced with the aeration controller in addition to the previously mentioned parameters.
