Summary

A STUDY WAS CONDUCTED IN KANSAS TO EVALUATE THE IMPACT OF AIRFLOW RATES HIGHER THAN 0.02 M3/S.M3 FOR AERATING WHEAT IN 6.4 M DIAMETER BINS DURING WARM MONTHS. A 10 K DIFFERENCE BETWEEN AVERAGE AMBIENT AIR TEMPERATURE AND INITIAL WHEAT TEMPERATURE JUSTIFIED A COOLING CYCLE. HIGH AIRFLOWRATES COOLED THE WHEAT BY AN AVERAGE OF 6 K WITH ABOUT 9 H OF FAN OPERATION. DATA FROM THE LITERATURE WERE USED TO SHOW SUCH A REDUCTION IN GRAIN TEMPERATURE COULD REDUCE INSECT POPULATION GROWTH BY 80-97%. AIRFLOW RATES HIGHER THAN 0.02 M3/S.M3 WOULD ALLOW TO UTILIZE THE LIMITED HOURS IN JULY AND AUGUST WHEN AMBIENT AIR TEMPERATURES ARE BELOW 293 K (20 DEG C) OR 10 K BELOW HARVEST TEMPERATURE.
