de determi- nation of moisture content, bulk density, germination tests (glutamic acid decarboxylaseactivity or tetrazolium tests), amylase activity (Hegberge test), free fatty acids, nonreduc-ing sugar contents, detection of insect infestation, and mold counts. Indices of fungal loadcan also be assessed by chitin and ergosterol assays. These details will help assess the shelf life potential of the grain; hence, assessment of grain quality is an important storage strategy (. Among the quality parameters the water activity or moisture content of the grain is the most signicant because it has an inuential effect on the multiplication of insect pests and growth of other spoilage organisms. The moisture content will not be uniform in bulk storage and is likely to vary between farms, between truck loads or grain lots, and in bag storage between peripheral and inner bags, and in bulk storage betweentop layer and periphery or in depth. The highest moisture prevailing in any part of thegrain bulk has more practical importance than the average moisture content. 1.3.2 Physical Factors Because pest activity is dependent on temperature, the latter plays an important role during grain storage. The optimum temperatures for the growth and multiplication of insects,fungi, and mites in stored grains are 2, 3, and 2 , respectively. Development of insects and mites is decreased, respectively, at temperatures less than 1 and 5C. The mold growth, however, is affected only at 0 or below. As the temperature rises, the rate of respiration of the grain and the pests in it increases. Furthermore, the enzymaticactivity of grains goes up. This enhanced biological activity leads to rapid quality deterio-ration at higher temperatures. Another interrelated factor is the moisture or water activityof the grain. Moisture content in the range of 1% is favorable for insect development.When the water activity is 0.9 or more, mold and other microorganisms thrive. When thewater activity is low, the pe
