Question

list the characteristics of good storage for grain.

Answer 1

A food grain storage system is an artificial ecological system in which deterioration of the stored product results from interactions amongphysical (e.g. temperature, moisture, storage structure), chemical (e.g. carbon dioxide, oxygen) and biological (e.g. grain characteristics, microorganisms, insects, mites, rodents

Answer 2

In grain storage premises, when there is moderate to heavy infestation, one can observe crawling insects such as the late-stage larvae of Ephestia spp. (in search of suitable sites for pupation) and C. cephalonica, as well as adults of Triboliumspp., O. surinamensis, Sitophilus spp., and Cryptolestes spp. Furthermore, flying insects including the adults of R. dominica, T. castaneum, Plodia interpunctella, Ephestiaspp., and C. cephalonica can be observed. Careful inspection of floor areas and wall surfaces in storage premises would reveal both crawling and flying insects. Dark areas, wall cracks, and crevices are the preferred areas for insects to hide, so examination of such places could reveal the presence of insects.
