Storage structures at public level: The government has constructed large sheds commonly called house type godowns constructed with some variations to suit climatic and other conditions of the area. Temperature and moisture are most important factors as these not only affect the quality, but also give rise to insect pests and fungi. The optimum temperature for most insect pests is around 28-32°c. They are able to develop and multiply between 15.5 to 18.3°c. Many can live long at low temperatures but their activity is reduced very much. These feed on dry materials need certain amount of moisture.
