Stored product pests infest foodstuff like flour, rice, oats, barley, cereals, dried fruits, cocoa, coffee, tobacco and other commodieties. ost harvest losses due to these insect pests were variously estimated at 5 – 50% in grains and non-grains. These losses could have been enough to feed millions of starving people in developing countries!

Storage is an integral part of the post harvest handling system. This is also the period most vulnerable to infestation. The quality of grains, flour and other commodities depend on a good pest control program. An entire shipment of commodity may be rejected due to some contaminated sacks!
