Encyclopedia of Pest Management
Pests pose serious risks to crops after harvest. Rodents, mites, insects, microbes and other pests ingest food products and reduce yield sizes. They also significantly damage yield quality by leaving behind contaminating fragments such as hair, pellets, and toxins.
Some estimates attribute pests as the cause of 10% of loss worldwide and from 10%-30% of loss in the developing world. Losses can be mitigated with proper storage techniques such as using metal silos and testing air moisture content once stored.
