Managing and eliminating stored product pests (SPPs) requires an understanding of their biology and behavior.
It’s also important to identify the species, to understand and predict its behavior:
- Larvae of internal feeders develop and consume within whole grains, kernels or seeds.
- External feeders’ larvae develop and consume outside whole grains, kernels or seeds. They’re also capable of feeding on whole grains and processed commodities.
- Scavengers consume grains damaged by other insects and processed commodities.
- Secondary feeders infest grain products that are out of condition or code and/or contaminated by mold and/or other microbes.
