Managing and eliminating stored product pests (SPPs) requires an understanding of their biology and behavior.

Its 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. Theyre 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.
