In the case of early-season harvesting, there may be insects such as chinch bugs on the harvesting bins that have passed through the combine from the field and are not completely dead. This type of infestation requires no treatment, and the insects can be eliminated by passing them through a cleaner-separator. During storage, some secondary insects are possible (tribolium, silvains), but the most frequent storage problem encountered on sunflower and rapeseed is that of a possible infestation by mycophagous mites of the Acarus, Tyrophagus or Glycyphagus genera, which looks like "moving dust". These phases of mite outbreaks are linked to problems of condensation on metal containers, or to the resumption of surface humidity in seed lots, as mites can only develop if mold begins to form on the seeds. The other risk for sunflowers is that of rodents, which can get into storage cells or cold rooms to feed and thus damage the surface of containers or pierce seed bags and soil them with their droppings.
