It is important to protect foodstuffs in order to avoid a fall in their commercial quality and quantity value, because the direct impact with the consumer can cause the rise of even serious health problems with consequent economic sanctions for the producer. The knowledge of pests in the food production and storage areas as well as the perfect sanitation inside the processing cycle, are both crucial conditions to achieve the proper quality of foodstuffs at their final stage. Besides some more aspects must not be neglected: monitoring harmful species which can affect the storage, preserving and processing steps (for example moths, cockroaches, mice and so on); selecting suitable, duly licensed, active principles to guarantee healthy food.
