Description: "Most of the damage done by insects to grain in storage and shipments is due to four species. These are the granary weevil, the rice or black weevil, the lesser grain borer or Australian weevil, and the Angoumois grain moth. Others of the 40 species or groups of species described in this bulletin can cause great damage to grain if storage conditions are unusually favorable for their increase.... These four pests live throughout their larval life entirely within the kernel, where they feed unseen, usually unsuspected.... The other pests discussed, with few exceptions, are 'surface feeders.'" -- p. 2
