Illustrated identification key for Lepidoptera larvae – stored product pests regulated by countries importing Russian grain products

The article provides a key for species identification of Lepidoptera larvae – pests of grain and its processed products, regulated in countries importing Russian grain products. The work also lists those species for which this product is not the main one, and they feed, as a rule, on nuts, dried fruits, etc. The following species can be identified using this key: Cadra calidella (Guenée, 1845), Cadra cautella (Walker, 1863), Cadra figulilella (Gregson, 1871), Apomyelois ceratoniae (Zeller, 1839), Ephestia elutella (Hübner, 1796), Ephestia kuehniella Zeller, 1879, Plodia interpunctella (Hübner, [1813]), Aphomia cephalonica (Stainton, 1866), Aphomia gularis (Zeller, 1877), Pyralis farinalis (Linnaeus, 1758), Sitotroga cerealella (Olivier, 1789), Hofmannophila pseudospretella (Stainton, 1849), Endrosis sarcitrella (Linnaeus, 1758), Nemapogon granella (Linnaeus, 1758). Since the main diagnostic characters are related to the chaetotaxy features (number and position of primary setae on the body), the article presents its scheme on the example of P. interpunctella using the currently accepted setae nomenclature according to Hinton. In case of insufficient setae contrast, staining of total larvae macropreparations with carbol fuchsin is recommended. The key is illustrated with original photographs to facilitate its use by agricultural specialists and staff of quarantine phytosanitary laboratories.
