1. INTRODUCTION Hymenoptera organism (Kirejtshuk, 1998). The Nitidulidae are commonly known as sap Hayashi (1978) indicated that the family have feeding-beetles a large family in the been found in various habitats feeding on superfamily Cucujoidea in the suborder flowers, fruits, and decomposed fungi and polyphaga that belongs to order Coleoptera. animal tissue tissues. Abogast and Throne The family currently contains more than 4.000 (1997) studied many species of sap beetles that species classified in ten subfamilies worldwide regards as agricultural pests weather in the field or inside stored products the dusky sap (Cline et al., 2014). There are eight species of Nitidulidae recognized from the Western beetle on corn field Dobson and Erichson palaearctic region were introduced from found some species on stored maize. Dowd outside of this area (Jelinek and Audision, (1991) mentioned the damage of sap beetles 2007). A few nitidulids are predaceoucs and via either there feeding as a vector of fungi. In feed on scale or have symbiotic this family, three genera of Nitidula relationships with ants or other social (Fabricius), Omosita(Erichson) and
