Abstract: Trogoderma granarium Everts (Khapra beetle) a serious pest of stored grains and stored products with quarantine status is one of invasive species feared around the world. Detection of Khapra beetle live or dead attracts serious trade restrictions and economic fallout, especially in developing countries like India. It attracts strict phytosanitary regulation by many countries in order to restrict the pest at the boundaries. The pest is difficult to control owing to its diapause. It is, therefore, necessary to design a system’s approach to tackle this pest. However, to design such a system, precision knowledge regarding identification, biology and reproductive system is essential. Determination of larval instars according to Dyar’s law helps to identify this pest in infected samples. Identification of adult khapra beetle on the basis of morphology is difficult due to its similarity with other dermestids, thus study of genitalia will specify the species and also aim in understanding its reproduction and fecundity.
