Abstract <p>About 750 million people are affected by world hunger crisis, while more than five hundred million tons of grains are destroyed annually by pests and plant diseases. Angoumois grain moth (AGM), <i>Sitotroga cerealella</i> (Olivier), is a lepidopteran stored grain pest (SGP) that can alone ravage more than 40% of the grains. Nutritional variability among host grains plays a key role in the life history of AGM. Their fitness is influenced by the balance between food intake, digestion, allocation of acquired energy, along with the genetic traits specific to the pest population and the climatic conditions. Numerous studies have recommended to evolve resistant crop cultivars for greater yield and better storage against different SGPs and to adopt control measures for the susceptible ones. However, to classify host grains and the cultivars as resistant or susceptible and to estimate the potential damage posed by this pest at a particular region, the bioecology of the moth needs to be studied on those hosts in the same context. Demographic data can then be used to project population build-ups, and predict pest outbreaks. However, management of AGM is still reliant on chemical pesticides when ecological balance has been toppled by farming malpractices over the years. Pest populations can also be effectively managed by manipulating the conditions that ensure survival of the pests in storage. Therefore, it is imperative to formulate proper Integrated Pest Management (IPM) tactics against this notorious pest that will not devastate the environment any further.</p>
