Azuki​bean beetle, Callosobruchus​ chinensis (L.) (Coleoptera: Bruchidae), is a primary stored grain insect pest that infests the whole grain. It causes serious hazards and major economic losses to stored grain crops annually. To control and manage this pest, Integrated Insect Management (IPM) is used such as biological, chemical, Cultural, physical etc., but these methods fail to control such pests. Recently, nanotechnology has emerged as a promising tool for pest management due to their effectiveness and eco- friendly nature. However, in many sectors metal nanoparticles are being increasingly used, so this approach is a better option and also cost efficient and environmentally friendly approach. One of the best methods for production of green nanoparticles by using organism and plants seem to be the best option for the biosynthesis of nanoparticles which are characterized by using techniques such XRD, SEM, TEM, Zeta Potential, FTIR and UV-spectroscopy etc. Green nanoparticles of metals like Ag, Mo, Si, Fe, and other metals gave a remarkable result for controlling pulse beetles. NPs are having good characteristics like safe, energy efficient and less toxic, so these features have received great attention in recent years. NPs are less harmful for environment because NPs are safe, energy efficient and having fewer toxic routes towards environment and human health. This study is not only meant to provide an overview of the green synthesis of nanoparticles but also to present an essential view of synthesis with environmental concerns.
