Pest outbreaks are among the major factors that affect agroecosystems, subsequently leading to the excessive use of fertilizers and toxic pesticides, polluting the environment and causing serious health concerns. This indiscriminate use of conventional pest-controlling chemicals has led to the development of pesticide resistance, affecting soil fertility. Ultimately, there is a need to find alternative means to manage pest situations. In this regard, nanotechnology has emerged as a novel technique with a wide range of applications in agrochemical and Phyto-protection systems to control pests to a significant extent. Nanoparticles are being used in different nanoformulations of pesticides, insecticides, and nanobiopesticides with broad-spectrum biopesticidal potential, which could be fabricated by using various metals like silver, zinc, alumina, copper, gold, and titanium. However, further research is required to understand the interaction between the metals and the natural biopolymers needed for their reduction during nanoparticle formulation. Keeping in view the importance of the issue, the current review encompasses a detailed discussion of pest-related issues including crop losses and their global impact followed by the mechanism of pesticide resistance and demand for biopesticides. Furthermore, the role of nanobiopesticides in pest control has been highlighted briefly with their mode of action.
