Protecting plants from herbivorous pests is crucial for ensuring higher agricultural yields and an increased food supply for the growing population. Given concerns about pollution from toxic pesticides as well as climate change, there is a need to prioritize the development of ecologically sustainable approaches to pest management. In order to reduce the pesticide residual effect, it is crucial to develop some ecologically safe method of herbivory control. Nano-biopesticides are newer tools in pest management that target crop pests specifically and lessen the harmful effects of chemical pesticides. These novel products could be roped in for the creation of intelligent nano systems aiming to reduce unfavourable agricultural issues viz., safety, security, and high productivity. This review paper provides a comprehensive view of the evolving domain of nanotechnology in crop pest management, specifically emphasizing nano bioformulations. An examination is conducted by various researchers on the use of botanicals in crop pest management considering their sources and modes of action with their resources. Moving on to the worldwide context of nano-bioinsecticides, the advent of nano-botanical insecticides is discussed demonstrating the growing efficacy of nanotechnology in agricultural practices. The benefits of employing nanotechnology in the creation of plant-derived pesticide formulations become clear when one examines the requirements and development approaches for nano bioformulations. Various types of nano-formulations, with a special emphasis on nano-emulsions, are explored elucidating the transformative insecticidal formulations designed for targeted crop protection. Insights into the intricate mechanisms of insecticidal action through nanomaterials and nano formulations shed light on their valuable impact on beneficial insects and natural enemies. This review paper emphasized the potential of nano-bioformulation against insect pest management in a sustainable way.
