Plants, algae, fungus, yeast, and other creatures all contain a wide variety of biomolecules, making nature a giant "bio-laboratory." Unsurprisingly, a wide range of biomolecules and synthetic techniques may be used to create nanoparticles of different sizes and forms. The production of variously sized and shaped molecules with a variety of qualities, including safety for the environment, plants, animals, and all useful species, is sped up by naturally existing biomolecules. There are several, ecologically friendly techniques for creating nanoparticles that use a variety of substances and compounds. Vegetables, fruits, ornamental plants, field crops, insect pests, and other factors that are density-dependent reduce crop quality and productivity in nature. During the previous decade, synthetic pesticides were employed to control insect pests, but their destructive usage causes resistance, environmental pollution, pest rebound, and negative effects on people, animals, and beneficial fauna. Pesticide residues are detrimental to human health, having both lethal and many chronic effects. Worldwide, a number of countries have shifted from chemical-based agriculture to organic agriculture, which is more cost-effective, socially beneficial, and environmentally sustainable. At the moment, nanotechnology has changed agriculture, with nanotechnology-based insecticides showing the most potential for the long-term management of insect pests. The most common techniques for creating nanoparticles are physical, chemical, and many others; however, chemical techniques are once more thought to be bad for the environment and people's health. In this review article, we'll concentrate on the benefits, recent advancements, difficulties, and prospects for using nanotechnology to manage insect infestations. A number of metals, including zinc (Zn), titanium (Ti), silver (Ag), and zirconium (Zr), with varying features and attributes for the environmentally responsible control of insect pests, are used in the manufacture of nanoparticles
