Nanotechnology holds great promise for controlling insect pests by using controlled and targeted delivery of agrochemicals. As insecticides and insect repellents, nanoparticles, nano emulsions, nano suspensions, and nano capsules have a wide variety of uses. There have been studies on stored grain insects (Tribolium castaneum, Callosobruchus maculatus, Martianus dermestoides, Rhyzopertha dominica, Sitophilus oryzae, Corcyra cephalonica, etc.), crop pests (Aphis nerii. Spodoptera litura, Bactrocera dorsalis etc.) and other pests in this regard. Nanoencapsulation is the most promising technology for crop protection at the moment. Nanotechnology can revolutionize insect pest management in the future.
