This document discusses using nanotechnology for pest control, specifically using silica nanoparticles as a potential new insecticide for controlling the cotton leaf worm, Spodoptera littoralis. It notes that this would represent the first use of nanotechnology in agriculture. The authors are from Egypt and study plant protection and economic entomology. They propose testing silica nanoparticles against S. littoralis and assessing its potential as a new insecticide for cotton pest control.
