Insect resistance is a research area that focuses on understanding and developing methods to control insect pests that have developed resistance to commonly used pesticides. This resistance can occur due to genetic mutations, overuse of a particular pesticide, or environmental factors. Researchers in this area study the mechanisms of resistance, develop new insecticides, and explore alternative methods such as biological control or integrated pest management to manage insect populations effectively. Insect resistance research is important for sustainable agriculture and reducing the reliance on chemical pesticides.
