Insecticides are a class of chemical substances or biological products used to control or eliminate pests, including members of the organophosphates, carbamates, pyrethroids, and biological insecticides families. These chemicals or biological products achieve pest control by targeting the nervous system, muscular system, or other vital points of insect life processes, thereby blocking their lifecycle and effecting pest mortality. Insecticides are applied in various fields such as agriculture, households, and public health to effectively prevent and control the damage caused by pests. However, the use of insecticides must be cautious, as excessive or improper use may lead to environmental pollution and an increase in biotic resistance.
