Sterile insect technique (SIT) is a pest control method that uses the release of sterile insects to reduce the population of target pests, such as mosquitoes, fruit flies, and moths. The sterile insects mate with wild insects, but no offspring are produced, leading to a reduction in the insect population over time. This method is environmentally friendly and has been successfully used to control pests in agriculture, public health, and forestry. The technique requires the mass production and sterilization of insects in specialized facilities before release into the wild.
