Sterile Insect Technique (SIT) is a process by which sterile male pests are introduced into the pest population to trick females into unsuccessful breeding encounters, providing a form of birth control and reducing reproduction rates.
Gene transfer techniques can help produce modified plants which have been pre loaded with target-specific toxins, which will be toxic to only the targeted pest and no other form of life. B Gene introduced into the cotton plant to combat the cotton bollworm is one such example.
Natural pesticides are naturally occurring compounds from plants, animals, fungi and bacteria, which can act as pesticides. Many serve as repellents whereas some are toxic, though only to a narrow range of related pest species. Examples include citronella oil, garlic oil, neem oil, pongamia oil etc.
