Sterile Insect Technique
Also written as SIT.
Sterile Insect Technique (SIT) — mass-rearing and sterilizing male vectors (via radiation), releasing them to mate with wild females, producing no viable offspring, progressively reducing population size

Practice questions on Sterile Insect Technique
The Sterile Insect Technique (SIT) controls vector populations by
- Introducing predators that eat the vectors
- Releasing sterilized males that mate unsuccessfully with wild females
- Introducing pathogens that kill vectors
- Using pheromones to confuse mating behavior
- Reduced by routine feedback control
Answer: B. SIT involves mass-rearing vectors, sterilizing males (usually with radiation), and releasing them. When sterile males mate with wild females, no offspring are produced, leading to population decline over generations. ---
