How do you sterilize male mosquitoes?
Male mosquitoes are bred and sterilized using the same radiation found in x-rays. Males are then regularly released to mate with wild females. The resulting eggs will not hatch. In the United States, this type of SIT has been used to control Aedes aegypti mosquitoes.
How does the sterile male technique work?
The SIT involves mass breeding huge quantities of target insects in a “factory” and sterilizing the males by exposing them to low doses of radiation. These sterile male flies are then released by air over infested areas, where they mate with wild females.
Why the technique of sterile male is effective insect control?
The sterile insect technique is an environmentally-friendly insect pest control method involving the mass-rearing and sterilization, using radiation, of a target pest, followed by the systematic area-wide release of the sterile males by air over defined areas, where they mate with wild females resulting in no offspring …
What is the sterile insect release method?
The sterile insect release method (SIRM) of pest population suppression was first conceived by E. F. Knipling (1955). The method consists of releasing large numbers of sterilized insects into the environment to reduce the probability that members of a natural population of the same species will successfully reproduce.
Who is the founder of male sterile technique?
Edward F. Knipling
General Overview. The sterile insect technique harnesses the sex drive of insects. The idea of doing this first occurred in 1937 to Edward F. Knipling, an entomologist with the U.S. Department of Agriculture at Menard, Texas.
What is the process of sterilization?
Sterilization describes a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods. Disinfection describes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2).
Who is called Father of male sterility technique?
Serebrovsky
The idea of using sterile males was first written about by the Russian geneticist A.S. Serebrovsky in 1940 but the English speaking world came up with the idea independently and applied it practically around the 1950s.
What are methods of sterilization?
Sterilization can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.
What are Chemosterilants used for?
Chemosterilant, any chemical compound used to control economically destructive or disease-causing pests (usually insects) by causing temporary or permanent sterility of one or both of the sexes or preventing maturation of the young to a sexually functional adult stage.
What are 3 types of sterilization?
Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.
- Plasma Gas Sterilizers.
- Autoclaves.
- Vaporized Hydrogen Peroxide Sterilizers.
What are the 4 sterilization methods?

What is genetic male sterility?
Genic male sterility (GMS) has emerged as an ideal tool to accelerate hybrid breeding. Male sterility is generally characterized by the impairment of the male reproductive development as a result of underlying genetic causes and leads to the malformation of male gametes and/or pollen.
