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.
When was sterile insect technique developed?
1930s
Development of the sterile insect technique. The idea that populations of economically important insect species might be controlled, managed or eradicated through genetic manipulation was conceived in the late 1930s by an American entomologist, Dr Edward F. Knipling.
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.
What is one disadvantage of sterile insect technique?
The Downsides to SIT One issue is that, for some pests there is no cheap, fast, or effective way to sort through the pests in a large number, and determine whether they are male or female. Another issue is that the amount of radiation used to sterilize the insects, is too damaging to the insects will just die.
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.
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 …
How are male mosquitoes sterilized?
What is sterile male insect?
It is most simply described as a form of insect birth control that is carried out on an area-wide basis. These sterile male flies are then released by air over infested areas, where they mate with wild females. If the sterile males vastly outnumber the fertile wild males, the wild fly population quickly dies out.
What are male mosquitoes?
The focus of the male mosquito life is to find water, food, shelter and a mate. They feed mainly on water and plant nectar. Male mosquitoes have no need for animal blood like the females, so they generally avoid contact with humans. Male vs. Female Mosquito Buzzing.
Which is true about the sterile male technique?
Definition and principles; The Sterile Insect Technique (SIT) (or sterile male technique) is an autocidal insect control method. It is a species-specific genetic “birth control” method that is inversely density-dependent, becoming more effective as the size of the target population decreases.
Is there a way to sterilize male mosquitoes?
A technique that sterilizes male mosquitoes using radiation will soon be tested as part of global health efforts to control diseases such as chikungunya, dengue, and Zika. The Sterile Insect Technique (SIT) is a form of insect birth control.
How does the sterile insect technique ( SIT ) work?
The Sterile Insect Technique (SIT) is a form of insect birth control. The process involves rearing large quantities of sterilized male mosquitoes in dedicated facilities, and then releasing them to mate with females in the wild. As they do not produce any offspring, the insect population declines over time.
Why are males more efficient carriers of sterility?
Males are more efficient carriers of the sterility trait, as they often copulate more than once, whereas females may be restricted in the number of their matings. When only males are released, assortative mating amongst the laboratory-reared insects can be avoided, increasing the exploitation of the sterile sperm.
