The sterile insect technique (SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild. The released insects are preferably male , as this is more cost-effective and the females may in some situations cause damage by laying eggs in the crop, or, in the case of mosquitoes ...
SIT technique may be applied as part of an area-wide control (integrated pest management) approach of insects of medical, veterinary, and agricultural importance. It was in 1937 when Edward Knipling proposed using sterilization to control or eradicate insect pests after observation that screwworm fly males mate repeatedly while females mate ...
Inherited sterility in insects is induced by substerilizing doses of ionizing radiation. When partially sterile males mate with wild females, the radiation-induced deleterious effects are inherited by the F1 generation. [1] As a result, egg hatch is reduced and the resulting offspring are both highly sterile and predominately male.
These techniques are accomplished using habitat modification, pesticide, biological-control agents, and trapping. The advantage of non-toxic methods of control is they can be used in Conservation Areas. Integrated pest management (IPM) is the use of the most environmentally appropriate method or combination of methods to control pest populations.
The proposed action, outlined in the document, uses what's known as the Incompatible Insect Technique to control. mosquito-born avian malaria. The technique consists of repeatedly releasing ...
The sterile insect technique (SIT) was developed conceptually in the 1930s and 1940s and first used in the environment in the 1950s. [7] [8] [9] SIT is a control strategy where male insects are sterilized, usually by irradiation, then released to mate with wild females. If enough males are released, the females will mate with mostly sterile ...
The sterile insect technique (SIT) is an area-wide IPM program that introduces sterile male pests into the pest population to trick females into (unsuccessful) breeding encounters, providing a form of birth control and reducing reproduction rates. [26]
Related to biological pest control is the technique of introducing sterile individuals into the native population of some organism. This technique is widely practised with insects : a large number of males sterilized by radiation are released into the environment, which proceed to compete with the native males for females.
