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 ...
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 ...
Released 1600 million sterile flies in 1990. For containment method, release 60,000 sterile flies per km 2 for 12 weeks after catching the last wild fly. Field trials began in 1962. Population was suppressed strongly, but not eradicated because of long-range immigrants. Eradication was achieved in Western Australia in 1990.
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 ...
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.
Engineered Genetic Incompatibility (EGI) is a technique that is being developed to manufacture incompatibility between species in order to aid in population suppression. [18] Mimicking the Sterile Insect Technique, by introducing EGI males into a population, a sex-sorting incompatible male system is generated. [18]
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.
Biological controls are numerous. They include: conservation of natural predators or augmentation of natural predators, sterile insect technique (SIT). [26] Augmentation, inoculative release and inundative release are different methods of biological control that affect the target pest in different ways.
