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 sterile insect technique (SIT) is an environmentally friendly method for the biological control of pests using area-wide inundative release of sterile insects to reduce reproduction in a field population of the same species (IPPC, 2007).
The New World screwworm fly was the first species on which the sterile insect technique was tested and then applied in a natural environment, resulting in the control and systematic eradication of this species from North and Central America, as well as parts of the Caribbean since the 1950s.
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. Those females that ...
The F1 sterile progeny produced in the field enhance the efficacy of released partially sterile males, and improve compatibility with other pest control strategies. For example, the presence of F1 sterile progeny can be used to increase the build-up of natural enemies in the field.
There was a control group that was fed canary seeds without the ornitrol, and these birds laid almost twice as many eggs as group that was given ornitrol. It was deemed an effective chemosterilant in the study; however, after the removal of the chemosterilant from the diet, the birds were able to lay viable eggs as soon as 1–2 weeks later.
