What is genetic biocontrol?

This is a form of biological control in which genetic variants or genetically modified forms of the target species serve as controlling agents in some way, so that the threat posed by the target species is reduced or eliminated. For example, the target might be an agricultural pest species or a vector species that transmits human, animal, or plant diseases. Genetic biocontrol has the advantage of expanding the scope of target pest species beyond those for which classical biocontrol agents are available.
