The control of insect vectors through conventional sterile insect or trans- genic technologies (e.g., RIDL® ) is an intense focus of research in the combat against vector-borne disease. While the population dynamic implications of these control strategies are reasonably well-established, the effects of inter- specific competition between different vectors and control strategies have not previously been explored. Different control intervention methods can affect the interaction and potential coexistence of vector species. By alter- ing the shape of the zero net growth isoclines, conventional and transgenic control can affect patterns of vector coexistence and/or exclusion through Allee effects and transient dynamics. Further, transgenic control methods can mediate coexistence between target and non-target species and this can have important consequences for the persistence of disease and community ecological interactions.
