Methods of disease eradication include vector eradication.&lt;ref name="Chapter 6Could we/should we eradicate mosquitoes?"&gt;2021. Nancy Leys Stepan. . . Chapter 6 Could we/should we eradicate mosquitoes?&lt;/ref&gt; Vectors to be eradicated very frequently include mosquitoes. In 1944 Sardinia had 4 native mosquito species. In 1944 the Italian government and the Rockefeller Foundation initiated and funded a programme. This programme attempted to eradicate Sardinia's mosquitoes. This programme succeeded in eradicating 3 of these species. This programme eradicated by using large amounts of DDT. The results of this programme teach us about what vector eradication does to the environment. Some experts believe this teaches us that vector eradication is not necessarily disastrous. They believe this because eradicating Sardinia's mosquitoes has not produced any ecological consequences.
