After half a century of service to keep Victorians safe from mosquito-borne viruses, state sentry chickens have been replaced by faster technology.
Agricultural Victoria and the Ministry of Health have developed a molecular test that directly screens mosquito samples.
It has been used to detect Ross River and Vermaforest viruses since 2019.
