New tech targets crazy ant invaders
James Cook University researchers will use a high-tech, ground-breaking technique to try to solve the expensive problem of yellow crazy ant (YCA) infestations.
JCU’s Dr Cecilia Villacorta Rath and Dr Lori Lach will investigate using environmental DNA (eDNA) techniques to track yellow crazy ant invasions in a three-year project, thanks to funding from the Australian Government Department of Agriculture, Water and the Environment.
Dr Villacorta Rath said invasive invertebrates are estimated to cost agricultural production $4.7 billion annually, and up to $8 billion, considering all impacts and expenses.
“YCA colonies can reach such large population numbers that properties can become unliveable, unprofitable and unsellable as ants invade. YCA also pose a threat to the environment by removing biodiversity as they spread. The impact of the incursion of YCA in Cairns alone will exceed $700 million over the next seven years if not contr
