The tiny discovery with big biosecurity benefits

Plant Biosecurity CRC researchers based at Agriculture Victoria’s AgriBio, Centre for AgriBiosciences, have discovered a new bacterium, a novel candidate species of Liberibacter, inside a native Australian eggplant psyllid, Acizzia solanicola. Its discovery can help ensure diagnostic tests do not give false results for destructive diseases associated with other types of psyllids. The benefits for industry are potentially significant, as false results can be highly damaging for trade.

Psyllids are tiny insects that can spread bacteria that cause devastating plant diseases, such as zebra chip disease in potatoes and citrus greening – diseases that are not yet present in Australia.
