Many species of scale insect form mutualistic interactions with ants © Bob Peterson (CC BY-SA)

We’ve selected a few of the latest new geographic, host and species records for plant pests and diseases from CAB Abstracts. Records this fortnight include observations on the mutualism between armoured scale insects and ants, information about the Colletotrichum orbiculare species complex and the  biosecurity implications of new technology and discovery in plant virus research.
