Leaf mine on Passiflora actnia, created by Spinivalva gaucha © Brito et al. (CC BY licence)

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 the conservation biology challenge of European ash dieback, the first report of Nigrospora oryzae causing stem blight on Brassica juncea in India and a new Brazilian Passiflora leafminer: Spinivalva gaucha, the first gracillariid without a sap-feeding instar.
