Pest categorisation of Popillia quadriguttata

EFSA Journal, Volume 22, Issue 6, June 2024.
Abstract The EFSA Panel on Plant Health performed a pest categorisation of Popillia quadriguttata (Coleoptera: Scarabaeidae), following a commodity risk assessment of bonsai Pinus parviflora grafted onto P. thunbergii from China, in which P. quadriguttata was identified as a pest of possible concern for the territory of the European Union.

Native herbivore browsing alters plant physical and chemical traits in a eucalypt forest understory

Ecosphere, Volume 15, Issue 1, January 2024.
Abstract Macropods exhibit selective herbivory on plant traits within and between species and hence can alter plant trait variation. In this study, we asked what are the effects of macropod herbivory on intraspecific variation in plant traits of forest understory species?
