world's forests have never been more threatened by invasions of exotic
pests and pathogens, whose causes and impacts are reinforced by global
change. However, forest entomologists and pathologists have, for too
long, worked independently, used different concepts and proposed
specific management methods without recognising parallels and synergies
between their respective fields. Instead, we advocate increased
collaboration between these two scientific communities to improve the
long-term health of forests.
Our arguments are that the pathways
of entry of exotic pests and pathogens are often the same and that
insects and fungi often coexist in the same affected trees. Innovative
methods for preventing invasions, early detection and identification of
non-native species, modelling of their impact and spread and prevention
of damage by increasing the resistance of ecosystems can be shared for
the management of both pests and diseases.
We, therefore, make
recommendations to foster this convergence, proposing in particular the
development of interdisciplinary research programmes, the development of
generic tools or methods for pest and pathogen management and capacity
building for the education and training of students, managers,
decision-makers and citizens concerned with forest health.
