Ecological research conducted over the past five decades has shown that increasing tree
species richness at forest stands can improve tree resistance to insect pest damage …

International trade and movement of people are largely responsible for increasing numbers
of non-native insect introductions to new environments. For forest insects, trade in live plants …

Forests are critical habitats for biodiversity and they are also essential for the provision of a
wide range of ecosystem services that are important to human well-being. There is …

While the regional distribution of non-native species is increasingly well documented for
some taxa, global analyses of non-native species in local assemblages are still missing …

The economic and environmental threats posed by non-native forest insects are ever
increasing with the continuing globalization of trade and travel; thus, the need for mitigation …

As part of national biosecurity programs, cargo imports, passenger baggage, and
international mail are inspected at ports of entry to verify compliance with phytosanitary …

Worldwide, forests are increasingly affected by nonnative insects and diseases, some of
which cause substantial tree mortality. Forests in the United States have been invaded by a …

Biosecurity surveillance has been highlighted as a key activity to discover non-native
species at the initial stage of invasion. It provides an opportunity for rapidly initiating …
