A literature survey identified 403 primary research publications that investigated the
ecological effects of invasive alien insects and/or the mechanisms underlying these effects …

Alien invasive insects such as gypsy moth, hemlock woolly adelgid, and emerald ash borer
continue to disturb the mixed deciduous and hemlock forests of eastern North America by …

Insect herbivory during the Pennsylvanian–Permian transition interval (late Gzhelian) was
estimated from the Williamson Drive locality of north-central Texas, USA. We investigated …

It has long been hypothesized that invasive pests may be facilitated by the evolutionary
naïveté of their new hosts, but this prediction has never been examined in a phylogenetic …

1. Gregarious behaviours in phytophagous insects are common, but their adaptive value is
rarely well understood. In the present study, we document a novel case of cooperative …

Invasive, exotic insects and diseases have a devastating effect on North American forests.
The rate of spread, or range expansion, is one of the main determinants of an invasive …

Over the last two centuries, a large and increasing number of non-native phytophagous
insect species have become established in North America. In addition to the direct effects …

At least 70 exotic invertebrate pests have been newly detected in Washington State since
1990, based on records from the Washington State Department of Agriculture (WSDA) or …

Herbivores have been hypothesized to adapt locally to variation in plant defences and such
adaptation could facilitate novel associations in the context of biological invasions. Here, we …

Pyrrhalta viburni Paykull, a new landscape pest in the United States, feeds in both the larval
and adult stages on foliage of plants in the genus Viburnum. We measured lifetime …
