Conceptual diagram about specialist insect pests
Detailed Description
A conceptual diagram of the drivers that may determine the impact of a specialist insect pest. We posit that the relationship between evolutionarily naïve host plants and invasive insect species is the strongest driver of a high-impact invasion. The diagram, modified from the synthetic invasion meta-framework described by Gurevitch et al. (2011), is guiding our USGS Powell working group’s data compilation and synthesis.

USGS Science Supports Management of Invasive Species
Invasive species can harm ecosystems, increase wildfires, damage forests, and outcompete native species. The US Geological Survey's Southwest Biological Science Center conducts research that provides our federal and state partners, cooperators and land managers with the tools, data and strategies to enhance biosecurity management.

Predicting the Next High Impact Insect Invasion
Although most introduced insects are relatively benign, some become high-impact pests causing widespread ecological and economic damage. Introduced insects that are specialists and feed on a single genus of plants can be high-impact as they can potentially eliminate an entire native plant genus over large areas. Luckily, most introduced insects with this feeding behavior do not become high-impact...
