Biological invasions pose a growing threat to global agriculture, biodiversity, and ecosystems with invasive insect species like the Mediterranean fruit fly (medfly) among the most notorious for fruit production and trading. Effective early detection of low-density populations is essential for limiting establishment and spread, particularly under conditions that favor population growth. In this study we tried to evaluate the d...

Early detection of satellite populations is essential for managing invasive species, but traditional methods often fall short when populations are sparse and widespread. We assessed the effectiveness of terrestrial environmental DNA (eDNA) surveys for detecting spotted lanternfly ( Lycorma delicatula ) along major highways in New York State, USA, a region at the invasion front in North America. Over 2 years, we sampled 83 site...

Understanding cascading social-ecological impacts of emerging pests is key for addressing the challenges they introduce in an ever more interconnected and rapidly changing world. Here we examine shifts in news media discourse surrounding the fall armyworm invasion across Africa, Asia, and Oceania to investigate such cascades. We apply topic modeling to 570 news articles to quantify spatial and temporal changes in the prevalenc...
