As the invasive spotted lanternfly continues to expand its range in the eastern U.S., a new study on the temperatures it needs for progressing through its life cycle offers a clearer picture of where the spotted lanternfly is likely to thrive—and where it’s not. In short, northern ranges and higher elevations could escape its impacts.
As the invasive Asian longhorned tick (Haemaphysalis longicornis) has spread to 19 states in the U.S. since 2017, it has become a growing threat to livestock. A new study in Tennessee takes a first look at comparing management strategies to reduce the tick's impact on cattle farms.
Identifying mealybug species is often a challenge, but the hibiscus mealybug (Nipaecoccus viridis) turns green in an alkaline solution—a unique indicator among mealybug species in Florida. Researchers have turned this discovery into a safe, accessible field diagnostic kit to aid growers and IPM pros in slowing the spread of this invasive pest.
Producing offspring from multiple fathers can add much-needed genetic diversity to populations of invasive insects, which often arise from a small number of individuals. New research confirms such multiple paternity occurs in spotted lanternflies, though to what degree it aids their spread needs further study.
A new study evaluating pesticide effects on spongy moth egg masses shows the potential value in targeting the invasive pest in its dormant wintertime stage, before hungry larvae emerge.
