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.
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 study of managed bumble bees and honey bees on a blueberry farm finds that most of the pollen they collect comes from other plants, suggesting that supplementing crops with a diversity of nearby plant types makes for healthier bees.
Slugs are a common headache for corn and soybean growers following the conservation agriculture practices of limited tillage and frequent cover cropping. A new study finds that, among slugs' natural enemies, ground beetles provide the best control, and growers should consider practices that attract ground beetles to their fields.
What makes a non-native species "invasive"? And can a typically beneficial insect like a bee be deemed a threat to native species? Researchers explore these questions in a new review of the expansion of the non-native mason bee Osmia taurus since its U.S. arrival in 2002 and its effects on closely related native species.
