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.
In a new lab study, spotted lanternflies moved toward the source of a nearby 60-hertz vibration. Further field experiments could reveal whether "vibrational trapping" might be a new tool for managing the invasive pest.
Invasive species are a perpetual threat to U.S. agriculture, natural resources, and public health, and we're seemingly inundated with new ones every time you open the news. Is progress possible, or are we destined to spin on an invasive species hamster wheel?
Every invasive tree in the United States was intentionally introduced, and these plants often out-compete native plants while negatively affecting insects and other animals that depend on native species. You can do your part to help insects and protect local ecosystems by choosing native plants in your landscaping plans.
Two researchers compile existing research and additional observations to update the list of potential host plants for the invasive spotted lanternfly, bringing the worldwide total of plants the insect will feed on to 103—of which 56 are present in North America.
