Lab testing of the flight capability of the weevil Rhynchophorus palmarum shows some "super-flyers" can fly more than 100 kilometers in 24 hours. With the species appearing recently on both sides of the U.S.-Mexico border, the findings are a concern for California's $100 million date palm industry.
For the invasive fruit fly known as spotted wing drosophila, its success in expanding into new ranges is driven at least in part by a high degree of phenotypic plasticity—the ability to shift traits in response to environmental influences.
The mealybug species Nipaecoccus viridis, known as the lebbeck mealybug, is originally from Asia and was first found in Florida back in 2009, but in late 2018 it was found infesting citrus groves in the state. The author of a new report in the Journal of Integrated Pest Management discusses the implications of its arrival and the management options that are currently available and under evaluation.
A food-grade gum substance shows promise as a new tool for managing the invasive spotted-wing drosophila. The flies don't get stuck, but the scent interferes with their reproductive behavior, and the gum can last up to three weeks in the field.
