Invasive insects and related arthropod species are a global challenge that transcend national borders. Stakeholders from the United States, Canada, and around the world convened in Vancouver in November 2018 to chart a path forward. Here are the key calls to action they identified to address the challenge of invasive arthropod alien species.
The khapra beetle does outsize damage to stored grains and is a top target at ports and border crossings. Researchers in Canada have found the threshold temperature that will kill the beetle at all life stages, even diapause.
A parasitoid wasp from Asia offers promise for biological control of the brown marmorated stink bug in North America, but new research suggests that monitoring efforts using primarily ground-level traps may be looking in the wrong place.
The story of "Team Trissolcus," insect taxonomists who sprang into action to identify the parasitoid wasps that might help us fight the invasive brown marmorated stink bug.
Part of the Grand Challenge Agenda for Entomology, the summit “Addressing the North American and Pacific Rim Invasive Insect and Arthropod Species Challenge,” drew more than 150 experts in invasive species from academia, industry, government, and entomological societies, hailing from Canada, the United States, and beyond.
By using the brown marmorated stink bugs' own aggregation pheromone, the pests can be lured into a condensed area, thereby reducing the area that a grower must spray with insecticide. A two-year study in apple orchards suggests the method could soon become economically feasible.
In August 2018, a diverse group of stakeholders gathered for the Entomological Society of America Plant-Insect Ecosystem Section's Science Policy Field Tour, "Invasive Species Security: Protecting Our National Health, Food Supply, and Environment."
A survey of mosquitoes in Pennsylvania discovered 12 mosquitoes parasitized by larval mites. Water mites can reduce the survival and reproductive success of mosquitoes, and entomologists are investigating such parasitism to evaluate its potential as a method for biological control efforts.
A new study shows that harlequin bugs can adapt their pigmentation (or melanin levels) during their developmental stages based on outside temperatures. Such thermal melanism enhances the pest species' potential to invade new regions and environments.
When a foreign parasitoid wasp was introduced to North America to control invasive pea aphids, it outcompeted most native wasps, except for one: Praon pequodorum. Its secret weapon: a resistance to pea aphids' natural defenses.
The sting bug species Bagrada hilaris, sometimes known as the painted bug or bagrada bug, arrived in Chile in 2016 and has quickly become a pest of crops—but, for the first time, it has also begun to infest homes, as reported this month in the Journal of Medical Entomology.
The list of invasive insects in the United States is a long one, but one entomologist offers his list of the top four "most wanted"—plus a note about how entomologists are working to better manage the challenge of invasive insect species.
The invasive spotted lanternfly often lays its eggs on tree limbs and trunks. A new study finds that putting infested wood through a wood chipper effectively destroys spotted lanternfly egg masses, and researchers recommend the practice for reducing the potential spread of the pest.
Donna Leonard, forest entomologist at the U.S. Forest Service, has piloted one of the most successful forest insect-management programs in the world for over 20 years running, all while navigating a career in a male-dominated field.
The return of the screwworm to Florida in 2016 was a surprise, but entomologists with the USDA and local, state, and international partners were prepared to respond. A new, in-depth report in the Journal of Medical Entomology shares a detailed account of their work re-eradicating the pest via the sterile insect technique—plus new lessons learned along the way.
A recent study at North Carolina State University shows that DNA analysis of spotted-wing drosophila (Drosophila suzukii) flies can detect whether they fed on strawberries as much as seven days prior. Researchers hope the proof of concept will lead to more accurate analysis of the invasive pest's dispersal in the field.
A recent study in Oregon details the predatory habits of the wasp Astata unicolor—its preferred prey is the invasive brown marmorated stink bug—and notes its potential as a native natural enemy of the invasive pest.
