An Invasive-Species Success Story: The Eradication of the European Grapevine Moth in California
The successful eradication of the European grapevine moth (Lobesia botrana) in northern California after it was found there in 2009 offers important lessons for invasive species response. Researchers are studying the dynamics of the invasion and eradication effort to prepare future response plans for other potential invasive species both in California and beyond.
Why Researchers are Re-Creating an Infamous Hitchhiker’s Month-Long Journey Around the Globe
New Zealand is working hard to keep the invasive brown marmorated stink bug from reaching its shores, and researchers there are working with colleagues at the U.S. Department of Agriculture to understand the dynamics of the pest's ocean voyage aboard cargo ships bound for the island nation, in hopes of finding new ways to detect and prevent its arrival.
The Path Forward on Invasive Arthropods: Collaboration, Innovation, and More
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.
Khapra Beetle Can’t Beat the Heat
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.
In Search for Better Stink Bug Management, Scientists Look Up
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.
Why Taxonomic Preparedness is Critical for Invasive Species Response
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.
Potential Range for Asian Longhorned Tick Covers Much of Eastern U.S.
The invasive Asian longhorned tick could find plenty of suitable habitat in North America that is similar to its native region, according to new research from the Rutgers University Center for Vector Biology.
A Gathering of Minds on Managing Invasive Insects and Arthropods
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.
Attract-and-Kill Strategy Shows Promise for Managing Brown Marmorated Stink Bugs
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.
Field Tour Offers Close-Up Look at Invasive Species Security
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."
Stinking Here and There: The Painted Bug Bagrada hilaris Goes From Crops to Homes
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.
Invasive Insects: The Top 4 “Most Wanted” List
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.
Got Spotted Lanternfly Eggs on Your Tree? Send ‘Em Through the Wood Chipper
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.
Testing Shows Dry, Red Sticky Traps Improve Spotted-Wing Drosophila Monitoring
A new study finds spotted-wing drosophila prefer red, glue-covered monitoring traps made of plastic rectangles or spheres compared to the most commonly used clear deli-cup traps. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest.
Fruit DNA in Invasive Flies’ Guts Could Help Track Their Dispersal
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.
Invasive Tick Persists in New Jersey
Officials in New Jersey report that the invasive tick Haemaphysalis longicornis has successfully overwintered and was found once again on a rural property in mid-April 2018, after an infestation was reported there in 2017, the first such appearance of the species within North American borders.
