New, Fast DNA Method Spots Pesticide-Resistant Ticks
In its effort to keep cattle fever ticks from escaping quarantine in five counties along the southern Texas border, researchers at the U.S. Department of Agriculture have developed an overnight DNA test that can detect ticks' genetic indicators of resistance to permethrin, a common pesticide used to manage ticks.
How to Tackle an Invasive Species Crisis? Build a Collaborative Team
The arrival of the invasive brown marmorated stink bug (Halyomorpha halys) drove a far-reaching, collaborative response by researchers, integrated pest management professionals, government agencies, and growers. A new article in the Journal of Integrated Pest Management looks back at this experience to share lessons learned for future invasive-species response efforts.
USA National Phenology Network Aids Management of Pest Insects With Life-Stage Forecast Maps
It's easier to manage an insect pest if you can predict where and when it's likely to show up, rather than trying to react after it appears. The USA National Phenology Network's "Pheno Forecast" maps offer daily updates that model the temperature conditions necessary for a dozen forest insect pests. A new article in the Annals of the Entomological Society of America showcases the tool, part of a new special collection on geospatial analysis of invasive insects.
Advocacy in Action: A Symposium for Everyone Interested in Science Advocacy and Invasive Species
The ESA Student Affairs Committee’s symposium at Entomology 2019 will focus on addressing invasive species issues through collaboration, policy, and public engagement.
Spotted-Wing Drosophila: New Seasonal Activity Model Will Aid IPM Efforts
Seven years' worth of trapping data for the invasive spotted-wing drosophila in Michigan offer an enhanced view of the pest's seasonal activity and abundance patterns, a boon for fruit growers and integrated pest management pros in temperate regions.
Spotted Lanternfly: Large Potential Range in U.S. and Beyond
A new study published today in the Journal of Economic Entomology models potential suitable habitat for the invasive spotted lanternfly and shows large swaths of the United States and beyond are likely to be vulnerable should the spotted lanternfly continue to spread.
Large-Scale Study Points to Simpler Trap for Monitoring Brown Marmorated Stink Bugs
Tested in more than 100 locations across the U.S., a clear sticky-panel trap proves effective in attracting brown marmorated stink bugs, putting an easier-to-use tool in the hands of growers and IPM professionals for monitoring populations of the invasive pest.
Impact of Invasive Japanese Barberry Cascades Through Local Food Webs
Dense thickets of invasive Japanese barberry significantly reduce the diversity and numbers of insects and arthropods in forests, according to new research. The ripple effects can extend upward throughout local ecosystems, even affecting human health via an increased presence of Lyme disease.
Early Detection, Collaboration Key to Invasive Fruit Fly Eradication in Florida
The largest-ever outbreak of the invasive oriental fruit fly in Florida in 2015 was successfully quelled through a six-month eradication program that combined outreach, control, science, technology, and regulation.
A Promising New Parasitoid Drills Down on Emerald Ash Borers
In a recent study, the wasp Spathius galinae successfully established wild populations and outperformed other parasitoids in attacking invasive emerald ash borers in three northeastern states in the U.S. Researchers say it could become a useful biological control agent to protect native ash trees.
Drosophilid Melting Pot: African Fig Fly Meets Spotted-Wing Drosophila in the U.S.
The African fig fly (Zaprionus indianus) is an invasive fruit fly in North America that has been found commingling with its cousin spotted-wing drosophila (Drosophila suzukii), sometimes even using the latter's egg-laying sites for its own. A new profile in the Journal of Integrated Pest Management highlights the African fig fly's biology and range and offers options for management.
Mosquito Management is Key in Creating Popular Urban Wetlands
A study that shows mosquitoes might benefit from wetland-management tactics aimed at protecting frogs illustrates the complicated ecological dynamics present in urban wetlands. Understanding the habitat requirements and ecological interactions of local mosquito species is critical to balancing such wetlands' risks and benefits.
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.
