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.
Study Shines a (Fluorescent) Light on Invasive Fruit Fly Trapping
To estimate the catch rate of traps for invasive spotted-wing drosophila fruit flies in tart cherry orchards, researchers at Michigan State University first marked thousands of flies with fluorescent dust and released them. Then they counted the recaptured flies under ultraviolet light.
Invasive Fly Targets North American Onions, Leeks, Related Crops
The allium leafminer damages crops such as onions, garlic, shallots, and leeks through larval feeding and adult egg-laying in plant tissue. Native to Europe, the invasive species was first discovered in North America in December 2015 in Lancaster County, Pennsylvania.
Spotted Lanternfly: States Urge Citizens to Report Sightings of Invasive Insect Hitchhiker
First encountered in the United States in Pennsylvania in 2014, the spotted lanternfly had spread to New York, Delaware, and Virginia by early 2018. The invasive insect threatens Tree of Heaven as well as grapes, hops, and fruit trees, and it has a penchant for hitchhiking. Anyone sighting spotted lanternfly is urged to report it to their state agriculture department or local extension office.
Flower Pots in Southwestern U.S. a Common Breeding Site for Aedes aegypti Mosquitoes
The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
Native to Asia, Found in New Jersey: The Curious Case of an Invasive Tick
In 2017, specimens of an "unusual-looking" tick were discovered in New Jersey and determined to be a species, Haemaphysalis longicornis, native to Asia. No established population of the species has ever been previously documented in the United States.
Domestic Sea Trade Aids Wood-Boring Beetles’ Range Expansion
A study by entomologists in Italy found that the abundance of bark- and wood-boring beetles outside their native range but still within the same country is correlated with levels of trade at nearby sea ports, suggesting domestic sea transportation plays a role in insects' intra-country range expansion.
After Emerald Ash Borer, Invertebrates on the Ground Get to Work
