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."
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
What happens in the forest after Emerald Ash Borers kill a tree?
The little yellow ant is a tropical species, native to Madagascar, but now it's been found in Florida.
By Andrew Porterfield The red-eyed, spotted fly first appeared in the United States in strawberry, raspberry, and blackberry crops in Santa Cruz County, California, in 2008. Then the Southeast Asian […]
