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.
How an “Insect Ecologist at Heart” Got Focused on Pest Management Research
Lauren Diepenbrock, Ph.D., a postdoctoral researcher at North Carolina State University and soon to be an assistant professor at the University of Florida, says she enjoys "figuring out how insects, particularly invasive species, make use of the available resources to be successful."
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.
Fallen Fruit Breeds Invasive Flies
By removing potential breeding sites such as fallen fruit, population levels of invasive spotted wing drosophila could be reduced
How Salt, a Coffee Filter, and a Microscope Could Aid in Managing Spotted-Wing Drosophila
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 […]
Could Repellents Be Useful in Protecting Crops From Spotted-Wing Drosophila?
By Edward Ricciuti Cornell University scientists are tuning up the entomological version of psych war tactics that, instead of killing insect pests outright, manipulate their behavior so they avoid crops […]
Designing Effective Baits for Spotted Wing Drosophila is No Easy Task
By John P. Roche Spotted wing drosophila (Drosophila suzukii), is an invasive fruit fly species from eastern Asia, first seen in the United States in 2008. The species is devastating […]
New Formula Doubles Performance of Spotted Wing Drosophila Lure
To slightly modify an old adage, you can catch more flies with increased levels of acetoin, acetic acid, and ethanol than with methionol. Specifically, the fly in question is spotted […]
Et Tu, Fruite? Attracticidal Sphere Lures Fruit Flies to Their Demise
It looks like a fruit, but it’s definitely not as healthy. It’s the attracticidal sphere, and a new study shows it to be a promising tool for managing the invasive […]
A Spoonful of Sugar Helps Insecticide Go Down
The spotted wing drosophila (SWD) is a small fly that was first discovered in the western U.S. in 2008. Since then it has colonized many fruit-growing areas in North America […]
