The spotted lanternfly was first detected in Pennsylvania in 2014 and has since spread to 26 counties in that state and at least six other eastern states. It's moving into southern New England, Ohio and Indiana.
This approximately 1-inch-long species from Asia has attractive polka-dotted front wings but can infest and kill trees and plants. We recently caught up with Professor Frank Hale, an entomologist who is tracking this species.
The Conversation: How did the spotted lanternfly get to the U.S., and how quickly is it spreading?
Frank Hale: It is native to India, China and Vietnam and probably arrived in a cut stone shipment in 2012. The first sighting was in 2014 in Berks County, Pennsylvania, on a tree of heaven—a common invasive tree brought to North America from China in the late 1700s.
By July 2021 the lanternfly had spread to about half of Pennsylvania, large areas of New Jersey, parts of New York state, Maryland, Delaware and Virginia. It also had been found in western Connecticut, eastern Ohio, and now Indiana.
To give an idea of how fast these lanternflies spread, they were introduced into South Korea in 2004 and spread throughout that entire country—which is approximately the size of Pennsylvania—in only three years. READ MORE
Diabetes surged among American children, teens and adolescents to 2017, according to new federally-funded research spanning nearly 20 years finding a 45% increase in type 1 diagnoses, and a 95% growth in type 2 diagnoses.
"Increases in diabetes are always troubling – especially in youth. Rising rates of diabetes, particularly type 2 diabetes, which is preventable, has the potential to create a cascade of poor health outcomes," Dr. Giuseppina Imperatore, chief of the Surveillance,
Epidemiology, Economics, and Statistics Branch in CDC’s Division of Diabetes Translation, said in a statement issued Tuesday. "Compared to people who develop diabetes in adulthood, youth are more likely to develop diabetes complications at an earlier age and are at higher risk of premature death."
Findings published in JAMA on Tuesday indicated that Type 1 diabetes persists as the most common type of diabetes among U.S. youth. Results stemmed from an average of 3.5 million Americans under age 20 studied on a yearly basis from 2001 to 2017 across areas of California, Colorado, Ohio, South Carolina, Washington State, Arizona and Mexico.
Results indicated significant increases in type 1 diabetes among Americans 19 years or younger, from 1.48 per 1,000 young people to 2.15 per 1,000 by 2017, or a 45% increase over 16 years, whereas the prevalence of type 2 diabetes among kids aged 10-19 increased from 0.34 per 1,000 youths to 0.67 per 1,000 youths, or a 95.3% increase over 16 years.
Study authors noted no significant differences in the increases in diabetes prevalence across sexes.
The study found the largest increases in type 2 diabetes were among Black and Hispanic youth, with increases in the estimated prevalence of type 1 diabetes greatest among Black and White youths. Kids under age 9 with type 2 diabetes were excluded from the study due to small sample sizes.
Diabetes is a chronic health condition impacting how the body converts food into energy. According to the Centers for Disease Control and Prevention (CDC), "If you have diabetes, your body either doesn’t make enough insulin or can’t use the insulin it makes as well as it should. When there isn’t enough insulin or cells stop responding to insulin, too much blood sugar stays in your bloodstream. Over time, that can cause serious health problems, such as heart disease, vision loss, and kidney disease." READ MORE
