Resilient gypsy moth continues to shrug off best pesticides

29.04.2010
The gypsy moth, a highly destructive insect that has damaged millions of acres of forests and urban landscapes, continues to slowly spread throughout the country despite the use of safer, more effective pesticides, according to an article in Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.

C&EN Senior Correspondent Stephen K. Ritter notes that the gypsy moth has been plaguing the Northeastern United States and parts of Canada for more than a century. The leaf-munching insects rapidly defoliate trees, leaving trees vulnerable to destruction by disease or other pests.

Pest-management workers have counterattacked with a series of powerful pesticides and other weapons over the years, including most recently a sex hormone that disrupts mating and a virus-based pesticide that kills gypsy moth larvae.

Despite these efforts, gypsy moths keep on fluttering and spreading across the nation. A final victory may not be in the cards, but scientists and government agencies are continuing to try new and innovative ways to limit the spread of these tough bugs, the article notes.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
