How Insects Evolved to Ultrafast Flight (And Back)

This asynchronous beating comes from how the flight muscles interact with the physics of the insect’s springy exoskeleton. This decoupling of neural commands and muscle contractions is common in only four distinct insect groups. For years, scientists assumed these four groups evolved these ultrafast wingbeats separately, but research from the Georgia Institute of Technology and the University of California, San Diego (UC San Diego) shows that they evolved from a single common ancestor. This discovery demonstrates evolution has repeatedly turned on and off this particular mode of flight. The researchers developed physics models and robotics to test how these transitions could occur.

These Robots Helped Understand How Insects Evolved Two Distinct Strategies of Flight

Robots built by engineers at the University of California San Diego helped achieve a major breakthrough in understanding how insect flight evolved, described in the Oct. 4, 2023 issue of the journal Nature. The study is a result of a six-year long collaboration between roboticists at UC San Diego and biophysicists at the Georgia Institute of Technology.

How Insects Track Odors by Navigating Microscale Winds

Insects use odor plumes — which travel like smoke and form when the wind blows odor molecules from their source — to track down sources such as flowers or pheromones. But wind tunnels are typically unable to replicate realistic outdoor wind conditions. In Physics of Fluids, by AIP Publishing, University of Nevada at Reno researchers decided to explore microscale wind conditions in various outdoor environments to better understand what flying insects might experience while tracking odor plumes.

Climate change leads to invasive insect expansion on West Coast

Climate change has led to warming temperatures in the Pacific Northwest, leading some insect species to expand their range into more northerly oak savannas, according to new research from Binghamton University, State University of New York.

A midge fly can be a source of currently used pesticides for birds, bats

Researchers reporting in ACS’ Environmental Science & Technology have observed that non-biting midge larvae accumulate contemporary pesticides from polluted water and retain the substances into adulthood. As a result, animals that eat the adult flies could consume small amounts of pesticides daily.

Protecting gardens and crops from insects using the ‘smell of fear’

Herbivorous insects are a threat to gardeners’ hard work, and are increasingly resistant to pesticides. Today, scientists report they have bottled the “smell of fear” from predators to repel destructive insects without the need for harsh substances. They will present their results at ACS Fall 2021.

New beetle species discovered and named after iconic sci-fi heroines

The original Star Trek television series took place in a future when space is the final frontier, but humanity hasn’t reached that point quite yet. As researchers like Michigan State University entomologists Sarah Smith and Anthony Cognato are reminding us, there’s still plenty to discover right here on Earth.
Working in Central and South America, the duo discovered more than three dozen species of ambrosia beetles — beetles that eat ambrosia fungus — previously unknown to science. Smith and Cognato described these new species on June 16 in the journal ZooKeys.

Trillions of cicadas are beginning to emerge across the U.S. and one Bowling Green State University expert is available to add insight, context to your reporting

Trillions of cicadas are beginning to emerge in parts of the U.S., and Dr. Daniel Pavuk with Bowling Green State University knows all about the bugs and can add helpful information and context about them to your reporting. Labeled as…

Cannabis use disorder linked to increased complications after spinal surgery

Dragonfly wings, lotus leaves, cicada wings — thanks to millennia of evolution, nature has optimized the ways these surfaces and others behave to offer antibacterial functionality. An international, interdisciplinary team of researchers is trying to find the best way to translate these features to create nature-inspired bactericidal surfaces for use in medical implants. They discuss the surface structures and chemical compositions for an ideal implant material in the journal Applied Physics Reviews.

Rutgers Expert Available to Discuss 17-Year Cicadas in N.J.

New Brunswick, N.J. (March 18, 2021) – Rutgers University–New Brunswick entomologist George C. Hamilton is available for interviews on the upcoming emergence of 17-year cicadas in New Jersey. The big, noisy insects appear suddenly in late May or early June. “This spring, we will…

Rutgers Experts Can Discuss Invasive Spotted Lanternfly Spread in N.J.

New Brunswick, N.J. (Oct. 1, 2020) – Rutgers University–New Brunswick Professor George C. Hamilton and Associate Professor Anne L. Nielsen can discuss the spread of and threat posed by the invasive spotted lanternfly, a destructive pest, in New Jersey. “Their…

Decline of Bees, Other Pollinators Threatens U.S. Crop Yields

Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world’s crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.

Rutgers Experts Available to Discuss Invasive Asian Giant Hornet

New Brunswick, N.J. (May 6, 2020) – Rutgers University–New Brunswick experts are available for interviews on inquiries about the invasive Asian giant hornet (Vespa mandarinia). While media reports have triggered concern over the large pest, there are no reports of…

Mosquitoes are drawn to flowers as much as people — and now scientists know why

Scientists have identified the chemical cues in flowers that stimulate mosquitoes’ sense of smell and draw them in. Their findings show how cues from flowers can stimulate the mosquito brain as much as a warm-blooded host — information that could help develop less toxic repellents and better traps.
