UrduFor the first time in more than 200 years, two broods of cicadas Brood XIX, known as the Great Southern Brood, and Brood XIII, known as the Northern Illinois Brood will emerge from the ground simultaneously. Hannah Burrack, professor and chair of the Department of Entomology at Michigan State University, answers questions about this rare occurrence.

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 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.
Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years
Insects react sensitively when temperature and precipitation deviate from the long-term average. In an unusually dry and warm winter, their survival probabilities are reduced; in a wet and cold spring, hatching success is impaired.

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.
Newly sequenced hornet genomes could help explain invasion success
The genomes of two hornet species, the European hornet and the Asian hornet (or yellow-legged hornet) have been sequenced for the first time by a team led by UCL (University College London) scientists.

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.
Bumblebees Appear to Feel Pain
New research by a team at Queen Mary University of London shows that bumblebees can modify their response to ‘noxious’ (painful) stimuli in a manner that is viewed in other animals as consistent with the ability to feel pain.
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.

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.

‘Insect apocalypse’ may not be happening in U.S.
Scientists have been warning about an “insect apocalypse” in recent years, noting sharp declines in specific areas — particularly in Europe. A new study shows these warnings may have been exaggerated and are not representative of what’s happening to insects on a larger scale.
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.
