Even humble fruit flies organize themselves into regularly spaced clusters, researchers have found. Within those social networks, certain individuals will often stand out as “gatekeepers,” playing an important role for cohesion and communication within that group. New research published Tuesday in the journal Nature Communications has identified a gene responsible for regulating the structure of social networks in fruit flies. The study opened up new opportunities for exploring the molecular evolution of social networks and collective behavior in other animals.

The insects will infiltrate a much bigger geographical area than similar occurrences in most years because they’re part of the dual emergence of two particular periodical cicada broods. Although the full-scale emergence isn’t underway yet, experts have some guidance on how to prepare for cicada season. A periodical cicada that has just shed its outer skeleton crawls among holes dug by emerging cicada nymphs on May 20, 2021, in Takoma Park, Maryland. A young tree in Takoma Park, Maryland, is draped in netting in May 2021 to protect its small branches from being damaged by periodical cicadas laying their eggs in them. It’s not clear why periodical cicadas evolved to emerge every 13 or 17 years.

Typical spiders — and most creatures — tend to find the noise and wind disturbance from nearby busy roads to be too stressful, but the Jorō spider doesn’t seem to mind much, according to a new study published in Arthropoda on February 13. University of Georgia ecology students and study coauthors Kade Stewart, Caitlin Phelan and Alexa Schultz handle a Jorō spider. What to do when you come across a Jorō spiderAs the nonnative Jorō spider continues to spread in the region, the spiders pose a threat to native species that are beneficial to the environment. While conducting the study, the researchers found evidence of the Jorō spiders coexisting with native spiders, Davis said. And the Jorō spiders eat species that are good and bad for the environment, including the infamous lantern fly, he added.

☆ ‘Moths to a flame’: Insect behavior around light isn’t about attraction, scientists say
▼ + stars: | 2024-02-07 | by ( Taylor Nicioli | ) edition.cnn.com time to read: +7 min

Gaining a better understanding of the impact of artificial light on these winged creatures is crucial as light pollution plays an increasing role in the decline of global insect populations, the researchers wrote. Artificial light confuses nocturnal insectsWhen artificial light does not interfere, nocturnal insects keep their backs pointed toward whatever direction is brightest, which is typically the sky versus the ground. By using insect-scale motion-capture cameras, the researchers determined that the flying insects exhibited three consistent behaviors: orbiting, stalling and inverting. Moths and other insects can become trapped in a disorienting orbit around artificial light sources such as street lamps and porch lights. The new findings could help with conservation by fueling research on how to minimize the effects of light pollution on the insects, Dombroskie said.

The question of what brings insects toward lights of all kinds — from flames to porch lamps — is an ancient one. AdvertisementIt was as if they were using the light source as a way to orient themselves to the sky. Sam FabianBut Fabian said they tested this theory and found that some insects started traveling in a different direction when a new light source switched on. A less-bright future for insectsThere's a reason scientists have long sought to answer the question of why insects are attracted to artificial light. Oboyski also worries that light pollution is impacting the way insects navigate through their environments.

Healy, who is also president of the American Mosquito Control Association, offered Louisiana, which is home to many swamps where mosquitoes thrive, as an example. “Disease-transmitting mosquito species, such as Aedes aegypti and Aedes albopictus, are invasive species in many parts of the world. As for the Anopheles mosquitoes, which transmit malaria, things are a little different. … We are constantly educating mosquito control workers to follow these practices.

DHAKA, Aug 5 (Reuters) - Bangladesh is grappling with a record deadly outbreak of dengue fever, with hospitals struggling to make space for patients as the disease spreads rapidly in the densely-populated country. Hospitals, especially in capital Dhaka, are struggling to find space for the large number of patients suffering high fever, joint pain and vomiting, health officials said. There is no vaccine or drug that specifically treats dengue, which is common in South Asia during the June-to-September monsoon season, when the Aedes aegypti mosquito that spreads the deadly virus thrives in stagnant water. This year's deaths already top the previous record of 281 from last year, with the number of people infected just behind the 62,423 cases of 2022. "This is the reason why we saw such a high number of dengue cases in July.

AFRAM, an annual cultural festival celebrating Black excellence, was held over Juneteenth weekend at Druid Hill Park in Baltimore, Maryland (here), (aframbaltimore.com/about-afram). Weeks later, Instagram posts shared a clip from the festival that shows attendees swatting and fanning themselves and includes the text: “Helicopter released deadly mosquitoes in Baltimore, MD AFRAM 2023” (here). In other posts from the event, however, users say the flying bugs were gnats, not mosquitoes (here), (here). MALE MOSQUITOES SWARM, DON’T BITEMale mosquitoes swarm to mate but don’t bite, and the swarming flies in social media posts do not look like mosquitoes, said George Dimopoulos, a deputy director of the Johns Hopkins Malaria Research Institute (here). Social media clips of a Baltimore festival do not show “deadly mosquitoes,” entomology and health experts said.

☆ This ‘Alien’ Is Missing Something Found in Every Other Male Beetle
▼ + stars: | 2023-07-08 | by ( Sofia Quaglia | ) www.nytimes.com time to read: +1 min

Wings consume a lot of energy, so throughout evolutionary history, many insect species have independently lost the ability to fly. But there are more than a half-million known beetle species, and until now, all have had at least some form of hard forewing elytra. Dr. Ferreira also connected the species to a poorly understood evolutionary trend he and others have studied called paedomorphosis. In this phenomenon, adult females of some beetle species retain a few of their juvenile features, look more like larvae and sometimes even lose their wings. The winglessness of the male Xenomorphon baranowskii resembles what has been found in females of those beetle species.

Here’s the lowdown on how mosquitoes hunt us, what attracts them, and what scientists recommend for keeping them at bay. The science of mosquito bitesMost of the time, mosquitoes drink plant nectars and juices, and even help pollinate flowers. “How attractive you think you are to mosquitoes might not necessarily correlate with how attractive you actually are to the mosquitoes,” McMeniman said. The itchiness and discomfort from mosquito bites come later when the perpetrator is no longer at risk of getting swatted. No silver bullet exists to protect yourself from mosquito bites, but get a good bug spray and reapply it as needed.

A video circulating online shows a small sap-sucking insect called an aphid, not a genetically modified mosquito with a number stamped on it released by philanthropist Bill Gates, as online posts claim. Bill Gates was very vocal about releasing millions of GMO [genetically modified organism] mosquitos into the public.”Another example can be seen (here). However, the video shows a small insect called an aphid, not a GMO mosquito. A representative for the Gates Foundation said the claim that the video showed a genetically modified mosquito with a number or barcode stamped on it released by the Gates Foundation was false. The video shows an aphid, not a mosquito with a number stamped on it and released by Bill Gates.

Few causes have united the country like this summer’s multistate effort to kill spotted lanternflies, the colorful invasive insects that have wreaked havoc in at least 14 states. Now, as adult lanternflies begin to perish during the winter, experts say those efforts might have curbed the species’ spread to some degree. Anne Johnson, a doctoral student studying the spotted lanternfly in Hoover’s lab at Penn State, believes the viral trends can make a difference. Spotted lanternflies are native to China, where they don’t often become a pest. “We’ll always have to deal with spotted lanternfly,” Johnson said.

Penn State's PlantVillage uses technology solutions and field teams to increase farmers' crop yield. As warming temperatures spawn more crop pests, groups, including PlantVillage, are increasingly using artificial intelligence to protect agriculture. Each year, plant diseases cost the global economy more than $220 billion, while invasive insects cost at least $70 billion. The climate crisis increases crop diseases and pests — like the desert locust, which could spread because of warming temperatures. Farmers are encouraged to plant trees with biochar, a soil additive that can store carbon dioxide for centuries.
