News at a glance: ‘Cherry-picked’ vaccine guidance, AI-written papers, and an apology for prisoner research
ENVIRONMENT Utah’s Great Salt Lake may dry up within 5 years North America’s largest saline lake could be gone by 2028 if water inflows are not restored, researchers warned last week. The Great Salt Lake in Utah has lost nearly three-quarters of its water and 60% of its surface area since 1950, a report from 32 scientists at multiple institutions concludes, and a recent drought has accelerated the losses. To restore the lake, farmers, homeowners, and others will need to reduce the amount of water they take from feeder streams by 30% to 50% . If they don’t, the continent could lose a key habitat ...

Why Scientists Want You to Kill Spotted Lanternflies
As invasive spotted lanternflies continue moving through the United States, local agricultural agencies have launched “If you see it, kill it” campaigns urging people to kill the bugs in order to prevent any further spread across the U.S. In response to the proliferating insect, earlier this week Senator Chuck Schumer (D., NY) called for $22 million more in funding for a U.S. Department of Agriculture program that targets invasive species; these are species that aren’t native to an area and can quickly become overpopulated, wreaking havoc on their new environment. “We need to stomp out this bug bef...

Trillions of ‘Brood X’ Cicadas Are About to Emerge Across the U.S. to Sing, Mate and Die. Here’s What to Expect
This coming May, millions of people around the United States will have front-row seats to an extraordinary entomological event: Trillions of Brood X cicadas across 15 states will emerge almost synchronously after having spent the last 17 years underground. The males will take up elevated positions, each buzzing as loud as a lawnmower to attract females. After mating, the adult cicadas will die off en masse just about as quickly as they arrived—likely sometime in late June or July—while their offspring tunnel underground, not to emerge until 2038, when the dance will begin anew. Annual, or “dog day,”...

Our Place in Democracy: A Letter from the ESA President
Annapolis, MD; January 7, 2021 —To ESA members and the entomology profession at large: On behalf of the Governing Board of the Entomological Society of America, today I echo the chorus of shock and condemnation at yesterday’s violent assault on our nation’s democratic institutions. It is a heartbreaking day for the United States of America. As a scientific society, ESA cannot pursue its mission to improve the world through scientific progress when ongoing crises in American leadership create constant turmoil that hinders our members from doing their work or simply living their lives. The orderly and peaceful transi...

Domestic Triatoma sanguisuga-Human Exposure in the South Carolina Coastal Region.
Abstract A collaborative investigation was initiated in rural coastal South Carolina in response to a reported triatomine bite. The eastern conenose bug, Triatoma sanguisuga, was identified and tested for Trypanosoma cruzi. The insect was negative by PCR, and no additional triatomines were found in the vicinity of the home. This is the first published report of a bite from T. sanguisuga in South Carolina despite the fact that triatomine vectors have been documented in the state since the 1850s, and specimens have been collected from homes in the past. Sylvatic T. cruzi reservoirs are common throughout the southeas...

Dealing with Food Insecurity, on a Longer Term
Longer term investments are needed to enable the over 500 million small holder farmers in developing countries to grow more food, thus increasing their incomes and resilience. Credit: Miriam Gahtigah/IPS By Esther NgumbiILLINOIS, United States, Jul 16 2020 (IPS) African countries are beginning to reopen borders, and this is finally enabling many citizens to resume their normal life. However, there is still an urgent need for African countries to prioritize agriculture to tackle food insecurity issues that have been exacerbated by COVID and will continue to be an issue into the near future. According to the latest estimates...

Why Black Lives Matter to Entomology
Annapolis, MD; June 1, 2020 —The field of entomology has been immeasurably enriched by black scientists, including Dr. Charles H. Turner, likely the first black professional entomologist in the United States, and Dr. Ernest J. Harris, who will be honored in the2020 ESA Founders ’ Memorial Award Lecture, among many others. But these scientists have faced numerous barriers, both historically and, sadly, through the present day.

Insect Experts Say People Should Calm Down About the Threat of ‘Murder Hornets’
Insect experts say people should calm down about the big bug with the nickname “murder hornet” — unless you are a beekeeper or a honeybee. The Asian giant hornets found in Washington state that grabbed headlines this week aren’t big killers of humans, although it does happen on rare occasions. But the world’s largest hornets do decapitate entire hives of honeybees, and that crucial food pollinator is already in big trouble. Numerous bug experts told The Associated Press that what they call hornet “hype” reminds them of the 1970s public scare when Africanized honeybees, nicknamed &l...

Diverse Voices Should Be Represented in Coronavirus Experts on TV
By Esther NgumbiILLINOIS, United States, Apr 6 2020 (IPS) During a crisis, such as the novel coronavirus, whose impact changes with every passing minute, the urge to listen to and watch the news, and get firsthand insights and real time updates can be constant. Indeed, millions of Americans are frequently checking the news. I know I am. What I’ve noticed on three of the major TV stations I’ve watched across the day is the absence of diversity in the experts commenting on the pandemic. This is inexcusable. The United States is made up of people of many different races and ethnicities, many of whom are professional exper...

Is Our Academic System Ready for a New Coronavirus Normal?
Credit: Pîxabay.By Esther Ngumbi and Brian LovettILLINOIS, United States, Mar 11 2020 (IPS) Institutions of higher education have a responsibility to lead by example and to provide current, high-quality information to the people and communities that support them. This responsibility is no clearer than during a public health and information crisis like the one presented by this novel coronavirus. State and local governments in particular should be able to rely on Universities for guidance on protective evidence-based precautionary measures, whether it’s cancelling events, closing schools or formulating public health post...

The Transcriptome of the Salivary Glands of Amblyomma aureolatum Reveals the Antimicrobial Peptide Microplusin as an Important Factor for the Tick Protection Against Rickettsia rickettsii Infection
Conclusion In conclusion, our data show that R. rickettsii exerts a modulatory effect on the transcriptional profile the SG of A. aureolatum. Moreover, RNAi experiments demonstrated that the knockdown of one microplusin increases the susceptibility of ticks to infection, suggesting that this is one important factor for the control of R. rickettsii. The functional characterization of the additional CDSs modulated by infection is warranted and might reveal other factors that interfere with the acquisition and/or transmission of this tick-borne pathogen. Ethics Statement All procedures involving vertebrate animals were car...

Amino Acid Utilization May Explain Why Bemisia tabaci Q and B Differ in Their Performance on Plants Infected by the Tomato yellow leaf curl virus
Discussion Research has shown that vectored viruses can alter host plant phenotypes so as to change interactions with other organisms, including interactions between plants, viruses, and insect vectors of viruses (Mauck et al., 2012, 2018; Casteel and Falk, 2016; Eigenbrode and Bosque-Perez, 2016; Mauck, 2016). Insect-vectored viruses can alter many host plant factors, including odors, induced defenses, visual and tactile characteristics, sugars, free amino acids, and secondary metabolites (Bosque-Perez and Eigenbrode, 2011; Casteel et al., 2014; Mauck et al., 2014a,b). In our study, TYLCV significantly altered the free a...

Docosahexaenoic Acid Increases the Potency of Soluble Epoxide Hydrolase Inhibitor in Alleviating Streptozotocin-Induced Alzheimer ’s Disease-Like Complications of Diabetes
Conclusion In the present study, we demonstrated that sEHI alleviates cognitive and memory impairment associated with diabetes-induced Alzheimer-like complication. The positive effect of sEHI TPPU on memory was associated with a reduction in oxidative stress and inflammation in the brain with a parallel decrease in the mRNA level of APP and activity of AChE. The DHA potentiated the effect of TPPU. Edaravone at a higher dose also alleviated memory impairment via decreasing oxidative stress and inflammation. Author Contributions RP, MA, SA, ML, and SG planned the experiments. RP, NB, KG, MA, and SA performed the experimen...
