When Stephen Nixon recently noticed a “beautiful” spotted lanternfly by his bag as he skateboarded in Brooklyn, he heeded the request of city officials. 

He stomped on it. 

“I don’t like killing things. Not many people do. I’ll catch and release cockroaches if I find them in my apartment,” Nixon said. But he said it “seems like something worse” if the insect’s population explodes. 

Kill-on-sight requests in New York City and elsewhere are a part of public campaigns to fight an invasive insect now massing and feeding on plants around much of the eastern United States. Pretty with red wing markings, the spotted lanternfly is nonetheless a nuisance and a threat — the sort of insect that inspires people to post about squishing and stomping them on social media. 

In cities, they swarm outside buildings and land on pedestrians. They excrete a sticky substance called honeydew that can collect on outdoor furniture. The sap-sucking insects also pose a danger to grapes and other agricultural crops, which is raising alarms this summer in New York state wine country. 

Across mid-Atlantic states, officials are asking people to help them track and slow the insect’s spread, even if they have to put their foot down. 

“Be vigilant,” said Chris Logue of New York’s Department of Agriculture. 

Entered country in 2014

A native of Asia, the spotted lanternfly was first identified in the United States in 2014, northwest of Philadelphia. It’s likely that insect eggs came over with a load of landscaping stones. Eight years later, there are reported infestations in 13 states, mostly on the East Coast, according to the New York State Integrated Pest Management program at Cornell University. Individual insects have been spotted in more states, with two turning up in Iowa this summer. 

The insect has been able to spread so far, so fast because it is a stealthy hitchhiker. Drivers this time of year unwittingly give lifts to adults, which look like moths, perched inside trunks, on wheel wells or on bumpers. 

“Check your vehicle,” Logue said. “What you’re really after is anything that maybe is alive, that is kind of hunkered down in there and is not going to get blown off the vehicle during the trip. Really, really important.” 

People also unknowingly transport spotted lanternfly eggs, which are laid later in the season. Females leave masses of 30 or more eggs on all sorts of surfaces, from tree trunks to patio furniture. Eggs laid on portable surfaces, like camping trailers and train cars, can hatch in the spring many miles away. 

Spotted lanternfly fighters are doing everything from applying pesticides to cutting down trees of heaven — another invasive species that is a favored host of the spotted lanternfly. But public involvement is front and center. 

In Pennsylvania, residents in quarantined counties are asked to check for the pests on dozens of items — from their vehicles to camping gear to lumber and shrubs — before heading to nonquarantined destinations. 

Be merciless

Around the East, people are being asked to report sightings to help track the spread. 

And if you see one? Show no mercy. 

“Kill it! Squash it, smash it … just get rid of it,” reads a post by Pennsylvania agricultural officials. 

New York City parks officials agree, advising: “Please squish and dispose.” 

“Join Jersey’s Stomp Team” read billboards in New Jersey showing a shoe about to stamp out an insect. 

Heide Estes did just that after seeing a spotted lanternfly on a Sunday walk in Long Branch, New Jersey, this month. 

“I came back, and I said to my partner, ‘You know, I saw a spotted lanternfly,’ ” Estes said, “and she was like, ‘Oh, I’m sure there’s more. Let’s go look.’ ” 

There were more. 

Her partner, an entomologist, put four in a plastic bottle to show co-workers on campus what they look like. They killed at least a dozen more. Many were massed on trees of heaven. 

“Clearly, the whole spot was infested,” she said. 

Nearing vineyards

Infestations in New York state had been concentrated in the metropolitan area but have spread close to the state’s wine-growing vineyards. Agricultural officials are concerned about the fate of vineyards in the Finger Lakes, the Hudson Valley and Long Island if infestations spread. U.S. Senator Chuck Schumer said Sunday that the insect could cost the state millions. 

“The spotted lanternfly sucks the sap out of the vines,” said Brian Eshenaur, an expert with the Cornell pest program. “And it makes them less hardy for the winter, so vines can be lost over the growing season.” 

Eshenaur said they’re more likely to spread into vineyards later in the season, when trees of heaven enter dormancy.

At Sheldrake Point Winery in the Finger Lakes, vineyard manager David Wiemann said workers in the rows already know to be on guard. 

“We’ve talked about how detrimental it would be to the vineyards,” Wiemann said. “So if they see one, they would let me know.”

A smaller dose of the monkeypox vaccine appears to still be effective and can be used to stretch the current supply by five times, the European Medicines Agency said Friday, echoing a recommendation made earlier this month by the U.S. Food and Drug Administration.

The EU drug regulator said in a statement that injecting people with one-fifth of the regular dose of the smallpox vaccine made by Bavarian Nordic appeared to produce similar levels of antibodies against monkeypox as a full dose.

The approach calls for administering Bavarian Nordic’s vaccine with an injection just under the skin rather than into deeper tissue, a practice that may stimulate a better immune response. People still need to get two doses, about four weeks apart.

The EMA said national authorities could decide, “as a temporary measure” to use smaller doses of the vaccine to protect vulnerable people during the ongoing monkeypox outbreak.

EU health commissioner Stella Kyriakides said the decision would allow the vaccination of five times as many people with the continent’s current supply.

“This ensures greater access to vaccination for citizens at risk and health care workers,” she said in a statement.

Earlier this month, the U.S. FDA authorized a similar plan to extend the country’s monkeypox vaccine stocks. The technique has previously been used to stretch supplies of vaccines during other outbreaks, including yellow fever and polio.

The unusual recommendations from both regulators acknowledge the extremely limited global supplies of the Jynneos vaccine, originally developed against smallpox. Bavarian Nordic is the only company that makes it, and it expects to have about 16 million doses available this year. On Thursday, the U.S. also announced a new agreement with a Michigan manufacturer to help speed production of 5.5 million vaccine vials recently ordered by the government.

The EMA authorized the vaccine in July based on experimental data that suggested it would work; the World Health Organization has estimated the shot is about 85% effective at preventing monkeypox.

Globally, there are more than 40,000 cases of monkeypox, of which about half are in Europe. Earlier this week, WHO chief Tedros Adhanom Ghebreyesus said there has been a 20% increase in cases reported in the last two weeks and that nearly all infections have been reported in men who are gay, bisexual or have sex with other men.

Tedros said WHO was in talks with vaccine manufacturers and countries to see if any might be willing to share doses. Africa has reported the highest number of suspected monkeypox deaths and although the disease has been endemic in parts of central and west Africa for decades, it has only a small supply of vaccines being used as part of a research study.

About 98% of monkeypox cases beyond Africa have been reported in men who are gay, bisexual or have sex with other men. WHO said there is no sign of sustained transmission beyond men who have sex with men, although a small number of women and children have also been sickened by the disease.

Monkeypox spreads when people have close, physical contact with an infected person’s lesions, their clothing or bed sheets. Most people recover without needing treatment, but the lesions can be extremely painful and more severe cases can result in complications including brain inflammation and death.

In the U.K., which at one point had the biggest outbreak outside Africa, officials said earlier this week they have seen signs the outbreak is slowing down.

The World Health Organization says clinical evidence shows two monoclonal antibody treatments are effective at saving the lives of many people stricken with the deadly Ebola virus.

The action follows a systematic review and analysis of randomized clinical trials of therapeutics for the disease.

WHO Team Lead for Clinical Care Janet Diaz says the evidence underpinning the recommendations comes from two clinical trials. The largest was done in the Democratic Republic of Congo in 2018 and 2019.

She says the trials were conducted during Ebola outbreaks, demonstrating quality control trials can be done even under the most difficult circumstances.

“The evidence synthesis that informs this guideline shows that mAb114 and Regeneron-EB3 reduced mortality. The relative risk reduction was about 60 percent…Between 230 to 400 lives saved per 1,000 patients. Translate that into the number needed to treat, you treat two to four patients, and you save one life.”

Ebola hemorrhagic fever is spread through blood or body fluids of a person who is sick with or has died of the disease. The worst Ebola outbreak occurred in West Africa between 2014 and 2016. Of the nearly 29,000 reported cases, more than 11,300 people died.

Diaz calls the development of monoclonal antibody therapeutics a very important advancement. However, she notes the drug itself is not the only solution. She says it must be given in a comprehensive, clinical setting along with other treatments.

“That includes early diagnosis so that treatments can be given as soon as possible and also the implementation of appropriate infection prevention and control to stop transmission…and treatment of co-infections and access to nutrition, psycho-social support, and, of course, access to care after discharge.”

Diaz says the two recommended therapeutics have shown clear benefits for people of all ages. She says they can be used on all patients confirmed positive for Ebola virus disease. That, she says, includes older people, pregnant and breastfeeding women, children, and babies born to mothers with confirmed Ebola within the first seven days after birth.

Microelectronics produced in the United States and allied countries are crucial components of Russian weapons systems used in the Ukraine invasion, according to a report by Britain’s Royal United Services Institute.

The RUSI report, Silicon Lifeline: Western Electronics as the Heart of Russia’s War Machine, says more than 450 foreign-made components have been found in Russian weapons recovered in Ukraine. The report’s authors say Moscow acquired critical technology from companies in the United States, Europe and Asia in the years before the invasion.

Ukraine says Russia fired more than 3,650 missiles and guided rockets into its territory in first five months of the war. Most of the weapons rely highly on Western-made microelectronic technologies, according to report co-author Gary Somerville, a research fellow at RUSI’s Open-Source Intelligence and Analysis Research Group.

“It doesn’t appear that they actually have the ability to reproduce – at least to the same level of sophistication and at scale – a lot of these critical microelectronics. These are the ones that would be absolutely essential for, for example precision-guided munitions which have very sophisticated processing units,” Somerville told VOA.

That includes Russia’s Iskander 9M727 cruise missile, one of its most advanced weapons. RUSI researchers recovered some missiles in the field inside Ukraine and inspect the microelectronics inside.

They found several Western-sourced components, including digital signal processors, flash memory modules and static RAM modules made by U.S.-based companies including Texas Instruments, Advanced Micro Devices and Cypress Semiconductor, along ethernet cabling that originated from American, Dutch and German companies.

Russia’s Kh-101 cruise missiles, some of which targeted the Ukrainian capital Kyiv, were found to contain 31 foreign components.

Common chips

All the microelectronics companies cited in the report said they comply with trade sanctions and they have stopped selling components to Russia. There is no suggestion in the report that the companies broke any export control laws.

“How is Russia possibly getting hold of this stuff? When we actually looked through a lot of these components, they are quite prosaic and in many ways ubiquitous, they can be found in any sort of electronics really – microwaves, dishwashers,” Somerville said.

Such microelectronics were freely available to Russia before its invasion of Ukraine.

However, RUSI also identified at least 81 components classified as “dual-use” by the U.S. Commerce Department and subject to U.S. export controls.

They include a high-performance CMOS static RAM microchip originally made by U.S.-based Cypress Semiconductor, found inside a handheld navigational system used by Russia’s special forces to pinpoint their position and estimate coordinates for precision artillery and air strikes.

“The component is a high-speed, ultra-low-power memory chip148 that is classified as a dual-use good for export purposes,” according to the RUSI report.

Two-thirds of the foreign components found in Russian weapons systems were manufactured by U.S.-based companies. Japan was the second-biggest supplier.

Export bans

Many of the microelectronics found in the weapons were decades old and, following Russia’s invasion of Ukraine in February, many states have banned the export of such components to Russia.

Somerville pointed to Russia’s history of using elaborate methods to procure technology, Somerville said.

“It’s through the use of a number of front companies that, on the surface when you conduct a due diligence check, appear to be legitimate — but in reality are actually, or can be somewhat affiliated with, large Russian companies that are actually members of the military-industrial complex,” he said.

The report details how Russia also uses false end-user certificates and transshipment companies based in third countries, including several in Hong Kong, to obscure the final destination.

It cites Russian customs records showing that in March 2021, one company imported $600,000 worth of electronics manufactured by Texas Instruments through a Hong Kong-based distributor. Seven months later, the same company imported another $1.1 million worth of microelectronics made by Xilinx, according to RUSI.

U.S. and allied sanctions imposed on Russian weapons manufacturers and companies supplying them with components must be tightened, Somerville said.

“What the sanctions and effective enforcement of these sanctions can do is raise the costs on Russia to acquire these particular microelectronics,” he said.

The report’s authors say Russia is now scrambling to procure microelectronics in bulk, and that its military could be permanently weakened if the supply can be cut off.
