  • Millions of sterile flies are curbing their spread

    Topline:

    Invasive Mediterranean fruit flies are a major threat to agriculture, and to fight them the state regularly drops millions of sterile male flies all over Southern California. They’re raised, prepped and sent out via a facility near Long Beach.

    A long-term problem: The state has been dropping flies en masse for about 30 years, the idea being that the sterile flies will try and mate with fertile, invasive females, limiting reproduction.

    A long-term solution: An increased amount of flies will be dropped over a recently quarantined area in and around Leimert Park, at least through June. After that, regular droppings will continue for the foreseeable future.

    The small, two-engine Beechcraft King Air is getting jostled by light winds over the L.A. basin. Having taken off from Los Alamitos Army Airfield Base, it’s flying toward one of the 1,750 square miles across Southern California it regularly covers.

    The pilot is guiding the plane while hundreds of thousands of his passengers are crammed inside metal chambers right behind his seat. They're kept in comas by refrigeration, meant to keep them from hurting themselves while in the tight space.

    They’ll wake up only after the pilot opens the trap door, and they start to warm as they fall through the sky, cascading over the city of Los Angeles some 2,000 feet below.

    Every week, 3 to 9 million sterile male Mediterranean fruit flies are dropped over Los Angeles, Orange, Riverside and San Bernardino counties as part of the California Medfly Preventative Release Program — a critical tool in stopping the spread of invasive fruit flies, which can threaten the state's agricultural industry.

    Once they land on yards and in fruit trees, they're hardwired to seek out female flies to copulate with. The idea being that if the state drops enough sterile flies, they’ll preoccupy fertile females that get brought in on produce, and stop them from reproducing. The flies can lay their eggs beneath the skins of various crops like pomegranates and figs. When the larvae hatch, they eat the produce, drop to the ground and pupate in the soil, before turning into adult flies. Leaving behind damaged goods.

    Just last month, five invasive Mediterranean fruit flies were discovered in the Leimert Park area. Since then, the program has increased its drops over the area to 6 million flies per week, and it will continue with the schedule until at least next June to make sure the problem is solved.

    A fruit fly’s trans continental journey 

    While the program’s home is at the Los Alamitos Joint Forces Training base near Long Beach, a sterile fly’s journey begins in either Hawaii or Guatemala.

    “We want to keep our breeding colonies offshore in an area where the fly is already established in the event any flies escape the facility, they don’t start an infestation,” said Ian Walters, director of the medfly preventative release program at Los Alamitos.

    Adult female flies have their eggs collected from large mating cages, and placed on an edible bedding material, so the larvae have something to munch. Once they’re ready to pupate, they’ll pop themselves out of the trays and into water baths, where they’re once again gathered. This time though, they’re tossed into a giant mixer and covered in pink dye that’ll help scientists identify them with a UV light if they’re caught in traps throughout L.A.

    Along the way they’re irradiated with Cesium-137 to make sure that they’re sterile, and then shipped via commercial airlines to California, where about 225 million pupae arrive per week.

    Turned on by ginger and dropped from a plane

    Once at Los Alamitos, they go into a hot and humid bungalow, where they become adult flies, munching on a mixture of seaweed extract, sugar and water.

    Strangely enough, when you walk into check them out in their giant metal towers, the entire room smells like fresh baked gingerbread.

    “Ginger root oil has a natural organic compound in it, which increases the mating competitiveness of the sterile males. They also tested orange oil, which has that same compound. But we found that ginger root oil was the most effective,” Walters said.

    From there, they get put into refrigerated trucks and are chilled to 38 degrees so that they fall into comas. They're then placed into special hoppers ready to be dropped from an airplane.

    If they wake up when they’re crammed into the tight space, they could injure themselves, so they sleep until they warm up as they fall through the sky.

    The length of an individual fly’s life can vary, but typically lasts around 30 days.

    How effective is the program?

    There doesn’t seem to be much debate that the program has helped mitigate the number of medfly outbreaks since it began.

    “They haven’t had as many outbreaks as prior to that. So in that sense it’s effective in suppressing them,” said James Carey, an entomologist at UC Davis, who’s an expert in invasion biology.

    However, there is disagreement about where the invasive flies the state keeps finding in traps are coming from.

    Carey argues that it’s likely the medfly has made itself at home here, in part, because they keep showing up in the same relative areas.

    But when I asked Jason Leather, the entomologist who oversees the fruit fly program, how likely it is that they’re established, he said, “I think it’s actually zero.”

    “Airline passengers are the biggest pathway for fruit flies into California," he added. "During the pandemic, air travel stopped and our traps were really empty."

    Again, Carey disagrees.

    “The only way you can monitor the wild population is by trapping. Well, guess what? The sterile flies also go to these traps,” Carey said. “It’s not entirely clear if it’s suppressing the populations or suppressing the detection. I would say it’s a little bit of both. But that’s a huge challenge for monitoring.”

    What is certain is that the program will continue for the foreseeable future. And that threats from other exotic pests like the oriental fruit fly need to be dealt with.

    If you'd like to help monitor for medflys, you can contact the CDFA and ask if they can put traps in your yard.

  • County health warns of possible exposure

    Topline:
    The Los Angeles County Department of Public Health is warning the public of a potential measles exposure from an unvaccinated individual who traveled through Union Station this month.

    Details: People at Union Station during the exposure window of 8 a.m. to noon on Sept. 12 may be at risk of contracting measles seven to 21 days after exposure, county health officials say.

    What's next: People who were at Union Station between those hours should monitor for symptoms until Oct. 3.

    Go deeper: There are already more US measles cases this year than in all of 2025

    The Los Angeles County Department of Public Health is warning the public of a potential measles exposure from someone who traveled through Union Station in Downtown Los Angeles earlier this month.

    What happened

    The unvaccinated passenger arrived at Union Station on Saturday, Sept. 12, by Amtrak train just after 7 a.m. and departed about four hours later on an Amtrak Thruway bus bound for Bakersfield.

    People at Union Station during the exposure window of 8 a.m. to noon may be at risk of contracting measles seven to 21 days after exposure. The last day to monitor for symptoms is Oct. 3.

    State health officials say the passenger was traveling on buses and trains through L.A. and at least five other California counties before leaving the state.

    "This case, along with previous measles outbreaks in California this year, serve as reminders of the importance of vaccination against measles," said Dr. Rita Nguyen, assistant state public health officer. "Measles is one of the most contagious infections that can lead to severe lifelong consequences, including permanent brain damage, and can also be fatal, especially for children."

    What to watch for

    Symptoms of measles include fever, red, watery eyes, and a rash that usually develops several days after other symptoms and typically starts on the face.

    As of Sept. 14, a total of 59 measles cases have been reported in California this year. In most cases, patients were unvaccinated or had unknown vaccination status.

  • A major project is reshaping 5 miles of Studebaker

    Topline:

    Long Beach is embarking on its biggest street redevelopment yet, reshaping over five miles of Studebaker Road into bike friendly lanes with other improvements.

    Why it matters: Long Beach has been working toward this vision since it adopted its bicycle master plan 25 years ago, now with mounting urgency as auto-related fatalities rise.

    Why now: The biggest project so far – the Studebaker Road Transformation Project – is bringing this vision to the doorstep of Studebaker Road residents. But not everyone is a fan.

    Imagine a sprawling network of roomy bike lanes, generously landscaped to calm relentless traffic. Think Amsterdam with newer buildings and fewer waterways. That’s been Long Beach’s goal anyway.

    Instead of wide post-war boulevards, roads would become slower and leaner, transforming Long Beach into a top-five global cycling city, said former city traffic engineer Paul Van Dyk. “Some of that is tongue-in-cheek, but if you shoot for the moon you land in the stars.”

    Long Beach has been working toward this vision since it adopted its bicycle master plan 25 years ago, now with mounting urgency as auto-related fatalities rise. The biggest project so far – the Studebaker Road Transformation Project – is bringing this vision to the doorstep of Studebaker Road residents.

    It has drawn mixed reviews.

    'The intent of the design is malicious'

    “The intent of the design is malicious — it’s immoral,” said Joey Schilling, who drives the road six days a week and wrote a social media post criticizing the project that drew almost 1,000 comments. ”It’s people who do not use the road trying to tell other people how to use the road.”

Cordova.The $65 million project runs over five miles from Second Street all the way up to Carson Street. It includes bike lanes, greenways and stonescape with fiber-optic cable running underneath. It is crucial to the city’s long-term plan of knitting together 300 miles of bikeways by 2040 to bring bicycle culture to Long Beach, as well as create safer streets.

    The massive project funded from 13 federal, state and local agencies, gives a glimpse of what’s to come for Long Beach thoroughfares. The Clark Avenue work is in progress. Pacific Avenue and Orange Avenue “backbone” plans are on deck. Now Studebaker Road, the biggest, longest and most expensive, is well underway, spending the most dollars and, arguably, drawing the most resident anger.

    Schilling, who lives near Studebaker Road actually does ride his bike to work in Seal Beach and said he is OK with bike lanes in general. However, he says the project is not practical in a community where he says most drive to work. “It’s not a reasonable solution. It’s not even for the greater good, that would be to appease the 95 percent who use their cars. The cost and the benefit do not match up. The cost is too high, the benefit too low.”

    Wider lanes, sturdier medians

    The Studebaker project features raised bus stops and wider bike lanes than have been seen previously. No more flimsy bollards separating bikes from cars, said Van Dyk, the city traffic engineer who helped usher in the bikeway and traffic-calming street plan before he went on to consult on other urban bike projects.

    The green bollards seen on Bellflower Boulevard and Studebaker before the redo often get hit by cars and can resemble thick blades of stomped grass. “People do not like the way they look, and I agree with their frustrations,” said Van Dyk. “That’s why we moved towards those concrete medians.“ He said planners “learned a lot of lessons along the way.”

    Studebaker will feature roomier bike lanes – 9 feet wide compared with the old 6-foot-across version. Wider lanes will allow riders to travel two abreast for a better ride, Van Dyk said. It also makes them easier to clean. Debris-filled lanes are a sore spot with bikers.

    The old bike lane sweeper the city used to clean narrow paths was notoriously difficult to move and use. (Fourth District Councilmember Daryl Supernaw joked that sightings of the small sweepers were less frequent than Bigfoot.) But a regular street sweeper can get into the broader lanes where it can’t on Broadway and Bellflower south of Atherton. (They actually set a street sweeper in a bike lane before planning and pouring the concrete to make sure it would fit.) Still, protected bike lanes are harder to clean than lanes merely separated by paint and “swept” by passing cars.

    David Raslevich, a 41-year-old cyclist who frequently rides on the new lanes on Clark, said he has noticed branches, leaves and other debris. “I feel safer riding with the traffic, because they (cars) move debris out of the way for you.”

    Buses stop in traffic, not turnouts

    One new component of Studebaker and the other newer lanes are raised bus stops. The new stops designed to accommodate bikes and buses are about five inches off the ground and separated from the road by a curb. Buses will stop in the No. 2 lane, halting traffic behind them, and pick up passengers, instead of easing out of a bus turnout.

    Van Dyk said that change evolved from talks with Long Beach Transit, which revealed that buses would sometimes get hit when pulling into traffic. Planners reasoned it’s better to have cars waiting for a bus to pick up passengers instead of forcing a bus waiting to pull into the No. 2 lane.

    “It’s math my second grader can do: What’s better, 40 people on a bus wait or four people in cars,” Van Dyke said. “Which is the greatest cost to society? The bus is going to be more efficient.” He also contends the new system is safe; there is less ambiguity as a bus will slow down in front of a car, so the car would be more likely to stop instead of zipping around a protruding bus bumper.

    It is too early to know how this plan will play out – the new bus lane curbs on Clark show missing chunks already from drivers that likely didn’t see them. Raslevich said he has seen cars turn into the curb by the raised bus stop. “They don’t know that there’s an island there, so they’re hitting that island, pretty much daily.”

    Councilman Supernaw, whose district encompasses the $65 million project, had reservations about the price tag before ultimately supporting it.

    'All anyone asked for is a repave'

    “All anyone asked for is a repave, to get rid of potholes and have a smooth surface to drive on,” Supernaw said. “Should we just forgo the bike lanes and do a straight repave? The answer was no, we wanna use the grant money for the bike lanes.”

    The city saw it as a grander vision, weaving together a puzzle of state and federal grants along with $8.5 million in local sales tax money for new transit stops, sidewalks and curb ramps that improve how all people can move through the city.

    “It’s not just ‘I wanna ride a bike for fun.’ People need it to get to work,” said Jocelin Padilla, a spokesperson for the city’s Public Works Department.

    'Communication via spraypaint'

    A series of community meetings were held in 2024, drawing limited feedback. But when residents later saw painted pavement markings showing the planned curbs and bike lines, “they got involved in a big way,” Supernaw said.

    “We call this communication via spraypaint,” said Supernaw. “Constituents see lines marked out and contact the council office.”

    Aside from the cost and the bus islands, some residents are frustrated by the execution. Leslie Goldman, who lives near Studebaker and Stearns, said large piles of dirt – at times higher than cars – have blocked residents from crossing the street or seeing oncoming traffic. Some concerns were addressed, including a bus shelter that was added due to feedback from residents.

    “We’re not saying we don’t want construction done ever, that’s life in the big city,” she said. But Goldman contends the “assembly line” construction approach, as opposed to the work done in shorter phases, is leading to more “noise, vibration, dust, traffic, blind spots, trash, roadblocks, … All at sporadic intervals unknown to residents. It’s not just an inconvenience, it’s a hardship.”

    A 'once-in-a-generation' timeline

    Padilla of Public Works acknowledged the hardship, but said the benefits would outweigh the short-term pain. She said doing the work in shorter segments would increase costs and project timelines – not a good thing when it needs to be finished by the Olympics. “This is a once-in-a-generation project,” she said.

    Not all residents are wary. “Studebaker is gonna be awesome when it’s done,” said Dan Olsen, who lives near Studebaker and Atherton. “It’s new, it’s fresh, the neighborhood is going to benefit. It’s been a total pothole disaster for so long. … Even though there are catches and hooks, it’s still worth it.”

    Long Beach still isn't Amsterdam

    Long Beach is not yet Amsterdam; it’s still a patchwork of protected lanes and unprotected ones of varying degrees of newness. But Studebaker should be done in 2027. Pacific Avenue and Orange Avenue are next. The bike lanes and streets won’t uniformly connect, but there will be more of them – Artesia Boulevard to service Jordan High, Clark Avenue near Long Beach City College and now Studebaker. “Long Beach’s cycling network is reaching critical mass,” Van Dyk said.

    Van Dyk and other bike proponents say it’s a long game. Amsterdam itself was car-dominated until the 1970s when the Stop de Kindermoord movement was launched in response to the high number of child deaths. “It’s a generational effort; it took multiple generations to give us the infrastructure we have today,” he said.

    Will any of this make the streets safer?

    Will they help make transportation safer for cars and bikes? The city racked up 53 traffic deaths in 2025, the highest in a decade, and 32 bike/pedestrian and e-scooter deaths. This year has seen 36 traffic deaths through mid-September. The city is also trying other tools; speed cameras are being installed, and tickets will go out this fall.

    It’s not yet any safer to ride through Long Beach than it was 10 years ago, “but it’s not safer to do anything in Long Beach,” said Kurt Canfield, a cyclist and organizer for Car Lite Long Beach, a bike advocacy organization. He often rides the Broadway bike path, which he considers a success despite debris in the lane and other issues.

    “They wanna bike, they wanna walk, people are driving 300 horsepower crossovers. We’re in conflict for the same space,” he said. “But this infrastructure gives us the ability to be safer.”

  • Two shows bring live music to Griffith Park

    Hunter Noack takes in the view at Summer Lake, Oregon, ahead of an In a Landscape performance.

    Topline:

    Pianist Hunter Noack brings his grand piano to Griffith Park for two shows in September, part of a nationwide series organized in partnership with the nonprofit Trust for Public Land.

    Why it matters: The Sept. 26 and 27 performances mark the first time the "In a Landscape" series has played Los Angeles in its 11-year run.

    Why now: The shows nod to Trust for Public Land's work in the Griffith Park hills. The nonprofit helped raise the funds that kept Cahuenga Peak and the ridgeline around the Hollywood sign from being developed.

    A grand piano, hauled in on a Ford F-350, will make its way next weekend to Griffith Park.

    Then, right below the Hollywood sign, the flatbed will unfold into a stage for a recital by pianist Hunter Noack, who has played everywhere from Yosemite Valley to Joshua Tree National Park.

    His Sept. 26 and 27 performances are all part of In a Landscape: Classical Music in the Wild, organized in partnership with the nonprofit Trust for Public Land. (The show is sold out, but you can sign up for the waitlist.)

    For a decade, Noack has hauled his Steinway — the same model used at Carnegie Hall — through rough terrain to perform in unusual places: 370 concerts and counting.

    The piano has survived fire, wind and 112-degree heat

    "We've had the piano lid be ripped off by the wind. We've had the piano trailer tires catch fire on Highway 1. We've almost driven off the side of Mount Bachelor. We've played in 112-degree heat and negative 2 degrees in the winter," Noack said. And the piano has come out unscathed, including after it was towed down the washboard gravel along Schweitzer Mountain in Idaho — the only thing that happened was that it went out of tune.

    How the show actually works

    Among the pieces on the program at Griffith Park is "Nature Boy," the song Eden Ahbez wrote while living outdoors under the first L of the Hollywood sign. The song was later made famous by Nat King Cole.

    Audiences at the Griffith Park show will be provided with wireless headphones for concert-hall quality sound, he said. "Some people just set up their picnic chairs or blankets right near the stage. Other people lay down," Noack said. "When there's so much else that's happening visually ... the music kind of automatically becomes a soundtrack, and we all get to experience that together."

    The philosophy behind the series' name

    The series is named after "In a Landscape," a piece by John Cage, who believed any sound could be music — even "somebody crinkling on a bag of chips," Noack said.

    During his first show in 2016 at the Columbia River Gorge, Noack was midway through a soft Schumann piece about a delicate flower when 40 Harley-Davidsons on a memorial ride rolled up and circled the piano.

    Rather than pack it in, he answered with Frederic Rzewski's "Winnsboro Cotton Mill Blues," a piece built to mimic the aggressive clatter of a cotton mill. "It was a conversation between the piano and these roaring Harleys," he said.

    In a Landscape: Classical Music in the Wild

    Where: Griffith Park, 3200 Canyon Dr., Los Angeles
    When: 3 to 4:30 p.m., Saturday, Sept. 26 and Sunday, Sept. 27
    Tickets: Both shows are sold out, but you can join the waitlist.

    California accounted for the largest share of ICE arrests involving people from Asian countries during the first 18 months of President Trump’s second term, according to a new data tracker.

    Why now: The new Asian and Pacific Islander ICE Tracker shows how arrests, detentions and deportations are rising faster among Asian immigrants than among immigrants overall.

    Go deeper: ICE raids quiet SoCal's Asian hubs

    California saw the largest share of immigration arrests of people from Asian countries during the first 18 months of President Trump’s second term, a new tracker shows.

    More than 25% of arrests by Immigration and Customs Enforcement agents took place in California, home to the country's largest Asian population, followed by Texas and New York.

    The findings come from the new Asian and Pacific Islander ICE Tracker launched by Stop AAPI Hate.

    These communities are often missing from the national debate over immigration enforcement, said Cynthia Choi, co-founder of Stop AAPI Hate during a briefing on the tracker.

    “Asian and Pacific Islander communities deserve better than to be an afterthought in this crisis," Choi said. With the tracker, "we are aiming to ensure we cannot be ignored any longer."

    The data shows that ICE actions targeting Asian immigrants rose much faster than enforcement against groups overall between January 2025 and August 2026.

    Arrests were up 436% compared to a similar time period during the Biden administration; detentions up by 512%; deportations up by more than 1,100%.

    The number of arrests peaked this past July with 1,950 recorded nationwide.

    In California, there have been more than 5,300 arrests of Asian immigrants and more than 11,400 detention stints, which includes separate stays at different facilities during a single detention.

    As for deportations, they were not broken down by state.

    The largest numbers involved people from India and China, the countries of origin for the largest Asian immigrant populations in the U.S.

    Stephanie Chan, Stop AAPI Hate’s director of data and research, noted that a rise in anti-Indian rhetoric centered on H1-B visa holders and truck drivers.

    "You see a lot of elected officials saying things like, 'Indians are coming to take the jobs,'" Chan said.

    Researchers also found that people from smaller communities — such as those from Laos and Uzbekistan — were arrested at rates far disproportionate to their share of the Asian noncitizen population.

    The tracker draws from ICE records obtained through public-records requests by the Deportation Data Project at UCLA and UC Berkeley.

    Leaders at Stop AAPI Hate said the Trump administration's immigration crackdown is not only harming the people being swept up by ICE. Chan said the group’s annual survey of Asian Americans and Pacific Islanders found more than half have felt the effects.

    “That includes things like fearing that their status will be questioned,” Chan said. “That they will be arrested, detained, or deported.”

    Choi drew parallels with how Asian Americans were scapegoated during the COVID-19 pandemic.

    U.S. Rep. Ro Khanna, a California Democrat who joined the briefing on the tracker, said the findings felt "very personal" because of the state’s large share of arrests.

    A member of the Republican-led congressional China Committee focused on U.S. competition with the Chinese government, Khanna predicted Democrats would win the mid-terms and shift the tone of that panel.

    "It's going to be much more about a celebration of Asian Americans — and documenting that — than the demonization of other countries," Khanna said.
