    Mosquito expert: Washington downplaying Zika virus threat to US

    As the number of birth defects linked to a mosquito-borne virus surpasses 4,000 in Brazil, and scientists scramble to create a vaccine to protect against the untreatable disease, public health officials are bracing themselves for a potential outbreak in the U.S. The threat has some advocacy groups pushing for tighter health screenings among travelers and immigrants from Zika-afflicted countries, while public health officials and tropical disease experts argue preparing to fight the Aedes aegypti, an insect that doesn’t respond to common pesticide, is more pressing. “First of all, I th...

    Researchers map bedbug genome by following pest through subway

    Researchers have mapped the genome of bedbugs in New York City, then traced fragments of the nefarious pests’ DNA through the subway system. The new work, led by researchers at the American Museum of Natural History and Weill Cornell Medicine, and published today in Nature Communications, could help combat pesticide resistance in the unwelcome parasite. The data also provide a rich genetic resource for mapping bedbug activity in human hosts and in cities, including subways. “Bedbugs are one of New York City’s most iconic living fossils, along with cockroaches, meaning that their outwa...

    So long, suckers: would it be safe to wipe out mosquitoes?

    A race is on to do something about the Zika virus. A possible vaccine is years away, so that means doing something about its vector, the Aedes aegypti mosquito. Genetic engineering techniques mean it is possible to conceive of obliterating this insect entirely. But would there be an ecological downside to exterminating a creature whose only purpose seems to be to bother us? As with many predictions involving complex natural systems, a definitive answer is impossible. Some ecologists worry about small changes having big unforeseen effects, and liken the complexity of ecosystems to that...

    Mapping the bedbug genome: Seeking clues to bite back against pest

    If you live in a city, the word "bedbug" is like an icy dagger to the heart. The blood-suckers rely on humans to survive, and they're great at hopping from one apartment (or person) to another. They're also increasingly resistant to insecticides. But don't pledge fealty to our mattress-dwelling overlords just yet: In a pair of papers published Tuesday in Nature Communications, two teams of researchers report the first ever complete genome sequencing for the pest. Sequencing an organism's genome - figuring out what genes it has and where they all go - makes studying it much, much easie...

    Insect Nicknames A word or set of words by which a person, animal, place or thing is known is a name. Exactly when humans began using names for each other is lost in antiquity. For sure, though, we have been using vocal utterances to describe things including each other for thousands of years. In western cultures a person’s name might be made up of two, three or sometimes even more words. Most of us have a first and a last name. Our first name is called a given name and the last name a family name. We might also have a middle name. At one time way back in human history individuals wer...

    Editorial: California is safer than most from Zika virus

    The warnings from the World Health Organization about the Zika virus are undeniably alarming. During the next year, as many as 4 million people in the Americas could be exposed to the mosquito-spread virus, which is linked to brain damage in infants and paralysis in adults. Cases have been reported in about two dozen countries, including the United States. Pregnant women are being warned to stay away from certain countries. But in California, there’s no need to “freak out,” Dr. Jorge Parada, medical adviser for the National Pest Management Association, told The Sacramento Bee’s Sammy ...

    Honeybee research could help prevent winter die-off

    Winters are tough on honeybees. Cold weather means no pollen for food, and hives can starve to death while pests and disease problems are amplified. In recent winters about one-third of all Virginia bee colonies have not survived to see spring. Virginia State Apiarist Keith Tignor is hoping his research on greenhouse bee farming could make a difference for many hives. “Prior to the introduction of pests like the trachea mite, varroa mite, small hive beetle and some of the diseases that have been introduced in the past 15 years, the winter losses were about 10 percent or even down to 5...

    Bedbugs develop resistance to widely used chemical treatments, rendering them ineffective

    Millions of dollars have been spent on insecticides to kill the bugs that have wreaked havoc on everything from hotels in New York City to homes in Los Angeles. But this is the first study to show that overuse of certain insecticides has led to an increased resistance to the compounds, making them much less effective than advertised. "While we all want a powerful tool to fight bed bug infestations, what we are using as a chemical intervention is not working as effectively it was designed and, in turn, people are spending a lot of money on products that aren't working," said Troy Anderson...

    Health official doubts Zika virus poses major threat to US

    WASHINGTON (AP) — A leading Obama administration health official says he doubts the United States is vulnerable to a widespread outbreak of a virus linked to a wave of birth defects in Brazil. Dr. Anthony Fauci says the Zika virus — suspected of being connected to microcephaly — hopefully can be kept at bay with “mosquito vector control.” Fauci, who heads the National Institute of Allergy and Infectious Disease, appeared on “CBS This Morning.” He tells interviews administration officials do not believe there are major ways of spreading the virus “other than by mosquito bites.” Heal...

    Home warmth wakes up the insects

    The mid-January thaw we experienced recently brought some unwanted visitors to local homes. By far the most calls were from people who burn firewood. As wood warms, the critters that feed on decaying wood or the creatures that feed on those insects can wake up from their winter slumber and begin moving about. If that firewood is indoors, the insects can become nuisance pests. There are several different types of insects that are commonly found on firewood. Wood boring beetles, including the flat headed borer, long horn beetles and bark beetles are the most frequently reported. None of t...

    Scientists determine how to control parasite without harming bees

    The parasitic mite Varroa destructor (varroa) is generally agreed to be the greatest threat facing honey bees worldwide. Despite much research, losses continue due to lack of effective control measures, because the mite has become resistant to several commonly used chemicals. The natural product oxalic acid has been widely used in mainland Europe but surprisingly little previous research has directly compared different methods of application, their efficacies, and their adverse effects on bees. In a paper published in the Journal of Apicultural Research, Hasan Al Toufailia, Francis Ratni...

    Pest-Control Services: Why Self-Storage Operators Should Leave It to the Pros

    By Jim Fredericks and Cindy Mannes Owners of self-storage facilities work hard to maintain high business standards and ensure customers’ possessions are protected from theft, damage and exposure to the elements. Some of the safeguards put in place, including pest-control services, are an ongoing expense to maintain clean and safe conditions. As owners scrutinize their budget and operation costs, some may wonder whether they should invest in professional pest-control services or attempt a do-it-yourself approach. While it may be tempting to handle things on your own, pest control shoul...

    How to keep away mosquitoes carrying Zika, dengue

    (CNN)When Zika virus made headlines because of its link with the neurological disorder microcephaly, it became the latest in a growing list of mosquito-borne viruses for Americans to worry about. "Dengue, chikungunya and Zika are the ones that I'm very fearful of for the Gulf Coast states [such as Florida and Texas], and Zika is the most terrifying of all because of the horrific birth defects," said Dr. Peter Jay Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine. There have been several dengue outbreaks in Texas, Florida and Hawaii over the last sev...

    Canadian feds tighten pesticide control rules

    OTTAWA – The federal government is responding to calls from environmental activists over conditionally approved pesticides, saying it will end the rare practice of allowing the use of pesticides that aren’t fully approved for sale. Health Minister Jane Philpott says conditional registrations of the chemicals will no longer be granted, effective June 1. Two separate House of Commons committees and Canada’s environment commissioner had called on the government to end the practice of allowing some pesticides to be used while the products undergo a more rigorous scientific evaluation. ...

    New Nest Box Study Revolutionizes Using Barn Owls for Rodent Control

    SACRAMENTO, Calif., Jan. 20, 2016 /PRNewswire/ -- Imagine owning a machine that swoops over your property while you sleep and removes thousands of rodent pests per year. What's more, it needs little maintenance and does it at a fraction of the cost of poisoning or trapping. Just such a machine is the barn owl, especially when used in a well-designed nest box program such as the one created by biologist Mark Browning near Elk Grove, California. "Our goal was to determine how dense of a population of owls we could attract, and how that population would affect the numbers of rodent pests," ...
