    The flowers that give us chocolate are ridiculously hard to pollinate

    It’s a wonder we have chocolate at all. Talk about persnickety, difficult flowers.

    Arguably some of the most important seeds on the planet — they give us candy bars and hot cocoa, after all — come from pods created by dime-sized flowers on cacao trees. Yet those flowers make pollination just barely possible.

    Growers of commercial fruit crops expect 50 to 60 percent of flowers to...

    Grapevines are more drought-tolerant than thought

    The latest word on the grapevine is promising.

    During more than a decade of observation, grapevines in Napa, Calif., and Bordeaux, France, never reached lethal levels of dehydration from seasonal drought, researchers report online January 31 in Science Advances. Plant ecophysiologist Guillaume Charrier, at the French National Institute for Agricultural Research in Paris, and colleagues...

    Gassy farm soils are a shockingly large source of these air pollutants

    California’s crops are creating some noxious air.

    The Golden State is at the vanguard in the United States in reducing auto emissions of nitrogen oxide gases, which help produce toxic smog and acid rain. But the NOx pollution problem isn’t limited to auto exhaust. California’s vast agricultural lands — particularly soils heavily treated with nitrogen fertilizers — are now responsible for...

    The mystery of vanishing honeybees is still not definitively solved

    It was one of the flashiest mysteries in the news about a decade ago — honeybee workers were vanishing fast for no clear reason. To this day, that puzzle has never been entirely solved, researchers acknowledge.

    And maybe it never will be. Colony collapse disorder, or CCD, as the sudden mass honeybee losses were called, has faded in recent years as mysteriously as it began. It’s possible...

    Honeybees fumble their way to blueberry pollination

    DENVER — Honeybees may be the world’s most famous pollinator, but a new study shows that blueberry blooms reduce the insects to improvisational klutzes. Not useless ones though.

    Pollination specialists have realized that the pollen haul found in hives of Apis mellifera honeybees has little, if any, from blueberry flowers, ecologist George Hoffman said November 5 at the Entomology 2017...

    EPA OKs first living pest-control mosquito for use in United States

    In a big step toward catching up with the rest of the world, the United States cleared the way for using mosquitoes as a commercial pest control for the first time.

    The U.S. Environmental Protection Agency has approved using a strain of male Asian tiger mosquitoes (Aedes albopictus) as a biopesticide in the District of Columbia and 20 states, including California and New York. Kentucky-...

    Much of the world’s honey now contains bee-harming pesticides

    Neonicotinoid pesticides are turning up in honey on every continent with honeybees.

    The first global honey survey testing for these controversial nicotine-derived pesticides shows just how widely honeybees are exposed to the chemicals, which have been shown to affect the health of bees and other insects. Three out of four honey samples tested contained measurable levels of at least one...

    José Dinneny rethinks how plants hunt for water

    José Dinneny, 39Plant stress biologistCarnegie Institution for Science 

    José Dinneny wants us to see plants as stranger things.

    “They’re able to integrate information and make coherent decisions without a nervous system, without a brain,” he points out. Plus, plants find water without sight or touch. For too many of us, however, lawns, salads and pots on a sunny windowsill make...

    ‘Big Chicken’ chronicles the public health dangers of using antibiotics in farming

    Big ChickenMaryn McKennaNational Geographic, $27

    Journalist Maryn McKenna opens Big Chicken by teasing our taste buds with a description of the succulent roasted chickens she bought at an open-air market in Paris. The birds tasted nothing like the bland, uniform chicken offered at U.S. grocery stores. This meat had an earthy, lush, animal flavor. From this tantalizing oh-so-European...

    GM moth trial gets a green light from USDA

    Cabbage-chomping moths genetically modified to be real lady-killers may soon take flight in upstate New York. On July 6, the U.S. Department of Agriculture OK’d a small open-air trial of GM diamondback moths (Plutella xylostella), which the agency says do not pose a threat to human or environmental health.

    These male moths carry a gene that kills female offspring before they mature....
