Danish researchers have addressed an international environmental problem by developing a model that can predict how certain chemicals amplify the effects of pesticides and other chemical compounds. Pesticide expert hopes that it will make environmental legislation easier.
Xanthones are specialized metabolites with antimicrobial properties that are found in the roots of medicinal plants called Hypericum perforatum, also known as St. John's wort.
The honey bee gut is colonized by specialized bacteria that help digest components of the floral pollen diet and produce molecules that likely promote bee health. In a study publishing Dec. 12, in the open access journal PLOS Biology, a group of researchers led by Philipp Engel at the University of Lausanne and ETH Zürich, Switzerland, have uncovered which bacterial species perform which specific digestive functions in the bee gut.
Farmers are stuck. Western corn rootworm can destroy cornfields -- and profits -- but populations of the 'billion-dollar bug' have stopped responding to insecticides and the genetically modified corn hybrids designed to resist insect attacks. But there may be hope. In a new study, University of Illinois researchers uncover the genetic basis of resistance to western corn rootworm, paving the way for development of non-GM corn hybrids that can withstand the worm.
Researchers at the University of California, Riverside have found a way to access and manipulate taste neurons in the pharynx (throat) of the common fruit fly that could help control the spread of mosquito-related illnesses, such as dengue, malaria, yellow fever, and Zika virus, and reduce the loss of crops due to agricultural pests.
Scientists from Pakistan's F Quaid-i-Azam University and Lancaster University have evaluated the organophosphate pesticide concentration in dust from farms and also from pesticide manufacturing plants in the megacity of Lahore. The results show dust in and around Lahore contains pesticide pollution that is a high health risk to all groups tested.
Since the 2005 ban of methyl bromide by federal regulators, winter strawberry growers have had limited options for managing broadleaf weeds, grasses and nutsedge species. But new research featured in the journal Weed Technology shows drip-applied herbicides may help to fill the gap.
Cattle, swine and poultry contribute a hefty portion to the average American's diet, but raising all this livestock comes at a cost to the environment: The industry produces a lot of methane, a potent greenhouse gas. Just how much gas the animals release, however, is the subject of debate. Now, one group reports in ACS' journal Environmental Science & Technology that a new approach could shed light on how accurate current data are.
Water presents a problem to cranberry producers. Phosphorus leaves the cranberry farm when water drains from the flooded fields. Researchers are looking into ways to reduce this runoff.
The western corn rootworm continues to be on the rise in Europe. Why attempts to biologically target this crop pest by applying entomopathogenic nematodes have failed, can be explained by the amazing defense strategy of this insect. A new study shows that the rootworm larvae are able to sequester plant defense compounds from maize roots in a non-toxic form and can activate the toxins whenever they need them to protect themselves against their own enemies.
