195 ways to help California’s painted ladies
By documenting hundreds of new nectar plants for painted ladies, scientists have renewed hope these charismatic butterflies may prove resilient to climate change.
Chemical cocktail in skin summons disease-spreading mosquitoes
A UC Riverside-led team discovered the exact chemical combination that causes Zika, dengue and yellow fever-spreading mosquitoes to locate and land on their victims.
The scent that could save California’s avocados
UC Riverside scientists are on the hunt for a chemical that disrupts “evil” weevils’ mating and could prevent them from destroying California’s supply of avocados.
Cousin of crop-killing bacteria mutating rapidly
A bacterial species closely related to deadly citrus greening disease is rapidly evolving its ability to infect insect hosts, and possibly plants as well.
Scientists fail to locate once-common CA bumble bees
Several species of California bumble bees have gone missing in the first statewide census of the fuzzy pollinators in 40 years. If they can be found, a recent court ruling could help save them.
Genetic discovery could spell mosquitoes’ death knell
A UC Riverside genetic discovery could turn disease-carrying mosquitoes into insect Peter Pans, preventing them from ever maturing or multiplying.
When bees get a taste for dead things
Typically, bees don’t eat meat. However, a species of stingless 'vulture' bee in the tropics has evolved the ability to do so, presumably due to intense competition for nectar. UC Riverside scientists find these bees' guts resemble those of hyenas and other carrion feeders.
Rising temperatures overcook bumblebees’ brunch
Bumblebees pollinate many of our favorite foods, but their own diet is being upset by climate change, according to a new UC Riverside study.
Hummingbirds can smell their way out of danger
In less time than it takes to read this sentence, hummingbirds can catch a whiff of potential trouble. That’s the result of new UC Riverside research showing, contrary to popular belief, the tiny birds do have an active sense of smell.
Study shows common insecticide is harmful in any amount
A new UC Riverside study shows that a type of insecticide made for commercial plant nurseries is harmful to a typical bee even when applied well below the label rate.
Cicada explosion mystifies insect experts
Doug Yanega, senior scientist at UC Riverside’s Entomology Research Museum, discusses one of nature's unsolved mysteries: the 17-year life cycle of cicadas in the Eastern U.S.
Scientists developing new solutions for honeybee colony collapse
The University of California, Riverside, is leading a new effort to stop and reverse a worldwide decline in honeybees, which threatens food security and prices.
UCR Citrus Gifts expands online with citrus and honey-infused marmalades, soaps, and more
The fruits of UC Riverside’s research are even easier to enjoy with the Citrus Gifts collection expanding its line of products and making them available online. The collection, featuring marmalades and olive oils from citrus and bee research, have been sold in campus stores for about six years. In June...
Scientists unlock genetic secrets of wine growers’ worst enemy
Following a decade-long effort, scientists have mapped out the genome of an aphid-like pest capable of decimating vineyards. In so doing, they have discovered how it spreads — and potentially how to stop it. The research team’s work on the genome was published this past week in a BMC Biology...
Parasite infestations revealed by tiny chicken backpacks
Blood-feeding livestock mites can be detected with wearable sensor technology nicknamed “Fitbits for chickens.” To help farmers detect mite infestations, a team of entomologists, computer scientists, and biologists led by UC Riverside entomologist Amy Murillo has created a new insect detection system. The team’s work is detailed in the journal...
Does urbanization homogenize regional biodiversity in native bees?
First survey of California’s bees in 50 years will look for effects of habitat destruction
Flower faithful native bee makes a reliable pollinator
Just like us, the humble sweat bee has a daily routine
Sugar-poor diets wreak havoc on bumblebee queens’ health
UC Riverside study shows that without adequate sugar, a bumblebee queen’s fat body, which functions like a human liver, does not correctly produce enzymes required for healthy metabolism and detoxification from pesticides.
Scientists short-circuit maturity in insects, opening new paths to disease prevention
New research from UC Riverside shows, contrary to previous scientific belief, a hormone required for sexual maturity in insects cannot travel across the blood-brain barrier unless aided by a transporter protein. The finding may soon allow scientists to prevent disease-spreading mosquitoes from maturing, or to boost reproduction in beneficial bumblebees.
They say love is blind, but if you’re a queen honeybee it could mean true loss of sight. New research finds male honeybees inject toxins during sex that cause temporary blindness. All sexual activity occurs during a brief early period in a honeybee’s life, during which males die and queens...
