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

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.
Buzzkill?
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...
In sexual conflict, ant queens prevail in evolutionary arms race
It’s hidden from sight, but there’s an epic battle of the sexes raging in the leafcutter ant species Atta colombica. Competing males deliver sperm in a fluid that’s toxic to rivals’ sperm, while females quash their efforts in order to ensure their own reproductive success. For the first time, a...
Looming insect invasion threatens California wine and avocados
UC Riverside is testing whether a sesame seed-sized wasp can control a pest that could seriously damage California crops including wine, walnuts, and avocados.
For the love of caterpillars
A first-generation student’s journey into entomology.
As bumblebee diets narrow, ours could too
There has been a lot of buzz about honeybees’ failing health because they pollinate our produce. Less well known is how critical bumblebees are for some of our favorite foods. And their numbers are also rapidly declining. A new study from the University of California, Riverside, reveals the loss of...
Maggots and murder: what insects can teach us about crime
Taking care to stand upwind, UC Riverside students display stoic professionalism as they collect insects off a pig carcass in 90-degree heat. This scene from a class in forensic entomology could have been ripped from any TV police drama and in some ways, it was. Professor Alec Gerry said intense...
Superbloom? If you say so
Superbloom is a term concocted by the media, but this year’s wildflowers are still spectacular, especially for the creatures that depend on them
Bee mite arrival in Hawaii causes pathogen changes in honeybee predators
UC Riverside-led research, done on the Big Island, shows effects of mite introduction have cascaded through entire pathogen communities

Researchers to Target Mosquito Egg Production to Curtail Disease
RIVERSIDE, Calif. — Entomologists at the University of California, Riverside have received a five-year grant of $2.44 million from the National Institute of Allergy and Infectious Diseases, or NIAID, to investigate the role hormones play in the female mosquito’s ability to use human blood for egg production. Vector mosquitoes need...
