A Closer Look: Argentine Ant Control

Research out of UCR finds that even though Argentine ant control is labor intensive, the use of various formulations of perimeter sprays and baits may help reduce treatment times for PMPs. Pest and Diseases Image Library, Bugwood.org Editor’s note: This research was conducted by the University of California, Urban Entomology Laboratory. Syngenta provided financial support...

New lab is California’s best defense against deadly citrus disease

California citrus growers and the University of California, Riverside have joined forces to open a research lab to defeat a disease that has decimated citrus crops in Florida and China. The disease, Huanglongbing, or HLB, is caused by bacteria spread by a tiny insect called the Asian citrus psyllid. HLB prevents fruit from ripening properly,...

Entomologists in the field wage war on a potential agricultural threat

A team of entomologists from UC Riverside is on a mission to save California’s wine, nuts and avocados from an insect on the move. Follow them as they hunt in the highest mountains of the Southwest for an elusive native fly that’s key to controlling the pest. https://www.youtube.com/watch?v=ah2SKqPeel0


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 can live for many years...

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. The pest, a sap-sucking spotted lantern fly, is originally from China and was first detected five years ago in Pennsylvania. Since then, large populations have spread rapidly to grape vines, apple...

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 student interest in crime scene...

Bee mite arrival in Hawaii causes pathogen changes in honeybee predators

The reddish-brown varroa mite, a parasite of honeybees and accidentally introduced in the Big Island of Hawaii in 2007-08, is about the size of a pinhead. Yet, its effects there are concerning to entomologists because the mite is found nearly everywhere honeybees are present. A team led by entomologists at the University of California, Riverside,...

Researchers identify new approach for controlling dengue fever and Zika virus

Mosquitoes are the world’s deadliest animals, killing thousands of people and causing millions of illnesses each year. To be able to reproduce and become effective disease carriers, mosquitoes must first attain optimal body size and nutritional status. A pair of researchers at the University of California, Riverside, have succeeded in using CRISPR-Cas9 , a powerful...
