Conventional “free diffusion” model of steroid hormone release should be revisited, notes UC Riverside-led study; research could have health and agricultural benefits RIVERSIDE, Calif. – Steroid hormones – hormones such as testosterone and estradiol – control various aspects of animal biology and are crucial for the proper functioning of the body. Produced and secreted by...
By Richard Levine, Entomological Society of America RIVERSIDE, Calif. – Researchers at the University of California, Riverside might have found a breakthrough in the spider-control field. In a paper published in the Journal of Economic Entomology the researchers wrote that oil-based pesticides are more effective than water-based pesticides at killing the contents of brown widow...
By eliminating the queen, a matricidal worker frees the way for workers to lay male eggs, explains UC Riverside’s Kevin Loope RIVERSIDE, Calif. – One day a few years ago, while working on wasps in a rainforest in Costa Rica, entomologist Kevin J. Loope, a postdoctoral researcher at the University of California, Riverside, began reading...
Six graduate students in the Department of Entomology have received Robert van den Bosch Scholarships offered by the Center for Biological Control at UC Berkeley. The scholarships, which range from $5,000 to $20,000, may be used for graduate student salary, tuition and fees, laboratory help, supplies or travel for research. The six students are: Erich...
RIVERSIDE, Calif. – Despite their beauty, flowers can pose a grave danger to bees by providing a platform of parasites to visiting bees, a team of researchers has determined. “Flowers are hotspots for parasite spread between and within pollinator populations,” said Peter Graystock , a postdoctoral researcher in the Department of Entomology at the University...
RIVERSIDE, Calif. – The Entomology Research Museum at the University of California, Riverside today announced the discovery of a new species of firefly from Southern California, collected by an undergraduate student as part of his semester’s insect collection. Doug Yanega, senior museum scientist, said the student, Joshua Oliva, obtained one specimen of the new species...
RIVERSIDE, Calif. – Cockroaches are scientifically interesting to study. A primitive yet highly diverse group of insects, they live in a wide range of habitats—such as temperate habitats, tropical habitats, deserts, in the nests of birds and social insects, sewers and dumpsites—and exhibit a variety of reproductive strategies. They are also major pests. They can...
UC Riverside research shows house-dwelling mosquitoes require minute changes in concentrations of exhaled carbon dioxide to trigger landing on human skin RIVERSIDE, Calif. — Females of the malaria-spreading mosquito tend to obtain their blood meals within human dwellings. Indeed, this mosquito, Anopheles gambiae, spends much of its adult life indoors where it is constantly exposed...
UC Riverside research could lead to innovative strategies for controlling mosquito populations RIVERSIDE, Calif. – Diseases transmitted by mosquitoes have contributed to the death and suffering of millions throughout human history, earning the mosquito the title as the world’s most dangerous animal. Even today, several devastating mosquito-borne diseases (such as malaria, dengue fever and West...
