Most Microbes in Hummingbird Feeders Do Not Pose Health Hazard

Feeders or Flowers? Researchers Compare Microbes

Many people set up hummingbird feeders in their yards to nurture and watch these high-energy pollinators. But could the sugar water they provide be impacting these tiny feathered friends?

A study led by the University of California, Davis, is one of the first to address the potential for sugar water from hummingbird feeders to act as a vector for avian — or even zoonotic — pathogens. It found that the majority of microbes growing in feeders do not likely pose a significant health hazard to birds or humans.

Entomology and Nemotology

The Department of Entomology at UC Davis began as an offshoot of the Department of Entomology and Parasitology at UC Berkeley. Entomology at Davis was closely entwined with the department at Berkeley for more than 50 years before it separated and became autonomous. Much of this early record is fascinating and it demonstrates how entomology has always been an integral part of teaching, research and extension on the Davis campus—in effect the department and the campus came of age together.

Diversity as Natural Pesticide

Farms with more variety of crops attract fewer insect pests

Left to its own defenses, a farm field growing a variety of plants tends to attract fewer insect pests than a field growing just one type of crop. While scientists and farmers have noted that difference for years, the reasons behind it have been poorly understood.

Turning food waste into healthy soil

UC Davis helps study “fork-to- farm” fertilizer

A Sacramento company that turns food waste into liquid fertilizer has launched a three-year almond trial at UC Davis to test the product’s effect on crop production, nitrogen leaching, and soil health.

Working with Professor Edwin Lewis with the UC Davis Department of Entomology and Nematology, California Safe Soil is also conducting ongoing trials throughout the state with several other commodities, including berries, lettuce, and tomatoes.
