Results help inform best practices for managing the disease-causing beetle
The University of California, Irvine campus is home to a vast urban forest consisting of approximately 30,000 trees located in a mix of landscape, riparian and open space settings. In the mid-2010s, that forest came under threat from an invasive species of beetle that arborists and pest researchers were just learning about – the polyphagous shothole borer.
The tiny beetles, which may have arrived in California from their native Southeast Asia via infested shipping materials, tunnel into trees and introduce a fungus that serves as food...

Last month, a California grape farmer was fined $10,000 for using a pesticide in violation of the label, then packing and attempting to sell the tainted fruit. DPR detected the residues of a pesticide on the produced that was not registered for use on grapes.

Various insects, birds and other animals pollinate plants. Bees, especially honey bees, are the most vital for pollinating food crops. Many California crops rely on bees to pollinate their flowers and ensure a good yield of seeds, fruit and nuts. Pesticides, especially insecticides, can harm bees if they are applied or allowed to drift to plants that are flowering.
Our mission at the University of California Agricultural and Natural Resources (UC ANR), Statewide Integrated Pest Management Program (UC IPM) is to protect the environment by reducing risks caused by pest management practices. UC IPM developed

Wildlife and people have been in the news lately. Perhaps you've heard of coyotes wandering in urban neighborhoods. You might have also read why you shouldn't feed wildlife. Did you know they are connected? It's a problem when people feed coyotes either intentionally or unintentionally by leaving garbage uncovered or pet food outdoors. Readily available food may encourage coyotes to lose their natural fear of humans. These interactions will be discussed during a symposium on urban coyotes at the 27th Vertebrate Pest Conference, March...
