Survey of professional bed bug management in multi-unit housing
Bed bug management is especially challenging in multi-unit housing (MUH) situations such as public and low-income apartment buildings. In these environments, high resident turnover, lack of resources, ease of bed bug dispersal, and communication barriers may all contribute to chronic infestations.
Researchers and policymakers recognize the need to address this challenging...

Wildlife and people have been in the news lately. Perhaps you've heard of coyotes wandering in your neighborhood. You might have also read about how you shouldn't feed wildlife. Did you know they are connected? It's a problem when people feed coyotes either intentionally or unintentionally through uncovered garbage and outdoor pet food. Available food may encourage coyotes to associate closely with humans and to lose their natural fear of us. These interactions will be discussed during a special symposium on urban coyotes at the 27th...

Did you know that every 60 days, California gains a new and potentially damaging invasive species? Once established, invasive species are extremely difficult to eradicate and can cause not only ecological disruption, but economic problems as well.
This week (February 21-27) is National Invasive Species Awareness Week. The goal of the week is to raise awareness and identify solutions to invasive species.
What is an invasive species? The term “invasive” is often used to describe something that appears to be taking over a garden or landscape. However, according to the National Invasive Species Council, a true invasive species is...
Goldspotted oak borer. First identified in eastern San Diego County in 2004, the goldspotted oak borer, Agrilus auroguttatus, has killed over 25,000 California native red oaks since its arrival and has now been detected in Riverside County. Larvae feed deep within the phloem, and adults are rarely seen. Infestations are recognized by the presence of D-shaped exit holes on trees, often accompanied by bark staining and crown decline. There are currently no good ways to manage the pest in moderate to severely infested trees. Contact your agricultural commissioner if you find infestations outside the known infested area.
For more information on this pest, infestation zones, and ways you can help limit the...
Today's post for National Invasive Species Week highlights two ambrosia beetles that are detrimental to certain trees. Ambrosia beetles are highly specialized beetles that excavate tunnels in usually weakened or dead trees and cultivate fungal gardens, which they feed upon. Below are two such invasive beetle-fungal complexes that are currently impacting trees and forests in California.
Walnut twig beetle and thousand cankers disease. Walnut twig beetle, Pityophthorus juglandis, is a tiny bark beetle that attacks only walnut trees. The beetle has been in California for many decades but recently became associated with a new fungus, Geosmithia morbida. The fungus kills the phloem and cambium of...
