The Bagrada bug, Bagrada hilaris, a colorful stink bug much smaller than the brown marmorated stink bug, prefers to feed on crucifers. It is a seed and bud feeder that can be very damaging to cole crop vegetables such as broccoli and cauliflower. In the landscape it can become very abundant on alyssum, stock, candy tuft, and mustards. The best strategy for landscapes infested with this pest is to replace alyssum and other hosts with alternative plants that it does not feed on.
In the United States, the bagrada bug was first found in Los Angeles County in 2008. By 2011, the pest had disseminated throughout Southern...
The brown marmorated stink bug (Halyomorpha halys) or BMSB is a new invasive pest of urban and suburban homes and landscapes in California.
A native of Asia, the brown marmorated stink bug immigrated into the United States in the 1990s but has only recently been reported in California. The bug prefers to feed on seeds and fruits, so is most damaging to fruit crops; however, it is a polyphagous feeder that may feed on fruit, leaves, or seeds of many ornamental plants as well.
Landscape managers may become most aware of this new pest in the fall when it aggregates in very large numbers on trees or within dwellings, often becoming a nuisance pest.

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...

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...

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...
