A downy mildew caused by the oomycetous fungus, Peronospora mesembryanthemi Verwoerd has recently been confirmed by the USDA -APHIS from a red apple ice plant sample collected in San Diego. Since its first finding in San Diego County last summer, the disease has spread to Orange, San Bernardino, and Ventura counties and is now found in the Goleta area in Santa Barbara County. Peronospora mesembryanthemi was first reported from South Africa (Verwoerd, 1924) and later in the United Kingdom (Francis and Waterhouse, 1988) and New Zealand (McKenzie and Dingley, 1996), but has never been reported in North America. The host range of P. mesembryanthemi is thought to be limited to ice plants and it is currently found infecting the red apple ice plant, Aptenia cordifolia and the trailing ice plant or the pink carpet,Delosperma (syn. Mesembryanthemum) cooperi in California. Both these ice plant species are native to southern Africa. Because of their environmental hardiness, ease of growing, and bright, colorful flowers, ice plants are grown as ornamental plants or found as groundcovers. However, the red apple ice plant is listed as an invasive plant by the California Exotic Pest Plant Council. It can sometimes grow like a weed.

So this is National Invasive Species Awareness Week (February 21-27, 2016) [also see ] and it looks like there's a new pest in town. Hello Malaysian Fruit Fly. Hopefully we will say goodbye soon. You can see some information about it here.
Subject: APHIS Establishes Malaysian Fruit Fly (Bactrocera latifrons) Regulated Area in Westchester, Los Angeles County, California
Effective January 8, 2016, the Animal and Plant Health Inspection Service (APHIS) established a Malaysian fruit fly regulated area in Westchester, Los Angeles County, California. APHIS is applying safeguarding measures and restrictions on the interstate movement or entry into foreign trade of regulated articles from this area. This is the first continental U.S. quarantine for this species.
APHIS is responding to this confirmed detection with the establishment of a new regulated area, which encompasses approximately 74 square miles of Los Angeles County.
The Malaysian fruit fly, also known as the Solanum or Solanaceous fruit fly, is an economically important insect pest of plants of the nightshade family (Solanaceae). The fly is a native of south and southeast Asia. It has been found in the west African countries of Tanzania and Kenya, and it was first detected in Hawaii in 1983. The Malaysian fruit fly is primarily associated with wild and cultivated crops such as peppers, tomatoes, eggplant, and cucurbit species. This outbreak is considered to be transient, actionable, and under eradication.
APHIS is working with the CDFA, and the Agricultural Commissioner of Los Angeles County to respond to this detection following program survey and treatment protocols. This action is necessary to prevent the spread of Malaysian fruit fly to noninfested areas of the United States.
The establishment of this regulated area is reflected on the following designated website, which contains a description of all the current federal fruit fly regulated areas:

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 Vertebrate Pest Conference.
Special symposia include bird management, wild pig management, and urban coyotes. In Cooperative Extension Advisor Niamh Quinn's backyard of extremely urban Southern California, these coyote-human conflicts occur. With over 3 million people in Orange County, 8 state parks and beaches, countless city parks and 19 county parks and wilderness areas, conflicts with urban coyotes are bound to happen. Managing coyotes includes managing people's behavior too.
Quinn says, “We can't manage what we can't measure. This conference provides a unique opportunity to discuss ongoing conflicts, especially those related to urban coyote management. Research is needed to understand urban coyote behavior and if these behaviors are changing as a result of the way we are currently living. Outreach is needed to instruct urbanites on appropriate behavior where coyote conflicts are occurring, and managing coyotes is everyone's concern. We need better and improved strategies for measuring and managing these conflicts.” At the Vertebrate Pest Conference, hear from the experts on the latest information about coyote attacks on humans, coyote conflicts, and several talks on coyote management, including hazing.
Vertebrates are also problematic in commercial agriculture. A 2011 survey of wildlife damage by Cooperative Extension Specialist Roger Baldwin, stated agricultural losses from wildlife damage in California is likely in excess of $1billion annually. Based on the survey results, economic losses were greatest for voles and pocket gophers in alfalfa; and wild pigs, birds, and ground squirrels in nut crops. One talk at the Vertebrate Pest Conference will be a North American overview of bird damage in fruit crops. Other talks cover field rodent repellents, food safety, and trapping.
