USDAgov posted a photo:

Citrus greening, one of the most significant citrus diseases, was first detected in Florida in 2005. The disease is now distributed throughout Florida and portions of South Carolina, Louisiana, Georgia, and Puerto Rico. Citrus greening is spread by the Asian citrus psyllid (ACP), its insect vector. ACP is widely dispersed in the United States, including Texas, Louisiana, Mississippi, Alabama, Georgia, Florida, Hawaii, and the Territories of Puerto Rico and Guam, as well as areas of Southern California and Arizona.

Gypsy Moth

USDAgov posted a photo:

Gypsy Moth—the European and Asian gypsy moths (AGM) are significant pests of trees and pose a major threat to U.S. forestry and natural resources. The European gypsy moth, first discovered in 1869 has more than 250 known host plants; AGM, which is not present in the United States, has a much broader host range, attacking more than 500 species of trees and shrubs. Overall control and management programs cost approximately $8.3 million (including USDA and State cooperators. Of this, APHIS directly contributes $4.9 million) per year and generate benefits that exceed $13.5 million.

The cooperative efforts of the Federal/State Gypsy Moth Program have reduced the spread of this pest from a historical average of 13 miles per year down to just 3 miles per year. This reduced spread rate will prevent the infestation of more than 150 million acres over the next 20 years.

Plum Pox Virus

USDAgov posted a photo:

Plum Pox Virus (PPV)—most devastating disease of stone fruits (plum, peach, cherry and apricot) worldwide; spreads via nursery stock, grafts and budwood of infected plants. The disease is transmitted from tree to tree by feeding aphids. The disease was first detected in the United States in a Pennsylvania peach orchard in 1999 and in New York in 2006. The overall eradication program cost approximately $4 million per year (of that APHIS provides approximately $3 million). After a 10 year eradication program, Pennsylvania was declared to be free of the disease in October 2009. The establishment and unmitigated spread of PPV in the United States could not only jeopardize the nearly $1.4 billion U.S. stone fruit industry, but also diminish commercial nursery production and residential stone fruit yields and quality, as well.

UG99 (wheat stem rust)

nobody@flickr.com (USDAgov) — Tue, 10 Aug 2010 03:27:20 -0700

USDAgov posted a photo:

UG99 is a new race of the wheat stem rust pathogen and highly virulent to wheat varieties worldwide. This race is currently spreading across eastern Africa, causing severe crop losses in some locations. The disease most recently spread into the Middle East and is causing major concern due to the large acreage of wheat planted with susceptible cultivars and the large numbers of people dependent on wheat for sustenance. Scientists are working on breeding varieties of wheat that are resistant to UG99. However, wheat is grown in a broad range of environments. This means that breeding programs would have extensive work remaining to get resistance into regionally adapted germplasms even after resistance is identified. The establishment and unmitigated spread of UG99 in the United States would jeopardize U.S. wheat production of 1.4 billion bushels per year, worth approximately $10 billion at the farm gate and 4.2 million acres of barley production worth $500 million per year.

Protecting U.S. grains production from Ug99 will require the development of around 100 new varieties of wheat and barley. Management of Ug99 epidemic in the U.S. would require millions of dollars in fungicide application. In FY10, the ARS estimated funding for Cereal Rust research is $4,839,600. APHIS provides $45,000 per year to ARS for screening the varieties.

USDAgov posted a photo:

Beetle Damage. Western bark beetles are not invasive (native) in western U.S. forests. However, severe drought and unhealthy forest conditions over the last decade, along with unseasonably warm winters have led to extensive pine tree mortality throughout the west, especially in Colorado, Wyoming, and Montana. Two species of bark beetles—the mountain pine beetle and spruce beetle—are particularly active. In 2009, the mountain pine beetle impacted 8.8 million acres, of the total 10.2 million acres affected by western bark beetles in the United States.

Although the infestation is too widespread to successfully control the beetles, the Forest Service and affected State partners work to protect high priority areas like recreational areas, water
sources and ecologically significant areas.

In FY 2010, the FS will spend $79 million for research, prevention, and suppression activities in an effort to reduce the impacts of western bark beetles.

APHIS does not regulate these pests due to their native status, but is currently developing regulations involving restrictions on the domestic movement of firewood and wood packaging materials in order to prevent the artificial spread of many forest pests, including the western bark beetles.

European Grapevine Moth

nobody@flickr.com (USDAgov) — Tue, 10 Aug 2010 03:27:27 -0700

USDAgov posted a photo:

A pest of economic importance to grapes, which is second largest crop grown in California, with an annual gross production value of $3.9 billion (USDA NASS 2009). Since first detected in California in the fall of 2009, APHIS spent approximately $5 million in support of the program. Based on its status as a significant grape pest in other parts of the world, the establishment of the European Grapevine Moth (EGVM) in California would result in significant production and export issues for grapes. Establishment could also result in a lesser export issue for some of EGVM’s other fresh market agricultural and nursery host plants. Photo Credit: Photo by Marc Epstein, CDFA.

Potato Cyst Nematode

nobody@flickr.com (USDAgov) — Tue, 10 Aug 2010 03:27:23 -0700

USDAgov posted a photo:

Potato cyst nematodes are invasive root-infesting pests of potatoes and tomatoes that are native to South America and widely distributed in potato-growing regions of Europe. Two types of potato cyst nematodes (PCN) have been detected in the United States—the pale cyst nematode, first identified in Idaho in 2006, and the golden nematode, first discovered in New York in 1941.

If PCN were to become established in the United States, they could potentially result in a loss of domestic or foreign markets for U.S. grown potatoes, an industry currently valued at $3.9 billion ($490 million in Idaho and $65.3 million in New York), resulting in significant market access interruptions. Current eradication, control, management and methods development programs for established populations in Idaho and New York cost approximately $14 million (APHIS contributes $9 million; state and research funds make up the remaining $5 million).

Emerald Ash Borer

nobody@flickr.com (USDAgov) — Tue, 10 Aug 2010 03:27:26 -0700

USDAgov posted a photo:

This invasive insect from Asia targets ash trees. First detected in the United States in 2002, the Emerald Ash Borer (EAB) is now found in fourteen states centered on the Great Lakes basin. Approximately 130,000 square miles are considered infested, representing 7 percent of the native range of North American ash species. The total value of the annual harvest of ash timber is estimated at $150 million. Many species of ash are riparian, filling important niches in the ecosystem, and ash has been widely planted in urban landscapes. In FY 2010, APHIS anticipates spending $37.2 million to protect the nation’s remaining ash resource from emerald ash borer.
