Conference on Extension Delivery of Biological Control Information

The Entomological Society of America (ESA) and the American Phytopathology Society (APS) will be holding their annual meetings together this year, in Las Vegas, November 8-12.

During the afternoon of Sunday, November 8, a half-day joint ESA/APS Informal Conference on Extension delivery of biological control information will be presented. The title of the conference is "The Role of Extension in Implementing Biological Control in IPM Programs: Perspectives from Entomology and Plant Pathology". The objectives of the conference are to compare and contrast the scope of biological control within entomology and plant pathology and to share information on the status of extension programming in the two disciplines. We hope that both extension workers and biological control researchers will attend the conference and share their experiences and perspectives on this subject. The conference is sponsored by the Biological Control Working Group of the Experiment Station Committee on Policy (ESCOP) and is organized by Daniel L. Mahr, Department of Entomology, University of Wisconsin-Madison and Barry J. Jacobsen, Department of Plant Pathology, Montana State University-Bozeman.

Burkholderia cepacia: Friend or Foe?

The bacterium Burkholderia cepacia (formerly Pseudomonas cepacia) was first described as a pathogen of onions. A common soil saprophyte with tremendous genetic diversity and the capacity to utilize a wide range of nutrients, this species is also an important agent for biocontrol of fungal diseases and bio-remediation. Its status as a registered biopesticide and its future as a commercial biocontrol agent is jeopardized by recent research which suggests that some strains can colonize the lungs of cystic fibrosis patients, in some cases leading to rapid decline and death. A symposium on Burkholderia cepacia will be held on Monday, November 9, 1998 at the annual meeting of the American Phytopathological Society (joint this year with the Entomological Society of America) in Las Vegas. Sponsored by the APS Committee on Biological Control, the symposium will bring together experts from phytobacteriology, biological control, medical microbiology, genetics, epidemiology and EPA to discuss the ecology of this fascinating organism and to probe the current state of the art for distinguishing beneficial and potentially harmful strains.
