IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs Insect Science Powers International Center With its insect science-based activities realigned and streamlined to better address the constraints to development influenced by arthropods, the International Centre of Insect Physiology and Ecology (ICIPE) in Kenya has positioned itself to generate, refine, and deliver important technologies for global agriculture in the next two decades. ICIPE was originally conceived in the late 1960's as a "center of excellence" for research into insect physiology and endocrinology serving mid-Africa. Expansion and the replacement of "endocrinology" with "ecology" marked the Center's progress along with continuation of a research philosophy that recognized the needs of resource-poor rural communities in the world's tropical regions. Further rapid growth and shifting technologies lead to a mid-90's metamorphosis that produced the current organizational structure: a trio of "mega-projects" aimed at agriculture, human health, and the environment and an expanding network of international linkages.

Under the philosophy that "Farming practices, pest management included, that endanger ecosystems are no longer acceptable," IPM plays a conspicuous role at ICIPE, cutting across programs and four disciplinary departments. As one example, ICIPE continues to research and develop IPM strategies for banana pests (weevils and nematodes). Cross-program efforts involve behavioral ecology, semiochemicals, and biopesticides. Center staffers, in collaboration with other national and international groups, are actively investigating eco-friendly pest management methods for indigenous vegetable crops, primarily in Africa.

In another effort, extension of earlier trials using interplantings of the forage legume Desmodium uncinatum to reduce stemborer populations in maize (by attracting a higher population of natural enemies) has been found to also suppress infestations of the devastating parasitic weed, Striga hermonthica. ICIPE scientists have identified several other plants, such as Napier grass/Elephant grass (Pennisetum purpureum) and Sudan grass (Sorghum sudanense), with properties that help reduce stemborer intensity.

In its new configuration, the Centre collaborates and works in partnership with numerous other international centers, laboratories, agencies, universities, and both governmental and non-governmental organizations. Earlier in 1998 ICIPE hosted the Integrated Pest Management Communications and Information Workshop for Eastern and Southern Africa that involved more than 80 international scientists and which was sponsored by a broad coalition of national and international entities. (The Workshop was discussed in IPMnet NEWS nos. 52 and 53. For extensive details, check the website: ipm-www.ento.vt.edu:8000/ail/ipmcw/intro.html.)

ICIPE's 1996/97 ANNUAL REPORT offers a concise summary of its current activities (which are far broader than indicated in this brief summary), achievements, and blueprints for the future, all set forth in a graphically attractive format.

Decrease Disease, Gain Healthier Roots Extensive healthy roots, in contrast to disease-infected roots, obviously improve a plant's ability to absorb moisture and nutrients from the soil. To obtain and maintain a high degree of root health, five principles have been proposed: Reduce, even if only modestly, the power of soilborne pathogens to cause disease. Start a crop from pathogen-free material; avoid cultivating fields known to infested with disease, or use methods (solarization, flooding) to eliminate disease organisms.

Carefully manage the microenvironment of the soil where pathogens are active to significantly reduce the severity of root diseases. Follow practices that improve soil drainage; adjust temperature, moisture, and pH to discourage pathogens and favor their natural enemies.

Introduce or foster naturally occurring biocontrol agents in the soil that surrounds roots, either through cultural practices or by incorporation with planting material.

Target specific pathogens with narrow-spectrum fungicides applied with planting material or directly to the soil. When needed, apply materials singly, or as mixtures, making sure that the material is taken up by roots or contacts the pathogen.

Genetically increase the trait already present in plants to tolerate or resist virtually any biological or environmental stress factor, including soilborne pathogens. A long-term approach. excerpted from: "Biologically Controlling Soilborne Pests: A Research Overview", METH. BROM. ALTERN., 3(1), January 1997.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other resources for IPM information Weed Science in Italy The Societa Italiana per la Ricerca sulla Flora Infestante (SIRFI), or Italian Weed Research Society, now has approximately 150 members, has published a weed identification handbook, issues a twice-yearly newsletter, and organizes periodic symposia. The group, formed in 1975 (under a different title), aims to promote progress in weed science, to collect and disseminate information and results, and to assist with relevant communication. It convenes biennial conferences on various weed science topics and publishes the proceedings.

Correction The article "Fostering IPM in Africa," included in IPMnet NEWS #53, May 1998, stated an incorrect website for Africa IPM Link, the innovative effort from the IPM Collaborative Research Program (IPM-CRSP) managed by the Office of International Research and Development at Virginia Polytechnic Institute and State University (VT) and funded by the U.S. Agency for International Development. The correct website (with a hyphen, not an underbar) is: ipm-www.ento.vt.edu:8000/ail/index.html The NEWS regrets the error. IPMporium .... Results of field trials revealed that denatonium benzoate, a bitter compound, was not effective in repelling pocket gophers (Thomomys talpoides Rich.) nor reducing their damage to conifer seedlings. .... A California study confirmed that bats feed on crop pest insects such as moths, midges, and beetles, as well as flies and mosquitoes.

.... In Cambodia a scientist observed that, whereas nationally, grasshoppers probably do not contribute much to annual crop loss, an individual field can be devastated, and an entire seed bed can be destroyed by grasshoppers in a single day.

.... A "Christmas" tree farm in Denmark, where certain herbicides are now bannedfound that ostriches reduce weeds and unwanted plants without damaging young trees.

.... A representative of a major U.S.-based farming cooperative cites a low birth rate in the mid- to late-1980s and the "farm crisis" as reasons the organization has well over 40 commercial chemical applicator positions in the mid-western U.S. going begging.

METHODS FOR CONTROLLING VECTORS An impressive, information-laden new publication from the World Health Organization (WHO) more than lives up to its label as the "the first comprehensive guide to simple and affordable methods of vector control." The beautifully produced, 412-page volume, VECTOR CONTROL: METHODS FOR USE BY INDIVIDUALS AND COMMUNITIES, was prepared by J.A. Rozendaal, and offers both technical background and, more importantly, practical, usable techniques for controlling some of the world's nastiest disease vectors. Copious line drawings supplement the clear text. Important sections address proper, safe usage of pesticides. Each of the 10 chapters, covering mosquitos and other biting Diptera, tsetse flies, and many other widespread vector species, cites references and provides lists for further reading.

IPM RESEARCH/TECHNICAL PAPERS --- categories and topics related to IPM

III. RESEARCH/TECHNICAL PAPERS research/technical topics related to IPM. FEATURED PAPER A newly emerging method for artificial augmentation, itself a traditional technique for introducing natural enemies in biocontrol programs, was the basis for the paper, "Novel Application of Gels as Potential Carriers for Beneficial Insects," by D.J. Jenkins et al. Research focused on a potential carrier media for the eggs of Perillus bioculatus (F.) and Podisus maculiventris (Say), two predators of Colorado potato beetle (Leptinotarsa decemlineata [Say]), a serious pest insect. While the paper reports that gels caused some decline in egg hatch rates, the authors believe that using gels to deliver eggs of predator species may have a practical application for integrated pest management in the future.
