IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news, and application of IPM techniques and programs. IPM Lauded for Vegetable Weed Management Two experienced Middle Eastern weed scientists note that weed-caused losses are a significant problem for vegetable crop production in the Near East region, and promote an IPM approach as a fundamental means of improved weed management in the future. In "Components of Successful Weed Management with Special Reference to Vegetable Growers in the Near East," B.E. Abu-Irmaileh and A.R. Saghir explain that IPM, "creates a favorable environment for crop plants" through a combination of practices. The authors suggest a combination of methods that can help reduce weed problems in agro-ecosystems while also reducing negative impacts on workers and the environment. These include:

quarantine procedures to prevent entry and spread of exotic weeds; multiple pest-resistant, well-adapted varieties that resist weed competition and allelopathic effects; fertilizers and water management that give the crop a competitive advantage over weeds; early planting, thorough seed-bed tillage, proper seeding densities, and methods that accelerate germination and crop establishment as well as minimize weed growth; optimum crop plant numbers to maximize crop growth, yet provide soil shading early in the growing season; crop rotation and diversification; field sanitation; use of natural enemies for biocontrol; and, judicious use of chemical weed control practices. excerpted from: FAO PLANT PROT. BULL., 42(4), 191-200, 1994. Institute Emphasizes Crop Protection At the end of calendar 1994, The Plant Health Management Div. of The International Institute for Tropical Agriculture (IITA) at Ibadan, NIGERIA, had 36 crop protection projects underway related to seven tropical crops, plus special programs, in cooperation with over 50 institutions. IITA's recently issued 1994 Annual Report, a full color, 64-page publication, lists specific projects and cooperators. It also offers a perspective for the year in which L. Brader, IITA director general, observes that, "With our general mandate for sustainable agriculture, we cannot confine integrated pest management research to mandate crops alone. Pest problems need to be considered in their entirety."

Thus, in addition to IPM for mandated crops, IITA scientists are working on: biorational control of acridid pests; biocontrol of water hyacinth [Eichhornia crassipes (Mart.) Solms]; as well as development of national biological control programs in 25 sub-Saharan nations. In 1994, IITA was designated the convening center to steer the implementation of the global IPM initiative among all CGIAR (multi-donor, international) agricultural research centers. A technical coordinating committee formed and met in The Hague, NETHERLANDS, in early 1995 to develop policy and establish intercenter projects.

Starting in 1995, all research activities in diagnosis and IPM implementation have been consolidated into six projects. Four are crop-based (banana/plantain, cassava, grain legumes, and maize). Biological control is considered a stand-alone project. And the sixth program focuses on attempting to manage the parasitic weed Striga.

Project Set Up to Transfer Techniques "Pest and Pesticide Management Project Ukraine, PPMP" a multi-thrust program sponsored by the U.S. Agency for International Development, aims to "demonstrate and transfer appropriate pest and pesticide management techniques and regulatory approaches currently being followed in the U.S. and other countries," according to a recent announcement. The Office of International Research and Development (OIRD) at Virginia Tech (university) is coordinating PPMP, a cooperative effort involving the IPM Collaborative Research Support Program and a regional office of the U.S. Environmental Protection Agency, as well as other organizations.

The PPMP program is designed to improve farm worker safety, food quality, and environmental health, reaching national and oblast levels. Proposed interventions include: institutional strengthening of national pesticide agencies; creation of a national Crop Protection Association of Ukraine; and, oblast-level pesticide management and training centers.

Training will form a cornerstone of the two-year effort and be conducted at a variety of sites, both in the Ukraine and the U.S. Technical assistance will fulfill a supporting role for oblast level agencies and cover soil testing, on- and off-site monitoring, as well as methods for the transport, storage, and disposal of agricultural chemicals and containers.

IPM Plays Role in Jordanian Program A joint German-Jordanian project has been launched to introduce ecologically and economically acceptable (sustainable) plant protection methods to Jordanian farmers through promotion of IPM technology. The cooperating agencies are the Jordanian National Center for Agricultural Research and Technology Transfer (NCARTT) and the German Association for Technical Cooperation (GTZ). The project emphasizes biocontrol, which is still not widely used in Jordan. In order to adapt various techniques to specific Jordanian conditions, the GTZ team leader, V. Hasse, would like to exchange information with other experts (regarding mass-rearing of beneficial insect species) on topics such as:

Biocontrol of Bemisia tabaci with Eretmocerus mundus: Dr. Hasse notes a very high rate of host feeding in the project's cultures, which makes mass-rearing of E. mundus virtually impossible, and asks for any publications or personnel communications about this phenomenon, and possible ways to overcome it.

Commercial mass-rearing of Diglyphus isaea against Liriomyza spp.: Here, also, any detailed information on successful mass-rearing of D. isaea would be welcome as the project intends to rear this parasitoid locally in order to provide it to Jordanian vegetable farmers.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other information and resources related to IPM. Poll Reveals Extension IPM Program Variations A 1994 poll of IPM coordinators in the Cooperative Extension Service (CES) of the U.S. revealed that, among 45 respondents, there was a nearly even split between those who agreed and those who disagreed that the chief goal of an IPM-CES program should be to reduce pesticide use. There were several other intriguing responses in the survey, conducted by M.E. Gray and reported in AMERICAN ENTOMOLOGIST as, "Status of CES-IPM Programs: Results of a National IPM Coordinators Survey." A clear disciplinary imbalance emerged: nearly 70 percent of the coordinators had an entomology background, while only four out of 45 had a weed science/agronomy background. Dr. Gray points out the contradiction posed by the lack of weed science expertise in terms of the situations attributed to overuse/misuse of herbicides.

Gray concludes that the answer to his original concern, "Have CES-IPM programs delivered on many of the expectations of early supporters two decades ago," is "yes." However, he adds a caveat that unless funding continues and other issues are fully addressed such as stake-holder involvement, momentum can easily be lost.

Site is Right for Mite Fight Development and proposed field release of a genetically modified predator mite in the U.S. state of Florida, while moving IPM a step closer toward future release of enhanced predators and parasitoids with capability for effective pest biocontrol in agriculture, also has prompted an expression of concern among some observers and challenged the national governmental agency with responsibility for oversight. Entomologist M.A. Hoy and colleagues at the Univ. of Florida recently applied to the U.S. Dept. of Agriculture (USDA) for field release of Metaseiulus occidentalis (Acari:Phytoseiidae), a phytoseiid mite and predator of spider mites, that has been modified in that it carries an introduced bacterial gene. The gene is inactive and serves purely as a molecular marker or tag. The marker was inserted as a method for studying population dynamics and, according to Dr. Hoy, so that the transgenic mite could be evaluated in the field by:

monitoring dispersal; monitoring predator-prey interactions; evaluating climatic adaptation; and, determining whether a released population can be contained and, if necessary, eliminated. Hoy points out that M. occidentalis is native to western North America and has never become established in the eastern U.S., even though it has been mass produced commercially and released in Florida the past two decades as a biocontrol agent in certain crops. Thus, should the new strain disperse beyond experimental plots, it would be very unlikely to establish or persist. The Union of Concerned Scientists, through its periodical, THE GENE EXCHANGE, reported the mite application, but also called for a public meeting to assess implications. At least one other environmental group, and a noted anti-biotechnology activist, expressed concerns that approval of the Florida application will pave the way for releases of other genetically engineered arthropods.

The USDA's Biotechnology Permits (BP) unit is providing guidance to applicants both to address the specific issues associated with the release of transgenic arthropods and to facilitate the application and review process. It's World Wide Web home page is partly dedicated to "The Regulation of Transgenic Arthropods." It includes information about the formation and current activities of a Transgenic Arthropod Team, a bibliography associated with the introduction of transgenic arthropods, copies of recent applications, and discussions of regulatory authority, the permitting process, and issues associated with the release into the environment of transgenic arthropods.

IPM Text Being Built on WWW Two entomologists at a U.S. university have begun a project to create an IPM textbook on the World Wide Web that will eventually contain more than 90 chapters written by experts in a variety of disciplines. The goal, notes co-editor E.B. Radcliffe, is "to broaden our coverage to be multidisciplinary and truly international in scope. We like to think that our site will become an important IPM resource." The other co-editor is W. Hutchison.

The project will be co-sponsored by the Consortium for International Crop Protection and the National IPM Network. Professor Radcliffe points out that, "Eleven chapters have already been submitted and we anticipate the arrival of many more over the next few weeks." He said the concept has met with a tremendous response and that plans call for seeking additional funding to hire a scientific editor and provide much needed clerical and Web page design support.

Asian Study Catalogs Old Practices A few crop protection practices that today's extensionist or crop care consultant probably hasn't recommended recently are: pass a rope over a crop to disturb larvae and cause them to fall on the ground, followed by mechanical "plow in;" scatter boiled rice grains mixed with buttermilk to attract birds which in turn prey on insects; burn trash in fields at night to attract flying insects which then become trapped in the fire; or, sprinkle cow urine on chili plants and other vegetables at the flowering stage. These, and numerous other traditional crop protection methods, were and are practiced in areas of India, according to a fascinating article by M.V. Reddy, a senior plant pathologist at the International Crops Research Institute for the Semi-arid Tropics (ICRISAT). Dr. Reddy and colleagues visited numerous remote farming villages in Andhra Pradesh to catalog long-used, low technology efforts at crop protection. He found that cropping system diversification is slowing yielding to monocropping and that breaks in the cropping cycle are declining. Also cited for pest buildup was reduced use of farmyard manure and increased reliance on improved crop varieties (requiring higher input levels).

In "Survey, Study, and Documentation of Traditional Methods of Plant Protection in the Semi-arid Tropics of Andhra Pradesh, India," Reddy presents descriptions of over 50 traditional methods of crop protection. Most are no longer practiced, but with the information collected, there may be situations when problems related to use of `advanced' methods suggest a reintroduction of the older techniques. Get that cow urine ready!

IPMporium ..... Two U.S. governmental departments Agriculture and Energy recently signed a 5-year agreement to share scientific resources and collaboratively seek ways to reduce national agriculture's reliance on fossil fuels and usage of pesticides. ..... As a follow-up to the article "IPM Certification Program Expands," in IPMnet NEWS #25, January 1996, see also "Integrated Pest Management Certification: A Sign by the Road," C.S. Hollingsworth, AMER. ENTOMOL., 40(2), 74-75, Summer 1994.

..... In 1989 a corporate ranching company in the U.S. imported a few dromedary (one hump) camels from Australia to see if they would help control nuisance brush. It worked so well the company now has 40 camels on seven ranches effectively controlling woody weeds and brush and helping to significantly reduce herbicide application.

..... The California Agricultural Production Consultants Association now officially supports IPM as "a scientific and practical approach to the long-term systems management of pests of plants and animals," according to the group's recent brochure.

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

III. RESEARCH REVIEW research and findings related to IPM. Pheromone Usage Evaluated for Codling Moth Recently summarized research data support the hypothesis that the emission rate of a pheromone required to disrupt sexual communication of the codling moth [Cydia pomonella (Linnaeus)] in an orchard environment is determined by both the insect's population density within the targeted orchard and the pheromone's concentration. Reporting in a recent issue of ENVIRONMENTAL ENTOMOLOGY, U.S. Dept. of Agriculture scientist A.L. Knight suggests that efficacy of any pheromone distribution system should be "evaluated under the range of moth population densities that may occur across its geographical distribution."

In his paper, "Evaluating Pheromone Emission Rate and Blend in Disrupting Sexual Communication of Coding Moth (Lepidoptera: Tortricidae)," Dr. Knight notes that seasonal catches in pheromone-baited traps may exceed 500 moths in some regions while similar traps in a different area may catch only 10-100 moths per season. Under those conditions, using mating disruption as a control technique would be more difficult in the former situation than the latter.

Knight also calls for further efforts to establish economic thresholds perhaps based on moth catches in pheromone-baited trapsforC. pomonellain orchards using mating disruption so that supplementary controls can be applied if the population density is too high early in the season.
