IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs Scientists Criticize Latest Bt-Monarch Study A second recently published study of Bt transgenic corn pollen's effect on the monarch butterfly (Danaus plexippus) has run into a withering barrage of criticism ranging from assertions of scientifically flawed procedures and unsupported conclusions to being labeled "junk science." The research under fire, "Field Deposition of Bt Transgenic Corn Pollen: Lethal Effects on the Monarch Butterfly," (published on line in OECOLOGIA) was conducted by a Midwestern U.S. university scientist and a graduate student and billed as "the first evidence" that Bacillus thuringiensis (Bt) corn (maize) pollen naturally deposited on common milkweed (Asclepias syriaca) caused significant mortality of monarch larvae. The study also predicted, but did not substantiate, that the impact on D. plexippus larvae may be observed "at least 10 m" (33 ft) from transgenic corn field borders.

Biostatistician S.J. Milloy, writing in his column "Junk Science," said the new study "is as much a 'field study' and as realistic as 'Survivor,'" the much-watched, but highly contrived TV program recently run in the U.S. How many butterfly larvae, Mr. Milloy wonders, "will survive when plucked from their natural environment and forced to live on a toxic island," and given no choice in a laboratory setting but to eat milkweed leaves dusted with Bt corn pollen?

Professor and chair of the Dept. of Environmental Biology at the Univ. of Guelph (Canada), M.K. Sears, notes that the work was only partially conducted in the field (leaf gathering); the leaf feeding portion was carried out under controlled laboratory conditions, thus obviating all the environmental factors that can affect pollen deposition on milkweed leaves.

Commenting in CROP PEST ONTARIO, 5(15), 25 August 2000, Prof. Sears points out that, since only a single type of Bt corn was involved, the authors' conclusions "go far beyond the extent of the data presented." Because of the manner in which the research was performed, Sears believes that "the results of these experiments cannot possibly represent the potential impact of Bt pollen from all events, as the authors suggest, across the extensive range of the monarch butterfly in North America."

Univ. of Illinois (U.S.) extension entomologist K.L. Steffey was "dismayed by some of the sweeping conclusions the authors of the OECOLOGIA article made in reference to the potential effects of Bt corn pollen on monarch butterflies in the real world." In a recent issue of the PEST MANAGEMENT & CROP DEVELOPMENT BULLETIN, Prof. Steffey wrote that he doesn't dispute the assertion that potential limitations of Bt corn and other transgenic crops need to be studied, but, he warned, "let's be very careful about interpretations of scientific studies."

Another noted authority, Cornell Univ. entomologist A.M. Shelton, expressed concern over an earlier laboratory-based study reporting Bt corn pollen impacts on D. plexippus that was published. Prof. Shelton felt the results needed to be confirmed under actual field conditions before being rushed into print for what may have been peripheral reasons. The same questions now have surfaced for the latest research which was picked up and reported in an oversimplified and potentially misleading fashion on U.S. national TV.

Group: Eliminate Pesticides and Genetic Modification At a May 2000 international gathering in Dakar, SENEGAL, some 120 attending activists said to represent 40 countries and a disparate array of organizations and causes went on record as committing themselves to no less than a "fight for the elimination of pesticides." The Fifth International Pesticide Action Network Conference created and adopted the "Dakar Declaration" that, beside elimination of pesticides, also calls for terminating all "genetic engineering of organisms in food and agriculture."

The ambitious manifesto spells out a 4-step action plan to achieve the group's dual (and somewhat contrary) goals through developing networks, launching campaigns, educating various publics, and ultimately influencing global policies and practices. |> Pesticide Action Network Africa, Panafric@telecomplus.sn.

QUOTE OF INTEREST "One of the ironies of the current conflict between the proponents and opponents of GMOs is that the technology is inherently green. I cannot help but think that if the technology had been advocated by any sector except the multinational chemical companies with an eye on the world market, the technology would have been embraced by environmentalist groups the same way that windmills and solar cells are."

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general matters, publications of interest, and other resources for IPM information Pathologist Shares Experiences, Offers Photos Based on his long and productive career, a noted international plant pathologist has established a resource-rich web site with a wealth of information about traditional methods of crop disease management practices, traditional agriculture in general, a database of over 3,000 references on traditional agriculture and plant pathology, and free access to, and use of, more than 2,500 pictures on all the above topics. The website and various sub-directories is located at: www.tropag-fieldtrip.cornell.edu/Thurston_TA/default.html. Though retired from Cornell Univ. (U.S.), H.D. Thurston, continues to teach and lead periodic field trips delving into traditional agriculture and methods of crop disease management. Dr. Thurston observes that, "Most practices for disease management used by traditional farmers are cultural practices." Some of these practices include: "altering of plant and crop architecture; biological control; burning; adjusting crop density, depth, or time of planting; planting diverse crops; fallowing; flooding; mulching; multiple cropping; planting without tillage; using organic amendments; planting in raised beds; rotation; sanitation; manipulating shade; and tillage."

For centuries farmers developed techniques many now forgotten or abandoned to restrict and manage plant diseases with few, if any, external inputs, notes Thurston. One example: the use of disease-resistant varieties emphasizes the value of traditional cultivars (landraces) selected over millennia. Landraces are usually genetically diverse and are adapted to their environment and endemic pathogens. Although they may not necessarily produce high yields, generally they are both dependable and stable in yielding some harvest under all but the very worst conditions.

There is a great deal of useful and fascinating information on this website's pages, and Dr. Thurston welcomes all to make use of the material and photos, of course giving appropriate attribution and credit to the source. |> H.D. Thurston, HDT1@cornell.edu.

INSECTS' LINKS TO LANDSCAPES A new (2000) publication examines the important complex aspects of INTERCHANGES OF INSECTS BETWEEN AGRICULTURAL AND SURROUNDING LANDSCAPES. Based on the concept that non-crop elements in a landscape can, and often do, exert substantial impact on insect communities such as fitness and survival editor B. Ekbom, et al have assembled 13 chapters by a notable international group of experts to examine and expand the overall topic. Papers in this 239-page monograph range over numerous facets of agroecosystems, but ultimately emphasize IPM, biocontrol, natural enemies, and the importance of maintaining habitat diversification. |> R. Kennedy, Kluwer Academic Publishers, PO Box 989, 3300 AZ Dordrecht, THE NETHERLANDS. Phone: 31-078-639-2266. E-mail: Robert.Kennedy@wkap.nl. Two More New Titles from APS Press An outstanding new offering from the American Phytopathological Society (APS) concentrates its thrust on diagnosing plant diseases caused by parasitic nematodes commonly encountered in agronomy, forestry, and horticulture and uses its 189 pages to present a range of well tested field and laboratory methods. DIAGNOSING PLANT DISEASES CAUSED BY NEMATODES, by M.C. Shurtleff and C.W. Averre III, introduces plant-parasitic nematodes, describes effective collection methods, and provides an extensive section on classifications and descriptions for 31 genera. The 2000, hardcover work includes numerous generous-size illustrations, plus 38 full color photos.

^^^^^^^^^^^^^^^^^^

The latest update of the acclaimed APS plant disease compendia series is the 2000 version of COMPENDIUM OF CITRUS DISEASES, 2nd Edition. Editors L.W. Timmer, et al, have expanded the 1988 version and included several significant diseases such as citrus variegated chlorosis, caused by Xylella fastidiosa, in Brazil; mancha foliar, caused by Alternaria limicola on Mexican lime in Mexico; and citrus chlorotic dwarf in Turkey, all unknown at the time of publishing the first edition. The new version follows the established softcover format for APS compendia, includes more detailed information for diseases mentioned previously, and brightens its 92 pages with over 200 full color illustrations. The total package stands as a modern and complete reference on citrus diseases. |> APS Press, 3340 Pilot Knob Rd., St. Paul, MN 55121-2097, USA. E-mail: APS@scisoc.org. Fax: 1-651-454-0766.

PEST MANAGEMENT AND THE ECOSYSTEM A new 20-page bulletin from the U.S. government sponsored Sustainable Agriculture Research and Education Program (SARE) uses color photos and case studies to promote the concept of "ecological principles to achieve more sustainable pest management." Titled A WHOLE-FARM APPROACH TO MANAGING PESTS, the softcover, 2000 publication presents successful instances, mainly in text, of cover crops crowding out weeds, scouting to establish action thresholds, use of beneficial organism-attracting plants and environments to enhance pest insect biocontrol, and an overall strategy intended to either reduce pesticide application, reserve it as a last resort, or eliminate it altogether. Among other techniques the editors offer to "'Naturalize' Your Farming System," are establishing refugia, devising means to increase stress on pests, and rotating crops to break pest cycles. |> SARE Publications, 322 Symons Hall, Univ. of Maryland, College Park, MD 20742-5565, USA.

Publication & CD Notes A joint FAO/WHO expert consultation convened during 29 May-02 June 2000 considered food safety and nutritional questions regarding food and food ingredients derived from plants genetically modified using recombinant DNA techniques. The resulting report, SAFETY ASPECTS OF GENETICALLY MODIFIED FOODS OF PLANT ORIGIN, is located on the web at: www.fao.org/WAICENT/FAOINFO/ECONOMIC/ESN/gm/gmreport.pdf. The document includes nine recommendations covering a range of topics.

It's bulging with information, bright to view, and a source of near boundless data on global crop protection that bundles efforts of more than 800 specialists. CROP PROTECTION COMPENDIUM, Global Module, 2nd edition, CD from CAB International offers text, literature references, maps, and illustrations for 1,560 pest organisms and natural enemies of worldwide or regional importance, plus data for 180 crops, and covers conditions in 150 countries. At the Compendium's core is a relational database containing names of 10,000 pest and beneficial organisms, crop plants, and countries. There are additional economic and statistical databases, and provisions for links to external systems and databases.

OTHER RESOURCES GYPSY MOTH IN NORTH AMERICA The accidental release of Lymantria dispar (gypsy moth) during 1868 or 1869 has led to establishment of one of the most pernicious insect pests in North America. In the 130 years since L. dispar (which originally evolved, and has existed for thousands of years, in Europe and Asia) was introduced as an attempt "to build a better silk moth," millions of acres of trees have been defoliated annually. A colorful website www.fs.fed.us/ne/morgantown/4557/gmoth/ sponsored by the U.S. Forest Service presents a wealth of information about all aspects of the species, the widespread problems caused, and the programs aimed at managing it. |> S. Liebhold aliebhold@fs.fed.us. (Information also excerpted, with thanks, from the FOREST HEALTH TECHNOLOGY ENTERPRISE TEAM UPDATE, Spring/Summer 2000.) DETAILED SUMMARY OF BT-CORN Based on research conducted in North America, maize genetically-engineered with Bacillus thuringiensis (Bt) "has the potential to significantly increase field corn yield, as well as reduce the environmental impacts of corn production," concludes a newly revised detailed report. The document, BACKGROUNDER: GENETICALLY-ENGINEERED BT-CONTAINING FIELD CORN, was originally issued in July 1999, but revised and reissued in August 2000. Authors J. Bhatia, et al, provide an in-depth summary of Bt-corn including the primary insect pests impacted, along with a comprehensive reference list. The paper, Technical Report No. 11, devotes extended space to the potential for, and avoidance of, resistance development in the targeted pest species; the authors state that, "Continual management and vigilance on the part of producers, regulators, scientists and industry should ensure the future viability of this production management tool."
