July 1997, Issue no. 43 ISSN: 1523-7893 Š Copyright 2005 IPM NEWS --- international IPM news and programs I. IPM NEWS / APPLICATIONS international IPM news and programs IPM Extension in Canada: Under Pressure An assessment of IPM development and implementation in Canada during 1996 highlights an important shift in IPM extension. H. Philip, chairman of Canada's Expert Committee on Integrated Pest Management (ECIPM), observes that "changes are occurring among agencies delivering IPM extension programs that could adversely impact future progress." Writing in a recent issue of PEST MANAGEMENT NEWS, Dr. Philip points out that provincial governments are reducing resources devoted to IPM extension. Several provinces are considering cost recovery schemes for extension services and materials they provide, IPM included. Concurrently, industry matching funds for IPM research are being emphasized. Philip notes that "the reduction in government extension services should afford some opportunities for private firms and individuals to provide consultative services to fill the void."

Eastern Nepali farmers, jointly with researchers, have launched experiments to evaluate both indigenous practices and research-generated technologies for integrated management of late blight in potatoes. .... The Australian Centre for International Agricultural Research reports that research trials conducted in Fiji found that weekly applications of protein bait to a small area of foliage in every tree in a guava orchard reduced fruit fly-caused losses from 45 to 4 percent. .... Data based on information from three U.S. pheromone dispenser makers indicates that 45,000 acres (18,200 ha) of orchard in the western U.S. have been treated for codling moth (Cydia pomonella) mating disruption in 1997, up from 34,000 ac (13,800 ha) in 1996. .... A study found that farmers from three ethno-linguistic groups in the Philippines considered

six weed species, led by Cyperus rotundus and Pomoea triloba, serious threats to sweetpotato (Ipomoea batatas) production. .... Plants with less slippery (waxey) surfaces can enhance biocontrol by increasing efficacy of generalist predators through reducing the time/energy they spend "grooming" and "falling," according to research from the Univ. of Idaho in the U.S. PUBLICATIONS AUTHORS, EDITORS, AND PUBLISHERS IPMnet NEWS wants to mention any publication related to, or focused on, IPM. To assure coverage, please send a review copy of the publication, with background information where to obtain copies, data about the author/editor(s), costs, and any other particulars or descriptive materials to: IPMnet NEWS, c/o Integrated Plant Protection Center 2040 Cordley Hall, Oregon State University Corvallis, OR 97331-2915, USA After review, materials will be cataloged into the joint CICP/IPPC international IPM and crop protection literature collection (which the worldwide IPM/crop protection community is welcome to use) or returned if so requested.

Managing Arthropod Pests The latest version of ARTHROPOD MANAGEMENT TESTS: 1997, (vol. 22) provides "a timely, useful reference for individuals working with arthropod pests, chemicals, or crop protection," according to the publisher, the Entomological Society of America (ESA). The annual also covers biocontrol agents, and offers a compilation of hundreds of reports, notes ESA.

Kidd, along with five colleagues, have contributed the highly contemporary INSECT NATURAL ENEMIES - PRACTICAL APPROACHES TO THEIR STUDY AND EVALUATION, an important information source supporting more effective biocontrol. Six chapters provide extensive detail relating to behavior, populations, and community and stress approaches and techniques for effectively studying insect biocontrol agents. The 1996 works is hardbound, 491 pages. * International entomologist D.S. Hill presents a broad view of insects and their relationships to humans and human activities in the 1997 title, THE ECONOMIC IMPORTANCE OF INSECTS. It's six chapters and 395 pages cover everything from definitions to descriptions, accompanied by over 200 line drawings and other illustrations. * PARASITIC WASPS provides an up-to-date review of the pertinent biology, as well as ecology and behavior, for an important group of potential pest natural enemies. The hardbound 1997 work by D.L.J. Quicke also offers an entre to relevant literature and a lengthy reference list. The title contains numerous illustrations in its 432 pages.

* A long list of contributors provided the substance that W.O.C. Symondson and J.E. Liddell edited to produce THE ECOLOGY OF AGRICULTURAL PESTS - BIOCHEMICAL APPROACHES. Despite its all encompassing title, this 517-page treatise excludes weed and vertebrate pest species. The 21 chapters cover numerous interesting studies and advanced research. * As mentioned in a previous issue of IPMnet NEWS, two U.S. entomologists, R.G. Van Driesche and T.S. Bellows, Jr., include plant pathogens and weeds in the scope of their 539-page work, BIOLOGICAL CONTROL. The text explores how biocontrol functions and how it can be marshalled to solve pest problems.

Known as Siam Weed, C. odorata is a perennial shrub native of South and Central America that in recent decades migrated to become a serious pest in the humid tropics of Southeast Asia, Africa, and Pacific Islands. The newsletter, sponsored by the Chromolaena Network/Working Group, covers all aspects of the pest's biology and management. C. odorata is considered a promising candidate for biological control through introduction of natural enemies. FMI: R. Muniappan, Agric.
