IPM NEWS / APPLICATIONS international IPM news and programs Biocontrol Agents Survive Pesticides Four years of trials in the U.S. state of Washington's orchard-intensive area revealed that some important biological control agents of aphids can themselves handily survive application of many commonly used insecticides. Aphids are generally regarded as secondary pests in the area, suppressed by a combination of biocontrols and chemical treatments. However, loss of natural enemies can trigger an upsurge in aphid population and the need for shifting integrated management toward chemical controls. Tests involved exposing lady beetles and lacewings to more than 20 insecticides. The species investigated were: Hippodamia convergens Guerin-Meneville (convergent lady beetle); Harmonia axyridis (Pallas) (multicolored Asian lady beetle); Coccinella transversoguttata richardsoni Brown (transverse lady beetle); and two lacewings, Chrysopa nigricornis and Chrsoplera carnea. Investigators T.S. Price and E.H. Beers, reporting in a recent issue of the AREAWIDE IPM UPDATE newsletter, note that a dramatic finding of the research was the lack of toxicity to the lacewing species. "In fact, it was rather difficult to kill the lacewing larvae," they observed. The ladybeetles varied in their susceptibility to the various compounds. These new results are expected to help growers and consultants make critical decisions regarding pesticide application in orchards and to help preserve useful biocontrol agents. FMI: T.

Invading Plants Pose an Expensive Threat to U.S. The results of a study conducted by a high-level, multi-agency U.S. government committee concluded that the invasion and build-up over time of non-native noxious plants now poses a major threat to the nation's landscape, biodiversity, and economy. "The invasion of noxious weeds has created a level of destruction to America's environment and economy that is matched only by the damage caused by floods, earthquakes, wildfire, hurricanes, and mudslides," B. Babbitt, U.S. Secretary of the Interior, said. "This is truly an explosion in slow motion by opportunistic alien species with few if any natural enemies."

The committee's report, to be published soon as the fact book, INVASIVE PLANTS: CHANGING THE LANDSCAPE OF AMERICA, found a staggering increase in weed-caused losses and costs, estimated at US billion in the 1990s, a 300 percent increase over four decades. The march of non-native plants across the U.S. landscape is so pervasive that the unique differences of regional plant communities are blurring, according to the report, which is characterized as a systematic attempt, involving 17 partner agencies, to define the seriousness of the problem. Over the past decade, the report notes, devastating impacts from invasive species have been reported on every continent except Antarctica. In the U.S., introduced invasive plants comprise from 8 to 47 percent of the total flora of most states, a figure especially alarming considering a recent report from the International Union for the Conservation of Nature documenting that one in eight plant species is globally threatened with extinction. Invasive plants are those that have been introduced into an environment in which they did not evolve. As such, the invaders usually have no natural enemies to keep them in check, thus allowing them to flourish and spread. Aggressive non-native species often have a serious impact on native species; about two-thirds of all endangered species are threatened by non-native species, and as native plant species decline, fauna dependent on them for food and habitat also may be jeopardized. The report's authors blame the increase and spread of invasive plants on increasing human population leading to greater disturbance of the land, increased demand for food and fiber, overuse of public land for recreation and commercial purposes, increased international travel, and globalization of world trade. The problem is compounded, the report adds, because "many introduced plants appear innocuous when first introduced; these plants then adapt, and, in the absence of their co-evolved predators, explode in their new environment." The report calls the threat of invasive weeds "biological pollution" and "a silent green invasion." The head of a cooperating agency explained that, on a plant-by-plant scale, the effects of these plant invaders are often subtle. "It's like metastatic cancer," he said. "It starts with a single individual or seed and then is carried to other places by people or nature where nodes get established and proliferate, eventually affecting entire ecosystems." The report (and publication) were developed by many of the federal agencies (and others) with weed management responsibilities in the U.S. as part of the Federal Interagency Committee for the Management of Noxious and Exotic Weeds. In 1994, in response to the economic and biological threats posed by invasive plants, these agencies began collaborating to develop biologically sound techniques for managing invasive plants on both federal and private lands. After noting the lack of adequate surveys and reliable monitoring data for many of these invaders, the interagency committee cooperated with more than 100 outside authorities to publish a national strategy on the management of invasive plants. "This fact book will help readers understand the scope and magnitude of the problem," Babbitt observed. "We hope it will encourage them to act, to help us control the invaders that are already here and prevent future invasions. People are carrying plants or their seeds from the far reaches

of the globe into every corner of our nation to compete with often to destroy the wonderful variety that nature once gave us." based on information from the U.S. Dept. of the Interior.

IPM MEDLEY general information, publications of interest, and other resources for IPM information Poppy Chopping A scientist has identified a fungus that attacks and destroys the opium poppy (Papaver somniferum L.). According to reports, work conducted at the Institute of Genetics, Plants, and Experimental Botany (Union of Soviet Socialist Republics) at Tashkent, UZBEKISTAN, found a microscopic fungus, Pleospora papaveracea, invading P. somniferum samples. The fungus was isolated and then tested on 42 other local crop species, but was found to be specific to poppy plants. The head of the laboratory at the United Nations Drug Control Program (UNDCP) was informed and subsequently has arranged for a 3-year program to review all the previous experimental work, verify the results obtained, and determine how geographically widespread the fungus is. Protecting Trees Against Disease The three elements that need to occur simultaneously for disease to invade a crop are: ideal conditions, disease organism, and a susceptible host. Since growers usually have little control over weather or the presence of disease spores, strengthening the host (in the case of orchard trees) to better withstand invasion becomes a practical precautionary defense against disease establishment. Plant pathologist M.B. Aichele offered several suggestions for protecting trees against disease: Maintain orchard sanitation by removing (burning) dead and infected trees or brush. Promote vigorous tree growth and balanced nutrition. Avoid pruning in late spring or early summer, particularly on trunks and framework branches. When pruning: if possible, make cuts so water will not accumulate on the cut surface; try to prune when branches are small diameter; on branch cuts, use flexible sealants to provide fungi- cidal protection; Strive to minimize wounds to trunks and scaffold branches. excerpted from: WHAT'S GROWING ON?, 10(1), Spring 1998. Fostering IPM in Africa Among its many programs, 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 has established Africa IPM Link to "foster the initiation and implementation of a network of IPM practitioners in sub-Saharan Africa by facilitating their access to the latest electronic commication and information exchange tools. Participants at an international workshop held in Ethiopia during October 1996 concurred with this approach. One of the program's outputs has been to design and develop an informative website at: as well as a parallel web page, "IPM Resources in French." The Africa IPM Link website also offers useful links to other sites and an array of African and international IPM information. In March 1998, the IPM-CRSP and Africa IPM Link were active participants in the Integrated

Pest Management Communications and Information Workshop for Eastern and Southern Africa convened near Nairobi, KENYA, that involved more than 80 international scientists and IPM specialists. The Africa IPM Link website contains pages devoted to the event. (See related information just below. Ed). FMI: B.

A USEFUL NEW IPM INFORMATION RESOURCE The important topic of IPM has been discussed, reviewed, and debated in thousands of printed pages aimed at target audiences ranging from academics to small growers, with writing styles varying from dense to over-simplified. Yet, a niche remained: to address IPM in a practical, coherent, comprehensive, and down-to-earth manner. A newly published volume, the 1998 IPM ALMANAC, may just fill that niche for many readers. Managing editor T.A. Green, albeit for commercial purposes and to promote his publisher's wide range of mail-order equipment and materials, has pulled together a definitive resource for IPM with extensive reader-friendly `how-to' information, plus useful forms and checklists, and a concise summary of crop-specific IPM practices. A directory lists more than 1,000 "IPM experts" and another list provides URLs for dozens of IPM websites. Dr. Green's introductory comments set the tone for the work: "IPM has come a long way over the last 30 years .. yet we still have a long way to go. Survey results show that only a fraction of those who could benefit are fully implementing IPM." The text of this first edition is U.S. oriented, though Green intends to make future issues more international. There is that liberal sprinkling of promotional information for equipment; and the 175-page volume was published on a newsprint grade paper to keep production costs low. Aside from these possible quibbles, the Almanac delivers universally useful information, well written, in an attractive format, and at a bargain price. FMI: T.A.
