Transgenic Terms and Refugia Requirements

When maize/corn bearing inserted genes from the naturally soil dwelling bacterium Bacillus thuringiensis (Bt) first appeared in 1996, attention focused on the promise of effectively managing key lepidopteran insect crop pests while significantly reducing chemical insecticide application. Eight years later the technology has been embraced in certain regions of the globe, but now with strong emphasis on the needs for insect resistance management, triggering confusion over terminology and procedure.

Entomologist K.L. Steffey, writing in a recent issue of "The Bulletin," an IPM-oriented, frequent newsletter from the Univ. of Illinois, observes that the concept what used to be simply "Bt corn" or "non-Bt corn" has become more complicated by development and availability of at least four types of transgenic corn hybrids, each expressing one, or a combination, of mostly but not all Bt derived proteins.

Originally "non-Bt corn" referred to hybrids that simply were nontransgenic. Dr. Steffey points out that now, because of product differences, the terms "Bt corn" and "non-Bt corn" are no longer as clearly descriptive as they were, in turn leading to confusion over which hybrids should or should not be planted in insect resistance management refugia to balance main crop transgenic hybrids.

a Of course, planting a refuge (mandated to be at least 20 percent of the area planted with the main "Bt corn") to an absolutely nontransgenic hybrid corn would meet refugia guidelines. But Steffey offers an example where a refuge can meet requirements by being planted to a "Bt corn" that expresses one protein, while the main crop is "Bt corn" that expresses a different protein. In other words, the refuge always must be planted with a hybrid that either: a) does not express any transgenic protein; or b) expresses a protein that is different from that of the main crop.

Steffey concludes that it is imperative to "understand the concept, principles, and requirements for insect resistance management, and use the Bt corn products accordingly." He believes that complying with the well established requirements for insect resistance management should enable growers to have the option of continue using transgenic Bt corn well into the future. *> K.L.

Australia Targets Aquatic Weeds

With federal funding through its Natural Heritage Trust, Australia recently established a 10-member National Aquatic Weed Management Group and named A. Petroeschevsky as national aquatic weeds management coordinator.

Three aquatic weed species anticipated to be named as national weeds of significance are: Alternanthera philoxeroides (alligator weed); Salvinia spp. (salvinia); and, Cabomba caroliniana (cabomba).

The management group aims to increase awareness and cooperative efforts in integrated management of the three main weed species with a goal of reducing their spread and negative impacts. *> A.

Helping to Thwart Invasive Plants

The City of Nedlands in Western Australia recently received arequest and a cheque, from an individual in another country with a similar environment, for a quantity of native wildflower seed. Nedlands responded, but in an unusually forthright, articulate, and appropriate manner given the global battle to stem the tide of invasive plant species. Here is the response letter's text, composed by Nedlands Bushcare Officer S.D. McCabe, and sent out with the authority, and over the signature, of Nedlands mayor L. Taylor:

"I understand the appreciation you have for our beautiful country and our unique flora, however, I am unwilling to send you the seeds you have requested.

"Our wonderful and diverse bushland is suffering under the strain of introduced species from countries with climates similar to our own. Many exotic plants have escaped from gardens and invaded bushland areas. These plants are a damaging curse that is very difficult to lift, as they become weeds that smother local wildflowers and severely damage the habitat of our precious wildlife. Weeds are a very serious and an extremely expensive issue not just here in Nedlands but right across Australia.

"I am aware that many Australian plants become weeds when planted beyond their natural borders and I cannot, in all conscience, risk contributing to anything that might compromise the health of the [country's] environment. As such, I am enclosing a cheque equivalent to the 20 Euro which was sent to us."

Yours sincerely, L. Taylor, Mayor, City of Nedlands, WA

TWO VIEWS OF BIOCONTROL No less than 62 international authorities are represented in a 2003 work, BIOLOGICAL CONTROL IN IPM SYSTEMS IN AFRICA, produced to support the thesis that "biocontrol components provide a common basis for many integrated pest management (IPM) systems," though their importance varies depending on the particular system. The hardbound volume's 24 chapters present an authoritative view of crop protection, and significant attendant problems, in Africa. Editors P. Neuenschwander, et al, document the contributions of bio-IPM to African agriculture, but realistically also cite the hurdles and instances of failure. Arthropod management receives major attention, though weed management and pathogen management are included. A 16-page compilation of 64 color photos enhances the text which focuses on case studies and promising research outcomes. The 447-page book focuses on sub-Saharan Africa and covers biocontrol by naturally occurring and exotic agents, as well as (local) environmental manipulation.

Keynote presentations at the International Organization for Biological Control's 2002 international symposium, addressing recent developments in genetics and evolutionary biology and their relevance to biocontrol, form the basis for GENETICS, EVOLUTION AND BIOLOGICAL CONTROL, a late 2003 publication. Twelve chapters delve into several themes including: pest and natural enemy genetic structure; molecular diagnostic tools in biocontrol; pest and natural enemy origins; and predicting pest and natural enemy evolutionary change. An international contingent of scientists provided the 288-page monograph's text as organized by editors L.E. Ehler, et al. The hardbound work probes new issues for the major approaches in applied biocontrol such as use of molecular genetics, mass rearing of transgenic agents for augmentative programs, and compatibility of transgenic crops and natural enemies in conservation biocontrol.

NEW, EXPANDED LANDSCAPE IPM MANUAL The Univ. of California's Statewide IPM Program has produced yet another superb addition to its extensive collection of IPM manuals. The 326-page, 1994 edition of PESTS OF LANDSCAPE TREES AND SHRUBS, AN INTEGRATED PEST MANAGEMENT GUIDE provided highly useful text and visuals that have now, 10 years later, been expanded into the 501-page second edition containing 70 new sections for diseases, weeds, and insects/mites. The reader-friendly tree-and-shrub pest tables have been doubled to over 100, providing clear guidance for identifying and effectively managing common pest problems. The 2004, softbound work features more than 430 full color photos, plus 117 drawings, in addition to references and a glossary. High quality printing on coated, low-reflection paper stock enhances readability. The overall end result is a well organized, comprehensive, graphically appealing resource that is clearly a key IPM publication. *> ANR, Univ. of California, 701 San Pablo Ave., 2nd. floor, Oakland, CA 94608-1239, USA.

RESEARCH TARGET: RODENTS Rodents have emerged as a significant agricultural pest throughout Southeast Asia during the past decade. A recent publication from the Australian Centre of International Agriculture (ACIAR) sets forth practical instructions for field methods associated with population studies of rodents and logically is entitled FIELD METHODS FOR RODENT STUDIES IN ASIA AND THE INDO-PACIFIC. The attractively presented 2003publication includes experimental design, trapping methods, safe handling of rats and mice, and techniques for assessing reproductive activity and rodent damage to crops. Authors K.P. Alpin, et al also provide a taxonomic key for rodents that are major agricultural pests in SE Asia and the Pacific region as well as other non-pest rodents. The 223-page volume is loaded with clear descriptions and illustrations as aids to identification, plus summaries of current knowledge, geographic distribution, diet, habits, and behavior for individual species. The 3-part book, ACIAR monograph MN100, can be freely downloaded from: www.aciar.gov.au or obtained from ACIAR. *> Communications, ACIAR, GPO Box 1571, Canberra ACT 2691, AUSTRALIA. comms@aciar.gov.au .

INVADERS OF THE ENVIRONMENT In addition to well recognized environmental villains, there is another, equally serious global threat: the accidental or intentional movement of living organisms from originating locales to environments wherein a lack of natural enemies can lead to population explosions that rapidly degrade ecoregions. One outcome of a meeting that explored his critically important emerging topic, labeled "biological pollution," is a 2004 softbound publication, BIOLOGICAL POLLUTION: AN EMERGING GLOBAL MENACE, that presents a broad spectrum of concerns to the conservation minded among us. Editor K.O. Britton arranges 10 chapters by a group of experts to introduce the "BP" concept, offer specific horrific examples, and lastly set forth existing defenses as well as proposed improvements. Written in nontechnical language, the 124-page work includes over 20 black/white photos, and concludes with a rousing chapter entitled, "Fighting Back!," encouraging problem recognition, prevention, and elimination through both global and local action. *> APS Press, 3340 Pilot Knob Rd., Saint Paul, MN 55121-2097, USA. aps@scisoc.org .

IPM IN THE STATE OF MICHIGAN The spring 2004 issue (vol. 10, no. 1) of "The IPM Report," from Michigan State Univ. (MSU) incorporates the MSU IPM Program 2003 Annual Report, a recapitulation of the year's activities and accomplishments. The report emphasizes the maze of partnerships and joint efforts generated "to bring better pest management to Michigan." The online document can be found at: www.ipm.msu.edu . An example of the IPM program's collaborative work is reflected in a new website grapes.msu.edu designed as a single information source for the state's juice and wine grape growers and featuring heavy emphasis on IPM within an integrated vineyard management framework. The attractive site offers numerous links such as those for identifying common diseases, insect and mite pests, nematodes, and beneficial organisms (but sadly nothing readily apparent on weed management). *> J.N.

U.S. REGIONAL IPM CENTERS AND THE IPM-CRSP --- news, developments

Vegetable Production IPM for U.S. Midwest

A lively and informative website hosted by the Univ. of Minnesota serves as a vegetable production IPM resource for the Midwestern U.S. by providing free timely information about all aspects of vegetable crop IPM emphasizing pest insect management and related matters of interest to the region.

The site, better known as "VegEdge," www.vegedge.umn.edu pest (insect, weed, disease) fact sheets, research updates, historical data for pest insect infestations, and a wide wedge of additional information to assist growers, processors, and crop consultants in making daily IPM decisions.

The opening page presents an interactive map showing 24 hyperlinks to newsletters and other information sources in 12 U.S. states and Ontario Province in Canada. Clicking on any of the sites promptly brings up a regional, linked site, many of which have additional links, thus vastly broadening the scope of available information.

VegEdge doesn't hedge its bets and so includes a link to the free, electronic Radcliffe's IPM World Textbook (ipmworld.umn.edu a 66-chapter compilation of IPM topics technical, historic, and scientific. The site (also available in a Spanish language version) was conceived to provide an electronic alternative or complement to printed texts. Thematically, the site aims for "state of the art information from the world's leading experts on all aspects of IPM."

Taking the pledge to maintain VegEdge are W.D. Hutchison and S.W. Burkness Dept. of Entomology, Univ. of Minnesota, who, in collaboration with colleagues in other states, strive to dredge up and make available a sledge load of useful IPM information.
