IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news, and application of IPM techniques and programs. Virus Approved for Codling Moth Control The periodical CALIFORNIA AGRICULTURE reports that, after 14 years of testing, a Univ. of California entomologist, L.A. Falcon, has received federal (U.S.) registration for use of a granulosis virus to control codling moth (Cydia pomonella L.) on apple, pear, walnut, and plum trees. Field tests have demonstrated that, with proper application of the virus a naturally occurring baculovirus moth larvae are controlled as effectively as with commonly used pesticides. The baculovirus has the advantage of attacking a narrow range of species, thereby avoiding impacts on both beneficial species and avoiding proliferation of secondary pests.

The baculovirus is both more labor intensive to apply and monitor, as well as more expensive, than a pesticide. The intent is to not to replace pesticides entirely, but to supplant and reduce the amount used. Dr. Falcon noted that integrating baculovirus use with judicious application of pesticide could help keep orchard moth populations at very low, economically tolerable levels while preserving ecologically healthier conditions.

Insect's Resistance Threatens Coffee Crop Recently published research reports that, on the South Pacific island of New Caledonia, the coffee berry borer (Hypothenemus hampei) is now 25 to 100 times more resistant to the insecticide endosulfan than are borer strains in other coffee growing areas. While New Caledonia is remote from most other coffee growing areas making direct spread of insecticide-resistant borers less likely, the study's authors warned that the mutation protecting the New Caledonian borer from endosulfan could occur anywhere that this insecticide is used to control the coffee berry borer.

Endosulfan is a neurotoxin that attacks insects through their central nervous system. It is the primary insecticide used against the coffee berry borer because it can penetrate the coffee bean and kill the insect larvae whereas many other insecticides cannot.

U.S. entomologist J.J. Stuart of Purdue Univ., one of the report's authors, notes that resistance to endosulfan develops through a mutation of what is called the GABA gene, a part of the inherited gene pattern that manufactures a protein associated with the nervous system. The unusual reproduction system of H. hampei means that if a generation develops a mutation that confers resistance to endosulfan, the genes could pass unchanged from one generation to the next, quickly spreading throughout an entire coffee region.

"This resistance mutation has arisen once and probably will again," Stuart added. The widespread use of endosulfan increases the possibility of the borer developing a resistance, he said. For more information contact: J.J. Stuart, e-mail: jeff_stuart@entm.purdue.edu. Phone: 1-317-494-4561.

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general information, publications of interest, and other information and resources related to IPM. Crop Protection Gains at ICRISAT The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) headquartered at Hyderabad, INDIA, has reorganized its research thrust into seven research divisions. Research conducted within the Crop Protection Division alone now accounts for approximately 45 percent of all ICRISAT's activities, a senior member of that division reports. As one outgrowth of increased emphasis on crop protection, division staff members, along with other collaborating organizations, are accelerating information dissemination through a variety of pamphlets and periodic newsletters. Among the latter, the IPM AND IRM NEWSLETTER FOR LEGUME CROPS IN ASIA and the PODBORER MANAGEMENT NEWSLETTER focus on a specific crop group and a single insect pest (_Helicoverpa armigera_) respectively. The podborer periodical primarily concerns the topic of insecticide resistance.

For Asian farm systems, two avian species, the "drongo" and the cattle egret, are important predators of insects, particularly defoliating caterpillars. Entomologists, notes the legume crops newsletter, have come to regard the presence of these two birds as, "indicators of `healthy farms' places where IPM is happening."

For information, contact P. Traynor, traynor@nbiap.biochem.vt.edu.

..... The South African government has launched a massive program to clear invasive plants from water catchment areas and gain an estimated 30-50% in water yield annually.

..... Delegates to a 1994 international workshop on pesticide policies, sponsored by FAO on behalf its Panel of Experts on Integrated Pest Control, prepared "A Conceptual Framework for Pesticide Policy Studies," aimed at aiding realistic assessments (economic benefits, external costs, social consequences) of pesticide use and subsidies, and approximation of "socially optimal" levels of pesticide use.

..... The International Mycological Institute continues to add to its series of loose-leaf, detailed "Descriptions of Fungi and Bacteria" sheets. IMI can be contacted at: Bakeham Lane, Egham, Surrey TW20 9TY, U.K.

..... The Western Regional IPM Program (USA) has issued its 񓟫 Management Report," the fourth in a series. Five regional IPM research programs are highlighted.

..... The 1995 World Food Prize was awarded recently to H.R. Herren, a Swiss-born entomologist who organized a biological control program to eradicate the cassava mealybug (Phenacoccus spp) in 30 African countries. Herren identified a tiny wasp, E. lopezi, as the mealybug's natural predator and led an international effort to move the wasp to Africa, breed it in sufficient numbers, distribute it across Africa, and organize the people needed to monitor and operate the program.

Crop Breeding to Reduce Pesticides R.A. Robinson, a Canadian/British plant scientist with more than 40 years of wide-ranging global experience in crop improvement for both commercial and subsistence agriculture, has authored RETURN TO RESISTANCE, a new work subtitled "Breeding Crops to Reduce Pesticide Dependence." The dilemma Robinson sees is a choice between "food and pollution on the one hand, or purity and famine on the other. In fact, there may be a solution to this dilemma," he observes, leading to both adequate food supplies and freedom from excessive crop protection chemicals.

The 500-page, softbound work provides an answer by explaining "how groups of farmers can work together to breed crops with effective, durable resistance to all locally important pests and diseases," according to the book's publisher. Dr. Robinson analyzes crop breeding's successes and shortcomings, and explains new techniques for breeding food crops with inherited immunity, or `horizontal resistance.' The 1996 volume includes numerous tables, a glossary, lists of resource groups and organizations, and a bibliography.

MITE BIOCONTROL VIDEO In Australia, NSW Agriculture has produced a video about the biological control of mites in vineyards using native phytoseiids, primarily Doreen's predatory mite and the Victorian predatory mite. These two species (and others) are expected to help remove miticides from wine production (in Australia) saving the industry millions of dollars. Primarily aimed at grape growers, the video, entitled "Wine, Women and Vineyard Mite Control with Doreen and Victoria," will, according to one source, "also appeal to teachers and the general public. Acarologists can use it as propaganda to demonstrate the economic and social benefits of studying mites." For more information, contact; Publication Sales Unit, NSW Agriculture, Locked Bag 21, Orange, NSW 2800, AUSTRALIA.

TRAINING FOREST PEST COURSE SET The Canadian Forest Service, Canadian Institute of Forestry, and the Ontario Ministry of Natural Resources will jointly conduct a Forest Insect Management Course from 5-9 February 1996, at Sault Ste Marie, Ontario, Canada. The course is designed to advance the skills and knowledge of forestry professionals in current techniques and principles for planning, implementing, and evaluating forest insect management programs, not simply as tactical control programs, but in reference to the broader scope of Integrated Resource Management (IRM). Course instructors will come from all across the North to facilitate a 5-day learning experience through lectures, field trips, practical field exercises, and discussions groups.

Completion of the course will help participants gain improved awareness of forest insect management principles, insect population surveys, damage appraisals and impacts, insect management tactics and strategies, insecticide application technology, as well as current advances and trends in organizing an insect pest management program.

IPM COURSE PROPOSED Interested in IPM for scale and mealybug pests on trees? In 1997 the International Institute of Biological Control (IIBC) is planning to conduct an international IPM training course for crop protection specialists in 1997 at IIBC-Pakistan. As proposed, the two-week practical course would draw on IIBC's experience with these pests in mango, apple, stone fruits, neem, almond, and forestry trees. Participants would learn:

how to identify scale and mealybug pests and their natural enemies; how to rear and release parasitoids and predators; and, how to develop an IPM system integrating natural enemies with cultural and other control methods. Suggestions for this course are welcome. For more information and to express interest, contact: S. Williamson, Training & Information Officer, IIBC, Silwood Park, Ascot, Berks SL5 7TA, UK.

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

III. FORUM / EDITORIAL viewpoints, opinions, and discussion of IPM issues. [ In a thoughtful article published in 1993, a U.S. rural sociologist articulately identified a fundamental root cause of resistance to broader adoption of sustainable agricultural techniques. The same tenets also clearly apply to implementing and adopting IPM. Excerpts from the article follow. Ed. ]

"Most of us find it easy to agree with the basic principles of sustainable agriculture which call for the development of farming systems that are environmentally sound, socially beneficial, and profitable. But it is not so easy to translate a broad set of principles and goals into a set of practical recommendations to improve farming practices, especially when the issues are charged with emotion, controversy, and misunderstanding. What are the roots of the polarization between those who advocate `sustainable agriculture' and those who feel skeptical, and even suspicious of it? "Many in the agriculture community view sustainable agriculture as a personal criticism or an attack on conventional agriculture, of which they are justifiably proud. `I guess that the main thing people get defensive about when you say sustainable,' explained one [interviewed extension] agent, `is that it implies that what they've been doing is not sustainable. And that's the biggest issue.' They [agents] feel that by promoting sustainable agriculture, society is unfairly blaming farmers for pollution, and unfairly targeting agriculture for reform. Farmers are willing to go the extra mile to improve environmental impacts, but consumers ought to share the burden.

"And many are skeptical of the economic feasibility of sustainable agriculture, particularly related to labor and equipment costs. `If you go from chemical pesticides to cultivation, you have to have more labor, and more equipment,' argued an Extension agent. At the same time, [agents] feel that farmers are not given enough credit for what they're already doing to improve environmental impact. `We've been doing it [cover cropping and rotations] in vegetables for years!' complained another. And yet we don't get credit for what we are doing.'

"Unfortunately, the history of conflict, misunderstanding, and ignorance surrounding sustainable agriculture still divides the agriculture community. We need to cultivate a genuine respect for all who are sincerely concerned about the future of agriculture. We need to learn how to work together to address both longterm societal goals of sustainability and the immediate needs of farmers to stay in business."

QUOTES "It was found that weed problems and ways to improve their management are generally not well understood, and that hand-weeding, the major control activity at small farm level, is taken for granted rather than rated as an economic liability in many countries."

Labrada, Weed Control Officer FAO Plant Protection Service [From: "Status Report on Weed Management Needs and Activities in Developing Countries," a 72-country status report designed to identify constraints and progress in weed management activities in developing countries, FAO PLANT PROT.

IV. RESEARCH REVIEW research and findings related to IPM. IPM for Sweet Pepper As part of the project, "Development of an Ecologically-based Integrated Pest Management (IPM) Program for Sweet Pepper," a team of researchers working in Spain investigated and sought to quantify pepper crop yield losses due to various yield-reducing agents (aphids, viruses, nematodes, and weeds) acting jointly and individually. Results suggested that some weed species were able to act as important reservoirs for aphid vectors and enhance virus spread. Floating row covers, when established at the correct time, were found to be an adequate cultural strategy to control pepper viruses. The researchers calculated economic thresholds and maximum risk periods for some of the most damaging pests of pepper. A computer-based information model for pest control was completed as paFor more information, contact: A. Fereres,. e-mail: ebvaf22@PINAR1.csic.es.
