Chemical Insecticides = Food Security • What is Needed : • Capacity Building for Environmental Monitoring of Chemicals and assessment of Human Health Risks • Better Evaluations of Farming Systems looking at the full range of Economic and non-Economic Indicators
Conservation Biocontrol (1990s) Classical Biocontrol (Late 19th Century) IPM “Rational Use” (1980s) (1960s) • Other Alternatives to Chemicals • Hormone Analogs • Mating Disruption • Insect Diseases • Mechanical Control • Host-plant Resistance Chemical Control (1950s)

Classical Biological Control The practice of importing, and releasing for establishment, natural enemies to control an introduced (exotic) pest, although it is also practiced against native insect pests. Photo Credit: Dr. Paul Jepson, Oregon State University
Conservation Biological Control • Habitat Management to Provide Conditions that Promote Biological Control • Based on: • Understanding Community Food Webs • Manipulating Habitats to create Refuge • Understanding how Landscapes act as “Filters” for large-scale and long-term movement of organisms
Other Alternatives to Chemicals • Hormone Analogs • Mating Disruption • Insect Diseases • Mechanical Control • Host-plant Resistance NP Virus on Spodoptera Exigua on Onions in Indonesia Photo Credit: Dr. Merle Shepard, Clemson University
AGRONOMY • Soil Management • Water Management • Planting Density • Seeds • MARKETING • Cooperatives • Self Financing • “Warrantage” • Farmer Business Schools Community Based Training ( Farmer Field Schools ) IVM Rice – Fish Aquaculture • POST CONFLICT • & HIV-AIDS • Junior Farmer Field Schools IPM : A Natural Entry Point to Community-Based Training IPM = IPPM
International Forums National & Regional Legislative Bodies Local Feeding the Policy Debate • IPPM + • Environmental • Monitoring • Capacity Building • Health Risk Assessment
Farmer Field Schools • More than 50 Countries World-Wide • 7 Countries in West Africa, 55,000 Farmers trained; • Targeting 250,000 in next 4 years • Substantial reductions / elimination of chemical pesticide use • Substantial increases in yields and profits
Good Alternatives Exist ! • At this point we would benefit from : • Understanding and Demonstrating the Real Costs Associated with Chemical Pesticides • Commitment by Governments and Donors to Raising Awareness in the General Population and in large-scale Training of Farmers
