In addition to presentations and discussions of IPM CRSP results, the participants of the symposium also had the opportunity to discuss and contribute to the development of the Phase II Renewal Proposal of the IPM CRSP. Representatives from all four IPM CRSP regions (Africa, Asia, Caribbean, and Latin America), as well as the partner U. S. Institutions, attended the symposium. Since the primary focus of the symposium was presentation and discussion of major results achieved by the CRSP in the three and a half years of its existence, host country representatives and their U. S. based partners reported on their major findings and achievements. Reports were received and discussed from all four regions. The results and achievements covered all the major IPM areas of the CRSP' s involvement: insects, diseases, weeds, socio-economics, policy, and information exchange. Details of the presentations are documented in . these proceedings which should serve as a good source of information and useful reference. We hope the reports in these proceedings will give the reader a representative sample of the much broader range of IPM CRSP activities globally. rn terms of the symposium implementation, the local organizing committee led by the IPM CRSP Latin America site chair did an outstanding job in making all the logistic local arrangements to make the symposium a success. The contributions of Jean-Pierre Amirault and Amy Ostroth in the final formatting and editing of the proceedings for publication are gratefully acknowledged. Brhane Gebrekidan, Program Director IPM CRSP/OIRDNirginia Tech I Sullivan: Purpose of IPM CRSP Symposium and TC Meeting The Purpose of the IPM CRSP Symposium and Technical Committee Meeting Glenn H. Sullivan Site Chair, Latin America First, let me welcome all of the Global IPM CRSP representatives to Guatemala, our Prime Site in Latin America. Further, let me introduce the Site Committee from Latin America: Dr. Victor Salguero, outgoing Site Chair (ICTA); Dr. Guillermo Sanchez, incoming Site Chair (U. del Valle); Dr. Linda Asturias, Site Co-Chair (ESTUDIO 1360); Dr. Allan Hruska, Honduras Program Coordinator (ZAMORANO). The purpose of our meetings this week focuses on the overall objectives of the IPM CRSP in fostering interdisciplinary, participatory research. This research is aimed at improving agricultural production in the developing economies of the world through the introduction of performance proven integrated pest management strategies that are economically, environmentally, and socioeconomically sustainable. It is our mission here to share research fmdings and exchange regional site information that provides greater insight into: • IPM strategies that reduce agricultural losses due to insect, disease, and weed pests. • IPM strategies that rely less on the use of hard chemicals and programmed chemical practices, and more on integrated pest management practices that are sensitive to human welfare and the environment • IPM strategies that accomplish these overall objectives in a manner that enhances the socioeconomic welfare of small producers, rural communities, and society as a whole, and is sustainable over the long-term. The underlying premise of IPM CRSP centers on the scientifically proven fact that when current agricultural production technologies are properly integrated and precisely managed, the goals of immediate economic benefit and long-term sustainability are mutually reinforcing. It is within this shared vision for achieving our goals in the IPM CRSP that we set forth with our agenda in this, our second symposium and fourth annual Technical Committee meeting. Welcome to Guatemala! 1 Gebrekidan: Progress and Challenges ofthe IPM CRSP Highlights ofProgress and Challenges of the IPMCRSP Brhane Gebrekidan Program Director, IPM CRSP, Virginia Tech The Integrated Pest Management Collaborative Research Support Program (IPM CRSP) has made significant progress during the year in working towards achieving its overall objectives. The highlights of the progress as well as the future challenges of the CRSP will be outlined below. Workplans The Year 4 workplan of the CRSP has been under full implementation since October 1996. For Year 5, calls for proposals have been made and received. In these meetings, there is a separate Year 5 planning session in which the Technical Committee as well as other interested Co-PI's are expected to participate actively. Progress on Activities of the Primary Sites All four sites are now fully operational; brief comments on leadership changes at each site are given below: Guatemala There have been Site Leadership changes; Dr. Victor Salguero has been named Deputy DG of ICTA, therefore , a host country site coordinator has yet to be identified. Jamaica Dr. Frieda Eivazi completed her services as the Jamaica Site Chair. New Site Chair, Dr. Bill Ravlin of Virginia Tech, was selected by the Site Committee. Mali Mr. Makan Fofana left the IER and resigned as host country coordinator. Dr. Amadon Diarra is the new Administrative Coordinator and Dr. Kadiatou Toure Gamby is the new Technical Coordinator for Mali.

At the Management Entity at Virginia Tech, there have been changes also.
