RDA (Rural Development Administration) of Korea initiated the AFACI (Asian Food and Agriculture and Cooperative Initiative) a multilateral cooperation to share and transfer agricultural technologies to improve food production, sustainable agriculture and address the MDGs. AFACI was inaugurated in 2009 in Seoul and the first General Assembly was held in 2010 in the Philippines. One of the AFACI projects is to establish a collaborative network to address the rice planthopper problems. The international workshop was held in Suwon, Korea 26 – 28 April, 2011, to development phase I workplans.
Rice planthoppers are migratory pests and reliance on micro level tools, such as host plant resistance and insecticides, are inadequate to manage such a macro problem. The network, supported by RDA, aims to establish a framework for international cooperation to assess the planthopper problems in Asia, collect pest migration data, develop migratory models and characterize the viruses they transmit. It will focus on developing and exchanging macro level tools and paradigms for managing the pest problems in wide geographic area, social and political dimensions. Representatives from China, Cambodia, Indonesia, Japan, Korea, Laos, Malaysia, Myanmar, Philippines, Thailand and Vietnam shared country experiences and developed joint research plans.
In his keynote address, Dr Dale Bottrell, retired Maryland University professor, called the recurring threat by BPH in Asia “Resurrecting the Ghost of the Green Revolutions Past”. In the International Brown Planthopper Conference organized by IRRI in 1977, scientists concluded then that insecticides were the most persistent factor triggering BPH outbreaks. And again in the 2008 Planthopper Conference, scientists concluded that pesticide use had recently increased triggering outbreaks in several intensive production areas. He urged the network to adopt a broader landscape perspective in developing new management strategies.
Rice Planthopper Project’s outputs and experiences were shared with participants and to facilitate out scaling, especially to other countries in the region, further linkages with the Network were established. These include joint workshops, common research sites, data and information sharing and capacity building.
The RDA has developed the Asian Migratory Insects and Viruses Surveillance (AMIVS) to to serve as a platform for monitoring pest movements in the region. Users can share country information as well as have access to data from participating countries. Japan also maintains a pest migration data base and prediction system and wind trajectory maps may be downloaded from http://agri.narc.affrc.go.jp/
