Sustainable Integrated Management of Whiteflies as Pests and Vectors of Plant Viruses in Asia

Geographical focus :: Bangladesh, Indonesia, Malaysia, Nepal, Philippines, Sri Lanka, Thailand and Vietnam Start date :: January 1, 1999
Completion date :: December 31, 2001
Project Name :: Sustainable Integrated Management of Whiteflies as Pests and Vectors of Plant Viruses in the Tropics
Project Leader :: Dr. Pamela Anderson
Subproject Name :: Sustainable Integrated Management of Whiteflies as Pests and Vectors of Plant Viruses in Asia
Subproject Description ::

The overall research objective an understanding of the biotype diversity of Bemisia tabaci, the favored host range for each biotype, the geminivirus diversity, the species affected by geminiviruses and the diversity of potential biological control agents. The activities that will enable the overall objective to be achieved are:
  • Identification of Bemisia tabaci biotypes in Asia.
  • Identification of the major host plants for the different biotypes of Bemisia tabaci in Asia.
  • Identification of key natural enemies of Bemisia tabaci in Asia.
  • Determination of plant hosts affected by geminiviruses, identification of geminiviruses in major crops and development of protocols for detecting viruses in plants.
The key questions to be addressed by this study are:
  • What vector species and biotypes are present and in which countries?
  • What are the key hosts for each biotype?
  • What are the key natural enemies?
  • What are the types of whitefly related problems being encountered?
  • What is the extent of crop loss by geminiviruses?
  • What are the viral agents?
  • What are their basic characteristics?
