  1. Fruit/Melon Fly Mapping in Mekong Region S. Jothiganesh GIS Specialist, RIMES, Bangkok.

  2. Introduction The fruit fly infestation has been a major problem for the crops that have been grown along the Mekong Region. GIS helps to identify vulnerable areas, pattern of infestation and the damages caused due to the Oriental fruit fly and Melon fly at various geographic scales .

  3. GIS for IPM • Effective tool in monitoring, predicting, managing and fighting the spread of crop diseases and pests. • Identify the spatial extent and spatial patterns of the infestation. • Forecasting spatial spread of diseases through risk assessment models which will be of help for pest control activities • Infestation data can be combined with environment and socio-economic data as an effort to create a decision support model. This allows the identification of vulnerable areas that need to be targeted first for pest control activities

  4. Objectives • Prepare GIS maps for Mekong countries showing infestation on crops, damage, area, seasonality, IPM practices etc. • Regional identification and ranking of the risk factors using GIS for selecting vulnerable areas (Provinces). • Provide information on the extent of problems in identified areas, types of crops and fruit-fly species present.

  5. Study Area • Fruit Fly Mapping Countries • Cambodia • LaoPDR • Thailand • Vietnam • Level of Mapping • Province Level

  6. Spatial Analysis • Spatial Analysis allows users to study the relationship between location and its characteristic geographic feature • Analysis allows user to study the variations of a parameter or phenomenon of a object over a location or geographic region.

  7. Multi Criteria Analysis (MCA) Multi Criteria Analysis in GIS is a method of weighting or scoring criteria to assess their importance to support Decision Makers • Criteria • Fruit growing area • Fruit fly infestation • IPM Status

  8. Fruit/Melon Fly Regional Mapping

  9. Total Fruit growing areas in Laos

  10. Fruit fly Present /Absent

  11. NIPM programme?

  12. Preliminary Suggestive Map for Project Activities

  13. Area of fruit, Fruit fly Infestation and IPM Practices in Cambodia

  14. Preliminary Suggestive Map for Project Activities for Cambodia

  15. Area of fruit, Fruit fly Infestation and IPM Practices in Vietnam

  16. Preliminary Suggestive Map for Project Activities for Vietnam

  17. Area of Vegetables, Melon fly Infestation and IPM Practices in Laos

  18. Preliminary Suggestive Map for Project Activities for Laos

  19. Area of Vegetables, Melon fly Infestation and IPM Practices in Cambodia

  20. Preliminary Suggestive Map for Project Activities for Cambodia

  21. Fruit Fly Presence by fruit types Longan Litchi Guava

  22. Fruit Fly Presence by fruit types Pomelo Custard Apple Common Plum Longan Jujube Guava

  23. Fruit Fly Presence by fruit types Papaya Peach Pear Star Apple Sapota Persimmon

  24. Fruit Fly Presence by fruit types Star fruit Sweet Orange

  25. Mapping Status and Limitations • Infestation data considered is at province level and not actual pest outbreak location. • Extent of damage in crops and the period of information has to be collected for all kind of crops in all province. • Spread of the pests may be linked with environment and climatic condition. Extensive information on land use, soil, climatic factors is needed

  26. Comments and Suggestions? • What analysis could be added to this so as to improve preliminary findings? • What all additional information can be included and used ? • Is it possible to get exact location of incidence of pests? • Any other comments?

  27. Thank You
