Efficient Application of GIS in Fruit Fly Eradication

Implementing GIS technology in Medfly campaigns in Mendoza, Argentina, from 1990 to 2001 for control and eradication operations. Activities included trapping, fruit sampling, SIT, chemical, and cultural control. Utilization of GIS technology for data management, mapping, and tracking.

  1. PROCEM Program of Control and Eradication of Fruit Flies Applications of GIS (Geographical Information System) MENDOZA ARGENTINA

  2. Medfly Campaigns 1990 to 1992 Objective: Diagnosis Activity: Trapping Number of traps: 1527

  3. First attempts in the use of geographic coordinates Use of cartographical maps Use of graph generators

  4. Medfly Campaigns 1992 to 2001 Objective: Eradication Activities: Monitoring Trapping Fruit sampling Control SIT Chemical Control Cultural control

  5. FRUIT SAMPLING North Oasis: 18,891 East Oasis: 11,283 Central Oasis: 6,810 South Oasis: 15,099 TOTAL : 52,173 SIT CONTROL Total mumber of male medfly realeased: 4.591 bilions. Weekly average (Under release period): 104 milions Aerial release:90% of the area. Land release 10% of the area. Distribution: Over preestablished blocks on the North, East and South Oasis. In the Central Oasis: preventive releases on urban areas CHEMICAL AND CULTURAL CONTROL F.T.D RURAL AREAS OASIS FTD NORTH 0,00397 EAST 0,00207 CENTRAL 0,00010 SOUTH 0,00074 PROCEM - MENDOZA Field Data. Medfly Campaign 1999/2000 TRAPPING North Oasis:Jackson: 803 Mc Phail: 332 % of traps monitored: 96 East Oasis:Jackson: 880 Mc Phail: 260 % of traps monitored: 98 Central Oasis:Jackson: 712 Mc Phail: 204 % of traps monitored: 99 South Oasis:Jackson: 1.105 Mc Phail: 335 % of traps monitored: 99 Total number of traps on duty: 4.631 Total number of trap readings : 228.151

  6. FRUIT SAMPLING North Oasis: 8,861 East Oasis: 5,069 Central Oasis: 6,810 South Oasis: 8,359 TOTAL : 28,683 SIT CONTROL Total mumber of male medfly realeased: 2.668 bilions. Weekly average (Under release period): 102 milions Aerial release:90% of the area. Land release 10% of the area. Distribution: Over preestablished blocks on the North, East and South Oasis.

  7. Geographic Information System (G.I.S) GIS technology is aimed to understand facts which occur on earth using digital images on a computer

  8. Geographic Information System (GIS) EACH DATA POINT IS AN ELEMENT SET UP IN THE SPACE THROUGH A PREDEFINED SYSTEM OF COORDINATES

  9. IMPLEMENTATION • . Rearrangement of existing data bases and set up of new ones • . Election of a system of geographic projection • . Compilation and generation of cartography and digital images • . Election of a GIS system. • . Generation of program rutines to link the different data bases

  10. APLICATIONS FRUIT SAMPLING TRAPPING HOST CENSUS. CHEMICAL AND CULTURAL CONTROL SIT

  11. TRAPPING . Exact location of each trap . Spatial distribution in routes . Dispersion of fly catches . Additional information on individual traps

  12. FRUIT SAMPLING . Coverage and distribution of fruit sampling . Exact place of each sampled location . Additional information of each fruit sample

  13. CENSUS . Host distribution . Location and quantity of each species . Planification and coverage of Chemical and Cultural Control

  14. SIT . Planification of the areas to be released . Control of plane releases . Information about each flight . Analysis of the sterile insect dispersal

  15. Aerial releases Area under SIT: 160,000 ha Strain: TSL Sterile males released per week: 80.000.000 Density : 400- 800 males/ha Type of release: aerial in paper bags Flies per bag: 2,600 males Bags per week: 38,500 Number of blocks: 36 Area of each block: 4,000 – 4,500 ha Frequency: - weekly in 17 blocks - twice a week in 19 urban blocks Airports under operation: 4 Planes under operation: Cessna 172, Cessna 182 Capacity of planes: 700 bags (1,820,000 males) Weekly flights: 55 Average time of each flight: 50 minutes Weekly flight hours: 45 Total flight hours: 2000 Flight conditions: - Altitude: 1.000 feet - Mean speed: 100 miles/hour - Distance between bands: 300 m - Frequency between bags: 4-5 seconds

  16. GIS IS AN EFFICIENT TOOL . For Administration . For Analysis . For Interpretation . For Diagnosis . For Planification . For Execution . For Control Useful on any program of pest control
