Presentation Transcript

  1. Evaluate new attractants in SIT programms Rui Pereira

  2. Jackson trap with trimedlure Standard Extensiveadultmasstrapping

  3. Results • Distribution of the flies • Ratio Sterile:Wild • Wild population levels • Wild population detection

  4. Marked Unmarked Wild Sterile Males

  5. Major faults • Use of florescent dye causes reduced fly • Cost of separating the males

  6. Recent developments • Availability of GSS • Control Programs • Female attractants

  7. Dry traps with female attractants Tephri Traps Traps

  8. Female attractants TCL • Putrescine • Ammonium acetate • Trimetylamine

  9. Females catch are wild If GSS is used

  10. Madeira-Med (1999) • Females released (1.8%) • Traps serviced (5,508) • Females catch (154,035) • Percentage of sterile females (0.66%)

  11. Wild flies

  12. Madeira-Med (Data from 1999)

  13. (wild + sterile) (all wild) Total flies (250) (192) (58) wild= 0.72  (0.72 x 58) = 42 sterile= total – wild  (192 – 42) = 150

  14. Ratio Sterile:Wild

  15. Conclusion:(Advantages of unmarked pupae) • Increase the quality of the flies • Cost reduction • Increase the quality of the work (reduce the risk of allergies)
