Evaluate new attractants in SIT programms Rui Pereira
Jackson trap with trimedlure Standard Extensive adult mass trapping Jackson trap with trimedlure
Results Distribution of the flies Ratio Sterile:Wild Wild population levels Wild population detection
Males Unmarked Marked Wild Sterile
Major faults Use of florescent dye causes reduced fly Cost of separating the males
Recent developments Availability of GSS Control Programs Female attractants
Dry traps with female attractants Tephri Traps
Female attractants TCL Putrescine Ammonium acetate Trimetylamine
If GSS is used Females catch are wild
Madeira-Med (1999) Females released (1.8%) Traps serviced (5,508) Females catch (154,035) Percentage of sterile females (0.66%)
Wild flies
Madeira-Med (Data from 1999)
sterile = total – wild Total flies (250) (all wild) (wild + sterile) (192) (58) wild = 0.72 (0.72 x 58) = 42 sterile = total – wild (192 – 42) = 150
Ratio Sterile:Wild
Conclusion: (Advantages of unmarked pupae) Increase the quality of the flies Cost reduction Increase the quality of the work (reduce the risk of allergies)
