GENETIC IDENTFICTATION OF INDIVIDUAL HOST
BLOOD FROM AFRICAN TSESTE FLIES |
This on-going project was initiated in 1997 at Trent University with Dr S. Schoffield and Dr S. Torr of the Natural Resources Institute (NRI), Greenwich, UK. |

The Wildlife Forensic DNA Laboratory extracts DNA from tstetse fly blood meals that have been collected in experimental fenced and netted enclosures in Tanzania. Individual-specific DNA profiles are generated using bovine-specific microsatellite loci that provide the identification of single or multiple blood meals by a tsetse and specifically which cattle have been fed upon. The objective of this study is to determine the feeding preference of African tsetse. In addition to the academic interest in biting-fly feeding behaviour, the applied management implications of this study are that by identifying tsetse preferred cattle recommendations can be made to local farmers as to which cattle should be immunised against Trypsanimosis, sleepling sickness. 1,000,000 people and cattle are infected by Tsetse flies every year in Africa. Approximately 500 blood meals were analysed in 1999-2000 and approximately 750 were profiled in 2000-2001. |
