Comparative Study of the Survival and Productivity of <i>Glossina palpalis </i><i>gambiensis</i> Fed with Bovine Blood Collected at the Bobo-Dioulasso and Koubri Slaughterhouses in Burkina Faso

Maintaining a high production rate by producing good quality pupae of Glossina palpalis gambiensis is the main challenge of colony management during mass rearing process. Feeding tsetse flies with high-quality bovine blood is the better solution for resolving the problem. The overall objective of this study was to contribute to the improvement of tsetse fly feeding quality in tsetse fly mass rearing through the evaluation of tsetse fly productivity. To achieve this goal, 2 batches of 05 cages each containing 150 females and 50 males of G. palpalis gambiensis were set up. Each batch of tsetse was fed with blood from either the Bobo Dioulasso or Koubri slaughterhouse. The parameters evaluated were: survival, pupal weight and number of pupae produced per initial female. Survival was not significantly influenced by the origin of the blood used. On the other hand, the number of pupae per initial female was quite significantly higher with the batch using Koubri blood (p > 0.05). Tsetse flies fed with bovine blood collected at the Koubri abattoir had better survival and productivity parameters than those fed with blood collected at the Bobo-Dioulasso slaughterhouse.
