Feeding Behaviour

Activity Dynamics

Although tsetse flies feed mostly in daylight, feeding does occur at night. Tsetse adults are most active in the morning and in the late afternoon. They rarely fly more than 30 min a day and are known to disperse up to about 1 km/day. Most of the time is spent resting on vegetation. Tsetse flies are more prone to start feeding on calm animals. They fully engorge within about 1-10 min.

The transmission of the different trypanosomes (Trypanosoma brucei and T. congolense in dogs) is occurring during feeding of the tsetse flies.
