Non-insecticidal Control of Buffalo Fly using Behaviour Modifying Systems
The capacity of UV light to attract released flies and to remove flies from animals was demonstrated in the Behavioural Observation Facility for Flies (BOFF). Experiments were also conducted outdoors using both light and sunlight. This work led eventually to the development of a prototype of a new system, which enables effective removal of flies on animals through a simple process.
The responses of buffalo flies to different coloured targets combined with attractants were also measured in the BOFF. Target colour did influence these responses. Two field experiments were carried out where the fly burdens on animals in control and treated groups were monitored. The treatment group was subjecte to the newly developed process and was kept in a paddock away from the control group.
Fly numbers on the animals in both groups were recorded daily. In both experiments, substantial reductions in the fly populations on1he treated groups compared to the control group were recorded. In the first experiment, the treatment group mean fly burden was about 15% of the control group at the end of week 2. In the second experiment, the treatment group carried about 25% of the flies present in the control group at the end of the three-week trial. Such reductions in fly burdens are considered very encouraging, particularly in view of the limited duration and area of these trials.
The results presented in this report on the reductions of buffalo flies on animals using the newly developed process, indicate the potential of such a system for non-insecticidal control of buffalo flies and justify further R&D work on this system.
