Protective netting, an additional method for the integrated control of livestock trypanosomosis in KwaZulu-Natal province, South Africa

Abstract

Studies were conducted in KwaZulu-Natal, South Africa, to evaluate the effectiveness of netting in preventing Glossina austeni and Glossina brevipalpis from entering H-traps. Results indicated that a net of 1.5 m in height was effective in reducing catches of G. austeni by 59.6% and catches of G. brevipalpis by 80.9%. Increasing the net height to 2.5 m, reduced catches by 96.6% and 100% for G. brevipalpis and G. austeni, respectively. Nets of this height also reduced catches of horse flies by 55%. Although the potential use of protective netting has limitations in tsetse-infested areas of rural northern KwaZulu-Natal, it is a low-technology method that can be used as part of integrated disease management strategies.
