Avaliação da atractividade de alvos contra moscas hematófagas no distrito de Matutuíne, província de Maputo

Abstract

Blood-sucking flies constitute one of the main sanitary and productive challenges for livestock in Africa, since in addition to causing direct losses through blood loss and stress in animals, they act as mechanical or biological vectors of various pathogens, including protozoa, bacteria, and viruses. This study aimed to evaluate the efficiency of different target models, made of fabric and polyethylene, in capturing blood-sucking flies in the Matutuíne district, Mozambique. The experiment was carried out using a 4×4 Latin Square design. Four targets were tested: a small West African target, a small target, a completely blue polyethylene target, and a blue and white target. Captures were statistically analyzed by ANOVA and Tukey's test. The results showed that the genus Stomoxys (92%) was predominant, followed by Hematobosca (6%) and Haematobia (1%). At the Gala Station, the all-blue polyethylene target showed greater efficiency, significantly outperforming the blue and white target and the small target. However, there was no significant difference between the all-blue target and the small West African target. It is concluded that both polyethylene material and cotton fabrics can be effective in capturing hematophagous flies, but efficiency depends on the target model, environment, and field positioning. The results indicate the all-blue polyethylene target as the most efficient alternative for use in monitoring and control programs for these flies.(TRADUÇAO NOSSA)
