| dc.description.abstract | Hematophagous flies like Glossina species, Tabanid, and Stomoxys are economically very important parasitic arthropods affecting domestic animals and humans due to their persistent and painful bites, annoyance, blood-feeding behavior and vectors of pathogens. Despite their great importance of Tabanids and Stomoxys only little information is available about these biting flies in Ethiopia. The little information from Ethiopia on these arthropods was reported by few investigators only at the genus level during their studies on Glossina in some areas. The objectives of the present study were to identify hematophagous fly species affecting domestic animals in the study area, to detect associated blood parasites affecting cattle and to compare catching efficiency of NGU, Biconical and Sticky types of traps in three different districts, viz, Arba Minch, Mirab Abaya and Kucha districts found in Gamo zone. For this purpose, a total of 87 traps were deployed at 29 sites by rotating NGU, Biconical, and sticky panel for sampling the flies, and a total of 409 blood samples were collected from cattle. A total of 2985 flies were collected during the study period were morphologically identified into 2536 (85%) genus Glossina, 234 (7.8%) Stomoxys, and 215 (7.2%) Tabanid. The result of the study demonstrated that the genus Glossina 85% (2536/2536) comprised the majority and the predominant proportion of the collected flies followed by 234 (7.8%) Stomoxys and 215 (7.2%) Tabanid. The results of fly identification revealed the presence of two tsetse species G. pallidipes 79.1% (n= 2005/2536) collected from all the three study districts, however, G. fuscipes 21% (n=531/2536) was collected only from Kucha district. A total of 12 species were twelve species identified were; Ancala. Africana, Atylotus agrestis, Tbanus donaldsoni, T. gratus, T. taeniola variatus, T. taeniatus, T. par, Stomoxys. n. nigra, S. sitiens, S. indica, Glossina pallidipes and G. f. fuscipes. Haematopota and chrysop were identified in to genus level. Apparent densities (AD) of Tabanids, Stomoxys, G. f. fuscipes. Haematopota and chrysop were identified in to genus level. Apparent densities (AD) of Tabanids, Stomoxys, G. f. fuscipes, and G. pallidipes collected from Arba Minch were 1.72, 2.6, 0 and 20.8, respectively. In Mirab Abaya district the apparent densities (AD) of Tabanids, stomoxys, G. f. fuscipes, and G. pallidipes were 0.18, 1.27, 0 and 14.61 whereas in Kucha district the AD of 0.18, 0.3, 8.85 and 0.08 was recorded for Tabanid, Stomoxys, G. f.fuscipes, and G. pallidipes, respectively. The overall catch of G. pallidipes in Arba Minch was significantly higher than the catch in Mirab Abaya (P= 0.0006) and Kucha (P=0.0000) districts. The overall catch of the sticky trap of all fly types was significantly higher than the biconical trap. The Biconical viii trap showed significantly better efficiency (P= < 0.05) than NGU in the catch of Stomoxys and G. f.fuscipes. But the NGU trap showed better catch efficiency (P= < 0.0002) in G.pallidipes and Tabanids than the biconical trap. Of 409 blood samples examined by BCT, 15 were positive for Trypanosomes (n=3 T. vivax, n=12 T.congolensie) and prevalence was 3.4%. The overall mean PCV of cattle positive for trypanosomes was 20.4 which, however, the overall mean PCV of cattle negative for trypanosomes was 28.05. | en_US |
