Species richness and abundance of wild tsetse flies collected from selected human-wildlife-livestock interface in Tanzania
The successful control of tsetse flies largely depends on understanding of the species available and abundance. This study assessed the species richness, abundance and apparent density of wild collected tsetse flies from selected human-wildlife-livestock interface in Tanzania. Seasonal trapping using baited NZI, Pyramidal and Biconical traps was done across selected wards. Traps were set at 200 m apart, emptied after every 24 h then rotated to the next sites after 72 h. Collected flies were identified morphologically and letter confirmed using the Polymerase Chain Reaction (PCR). Only two Glossina species; Glossina pallidipes (n = 371; 47.32 %) and Glossina morsitans morsitans (n = 413; 52.68 %) were identified. Among them, 96 flies (80 Female, 16 Male) were blood fed; 57(48 Female and 9 Male) G. pallidipes and 39(32 Female and 7 Male) G.m. morsitans. Tsetse fly abundance varied across wards (χ2 = 4.597, df = 1, p = 0.032), villages (χ2 = 9.491, df = 3, p = 0.023), habitats (χ2 = 17.239, df = 2, p < 0.001), months (χ2 = 13.507, df = 3, p = 0.004) and deployed traps (χ2 = 6.348, df = 2, p = 0.04). About 78.82 % of the total catch occurred in Kisaki ward (n = 618; p < 0.001) and 21.17 % (n = 166; p = 0.032) in Bwakila chini. Similarly, 62.37 % of the catch occurred in Mbojoge village. NZI traps (n = 422; 54 %; 4.98 FTD) were most successful traps. Moreover, 78.06 % of the catch occurred in bushed grassland habitat (n = 612; 55.41 FTD) while 5.48 % in farmland (n = 43; 7.17 FTD). This study recommends NZI and Pyramidal traps for tsetse flies control at the interface and proposes wet season as appropriate time for successful trapping of the flies. Finally, it attracts a need for assessing tsetse flies' blood meal sources and the infection status to establish the prevalence to inform existing trypanosome control programs.
期刊介绍:
Parasite Epidemiology and Control is an Open Access journal. There is an increasing amount of research in the parasitology area that analyses the patterns, causes, and effects of health and disease conditions in defined populations. This epidemiology of parasite infectious diseases is predominantly studied in human populations but also spans other major hosts of parasitic infections and as such this journal will have a broad remit. We will focus on the major areas of epidemiological study including disease etiology, disease surveillance, drug resistance and geographical spread and screening, biomonitoring, and comparisons of treatment effects in clinical trials for both human and other animals. We will also look at the epidemiology and control of vector insects. The journal will also cover the use of geographic information systems (Epi-GIS) for epidemiological surveillance which is a rapidly growing area of research in infectious diseases. Molecular epidemiological approaches are also particularly encouraged.
