Abstract

Baseline and control intervention entomological and parasitological studies were conducted from September 2016 to February 2018 with the intended purpose of evaluating the effectiveness of implemented strategic trypanosomosis and vector control activities. The baseline and control intervention entomological studies compared and revealed a decline in the overall apparent fly density from 2.61 flies/trap/day during the baseline study to 1.68 flies/trap/day after the control intervention, representing a reduction of 64.37%. Additionally, the mean daily catch per trap showed a significant reduction from 5.23 ± 1.58 to 3.35 ± 1.58 (mean catch ± SD). The comparison of baseline and control study results showed a significant decline in the overall prevalence of bovine trypanosomosis, from 7.91% to 4.81% (likelihood ratio = 13.49, P ≤ 0.00), corresponding to a reduction of 60.81%. Furthermore, a better herd mean packed cell volume (PCV) was observed during the control intervention study (22.53 ± 4.48 and 25.68 ± 4.04, mean PCV ± SD) compared to the baseline (21.87 ± 4.57 and 25.41 ± 4.27, mean PCV ± SD) in parasite-infected cattle. Therefore, the results of the study clearly showed that the implemented vector control activity, specifically the application of deltamethrin insecticides on stationary attractive devices (targets), ground sprays, and live bait techniques, effectively suppressed both the vector population (Glossina flies) and parasite prevalence (trypanosomiasis) during the study period.

通过使用固定式吸引装置（目标物）、地面喷洒和活饵技术，在比尔比尔河流域使用溴氰菊酯类杀虫剂，实施了战略性锥虫病和病媒控制活动

2016年9月至2018年2月进行了基线和控制干预昆虫学和寄生虫学研究，目的是评估实施的战略锥虫病和病媒控制活动的有效性。基线和对照干预昆虫学研究比较发现，总体表观蝇密度从基线研究期间的2.61只/诱蚊器/天下降到对照干预后的1.68只/诱蚊器/天，减少了64.37%。平均日捕获量由5.23±1.58降至3.35±1.58（平均捕获量±SD）。基线和对照研究结果的比较显示，牛锥虫病的总体患病率从7.91%下降到4.81%（似然比= 13.49,P≤0.00），下降了60.81%。此外，在对照干预研究中，感染寄生虫的牛群平均堆积细胞体积（PCV）（22.53±4.48和25.68±4.04，平均PCV±SD）优于基线（21.87±4.57和25.41±4.27，平均PCV±SD）。因此，研究结果清楚地表明，在研究期间实施的媒介控制活动，特别是溴氰菊酯杀虫剂在固定吸引装置（目标）上的应用，地面喷洒和活饵技术，有效地抑制了媒介种群（舌蝇）和寄生虫流行（锥虫病）。

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.
