Examination of data on the host preference and trypanosome infection rates of Glossina morsitans morsitans Westwood in Central Zambia showed a marked preference for suids (62%); bovids (17%), 'other mammals' (14%), primates (4%), reptiles (3%) and birds (less than 1%) accounted for the remaining feeds. Trypanosome infection rates in G. m. morsitans were very low (0-3-66%), with higher rates in males; only vivax-type trypanosomes were encountered. The heterogeneity of monthly and seasonal infection rates was not significant; the highest rate was recorded in the hot dry season. There was a significant correlation between age and infection rates (P less than 0-01). A regression of monthly male infection rates and monthly mean temperature showed a significant correlation (P less than 0-05). Possible reasons for the low infection rates are discussed.
对赞比亚中部 morsitans 采采蝇（Glossina morsitans morsitans Westwood）的宿主偏好及锥虫感染率数据进行的研究表明，采采蝇对猪科动物有明显偏好（62%）；牛科动物占比17%，“其他哺乳动物”占14%，灵长类动物占4%，爬行动物占3%，鸟类占比不到1%，其余为其他宿主。morsitans 采采蝇的锥虫感染率非常低（0 - 3.66%），雄性感染率更高；仅发现间日疟原虫型锥虫。月感染率和季节感染率的异质性不显著；最高感染率出现在炎热干燥季节。年龄与感染率之间存在显著相关性（P < 0.01）。每月雄性感染率与月平均温度的回归分析显示存在显著相关性（P < 0.05）。文中讨论了感染率低的可能原因。
