The distribution and abundance of Glossina austeni Newstead and Glossina brevipalpis Newstead (Diptera: Glossinidae) were studied in the three main vegetation types in Zululand, KwaZulu-Natal, South Africa. During a period of 12 months, a trap transect consisting of 38 H-traps traversing the three vegetation types was monitored. The Index of Apparent Abundance (IAA) for G. brevipalpis was high in indigenous forest and open grassland but lower in exotic plantations. Glossina austeni, on the other hand, was captured mainly in or adjacent to indigenous forest. The seasonal trend in the IAA did not differ between vegetation types. The findings on the distribution of G. brevipalpis are in contrast with the historic records. Historically, this species was considered to be restricted to areas with a dense overhead canopy and high relative humidity. The repercussions of these findings for the epidemiology of livestock trypanosomiasis and the control of tsetse in Zululand are discussed.
在南非夸祖鲁 - 纳塔尔省祖鲁兰的三种主要植被类型中，对奥氏采采蝇（Glossina austeni Newstead）和短须采采蝇（Glossina brevipalpis Newstead）（双翅目：采采蝇科）的分布和数量进行了研究。在12个月的时间里，对一个由38个H型诱捕器组成、横穿这三种植被类型的诱捕样带进行了监测。短须采采蝇的表观丰度指数（IAA）在原生森林和开阔草原中较高，而在人工外来种植园中较低。另一方面，奥氏采采蝇主要在原生森林内或其附近被捕获。IAA的季节趋势在不同植被类型之间没有差异。短须采采蝇分布的研究结果与历史记录形成对比。从历史上看，该物种被认为局限于头顶树冠茂密且相对湿度较高的地区。讨论了这些发现对祖鲁兰家畜锥虫病流行病学和采采蝇控制的影响。
