建立了一种酶联免疫吸附试验(EL ISA)来鉴定来自非洲不同生态区的11种Glossina的29 245只野生苍蝇的肠道脊椎动物血液的来源。根据血粉样本的质量，62.8%的样本被鉴定出来，并可被归入宿主组(例如反刍动物)、科(例如牛科)或物种(例如牛)。在物种水平上共鉴定出13145个样品，占总数的44.9%。除了少数例外，目前的结果与早先发表的报告是一致的。奥氏舌象和褐腹海龟对水母(主要是丛林猪)有明显的摄食偏好。Glossina morsitans SSP，主要摄食水母(主要是疣猪)，尽管观察到了局部变异，在一些地区河马或反刍动物取代了疣猪成为主要宿主。林巴克似乎是长须沙鼠和青海沙鼠的主要食物来源。苍耳主要摄食反刍动物(水牛、雄鹿和牛)，但也是重要的宿主，取决于宿主的可获得性和地理位置。河马被鉴定为短腹河马的主要血粉来源。长盘姬蜂的主要宿主是水母(主要是丛林猪)，而不是40年前报道的犀牛。证实了棕榈采采组的机会主义取食行为。结果表明，环境、动物区系和寄主可获得性的变化可能会导致采采蝇取食方式的改变。
An enzyme-linked immunosorbent assay (ELISA) was developed to identify the origin of vertebrate blood in the guts of 29 245 wild-caught flies of eleven Glossina species from various ecological zones of Africa. Depending on the quality of the bloodmeal samples, 62.8% of the samples were identified and could be assigned to a host-group (e.g. ruminant), family (e.g. Bovidae) or species (e.g. Bos spp.). A total of 13 145 samples (44.9%) was identifiable up to the species level. With a few exceptions, the present results are in agreement with earlier published reports. Glossina austeni and G, fuscipleuris seemed to have a distinct feeding preference for Suidae (mainly bushpig). Glossina morsitans ssp, fed mainly on Suidae (mainly warthog), although local variations were observed and in some areas hippopotamus or ruminants replaced the warthog as the main host. Bushbuck seemed to be the principal food source for G. longipalpis and G. fusca. Glossina pallidipes fed mainly on ruminants (buffalo, bushbuck and cattle) but, depending on host availability and location, Suidae were also important hosts. Hippopotamus was identified as the main source of blood-meals for G. brevipalpis. The main hosts for G. longipennis were Suidae (mainly bushpig) and not rhinoceros as had been reported 40 years earlier. The opportunistic feeding behaviour of the palpalis tsetse group was confirmed. The results showed that changes in environment, fauna and host availability may result in modification of tsetse feeding patterns.
