Blood meal sources of Glossina pallidipes and G. longipennis (Diptera: Glossinidae) in Nguruman, southwest Kenya.

Abstract

In total, 1,952 Glossina pallidipes Austen and 1,098 G. longipennis Corti adults were collected in forest and savanna habitat in Nguruman, southwestern Kenya, by NG2G traps during the dry season of 1992. Of these, 339 individuals (11.1%) had blood meals, of which 155 (45.7%) were identified by direct enzyme-linked immunosorbent assay. The most frequent blood meal source was bushbuck, followed by ostrich, elephant, buffalo, and warthog. Few meals were taken from cattle. The findings of frequent blood meals from ostriches is new for G. pallidipes and may indicate that ostriches are an important host. More detailed work on the role of ostriches in the epidemiology of trypanosomiasis is required.
