Summary: Arthropods are involved in the transmission of parasitic and
viral agents that cause devastating diseases in animals and
plants. Effective control strategies for many of these diseases
still rely on the elimination or reduction of vector insect popu-
lations. In addition to these pathogenic organisms, arthropods
are rich in microbes that are symbiotic in their associations and
are often necessary for the fecundity and viability of their hosts.
Because the viability of the host often depends on these obligate
symbionts, and because these organisms often live in close
proximity to disease-causing pathogens, they have been of in-
terest to applied biologists as a potential means to genetically
manipulate populations of pest species. As knowledge on these
symbiotic associations accumulates from distantly related
insect taxa, conserved mechanisms for their transmission
and evolutionary histories are beginning to emerge. Here,
Serap Aksoy summarizes current knowledge on the functional
and evolutionary biology of the multiple symbionts harbored in
the medically and agriculturally important insect group, tsetse,
and their potential role in the control of trypanosomiasis.
Tsetse (Diptera: Glossinidae) are the vectors of African
