Though generally considered to be unimportant as vectors, the feeding behaviour of stable flies and related species has been associated with substantial economic as well as interactions between hosts and important vectors like tsetse. We discuss here the responses of Stomoxyinae to host-based kairomones, in the laboratory and the field. Further, we consider the interplay between these Diptera, other vectors and their common hosts as it relates to disease epidemiology, and possible control strategies. In general, we find that the behavioural responses of stable flies to certain host odours in the laboratory are similar to other groups of fast moving Diptera that blood feed (e.g., tsetse), i.e. activity increases and flights are steered upwind. While several compounds have been associated with increased trap catch of Stomoxyinae in the field, the only compound where this effect has been consistently shown is CO2. We conclude that other odours might not be especially important as regards stable fly orientation to hosts, and further suggest that, to date, the utility of odour-based baits to sample or control stable flies has not been convincingly demonstrated. Finally, we describe the interplay between Stomoxyinae and their hosts, highlighting the role that their feeding might play in the epidemiology of animal trypanosomiasis, as well as the substantial variability evident between hosts as regards: stable fly burden, defensive responses and the feeding success of the attacking insects. Related to this, we describe some of the potential practical applications that might come from a better understanding of the interrelationship between Stomoxys species and their hosts.
