THE MECHANICAL TRANSMISSION OF Trypanosoma evansi BY Haematobia minuta (DIPTERA: Mus c idae) AND Hippobosca camelina (DIPTERA: Hippobos c idae) FROM AN INFECTED CAMEL TO A MOUSE AND THE SURVIVAL OF TRYPANOSOMES IN FLY MOUTHPARTS AND GUT

The role of Haematobia minuta Linnaeus and Hippobosca
camelina Leach in the transmission of camel trypanosomiasis
was assessed. In a preliminary survey, there were no trypa
nosomes in the mouth parts or gut of the field collected, H.
minuta and H. camelina, following dissections. H. minuta
mechanically transmitted T. evansi from an infected camel
to mice but H. camelina failed to do so. Results show that
H. minuta may play just a minor role in the transmission
of camel trypanosomiasis as no parasites were found in
the mouth parts and gut of the field collected flies and the
transmission rate was low. Although parasites survived in
the gut of both flies for as long as thirty minutes, the sur
vival of trypanosomes in the mouth parts of both flies was
restrictive as far as mechanical transmission is concerned.
H. camelina failed to transmit T. evansi experimentally
and therefore its importance in the transmission of camel
trypanosomiasis in Northern Kenya was ruled out, unless
by regurgitation. Sub−inoculated homogenates of flies pre
viously fed on an infected camel were infective to Balb C
mice but the significance of this in relation to mechanical
transmission in nature remains unclear
