Table 2 Trypanosome infection rates in sequential feeds. Flies (Glossina morsitans morsitans) were fed parental (1738G, J10G) or F1 trypanosome clones (F1R1, F1G2) as tenerals or non-tenerals on day 18 according to infection regimes 1–4 and dissected 24–25 days later. Midguts and salivary glands (SG) were scored for the presence of each clone by colour of fluorescence
