Table 1 Trypanosome infection in proboscis. Results for 86 flies infected with Trypanosoma congolense savannah (results from strains Gam2, WG81 and 1/148 combined)

Highest density of trypanosomes^a	No.	%
1. Distal tip	8	9
2. Mid region	7	8
3. Proximal region	41	48
Equal density regions 1 and 2	5	6
Equal density regions 1 and 3	1	1
Equal density regions 2 and 3	15	17
Equal density regions 1, 2 and 3	9	10
Total	86

^aEach labrum was scored for density of infection in three regions of approximately equal length excluding the bulb: 1, Distal tip; 2, Mid-region; 3, Proximal region closest to the bulb
