Fig. 1From: Dynamics of gamete production and mating in the parasitic protist Trypanosoma brucei Experimental design. Tsetse flies were fed red (R) and green (G) fluorescent T. b. brucei clones in three different regimes: Teneral, together in the first bloodmeal as newly-emerged flies; Non-teneral, together on day 18; or Sequential, R or G on day 0, followed by the other colour on day 18. Flies were assigned to each treatment from the same batch of emergents and all flies received an infected or uninfected bloodmeal on the same day (day 0); non-teneral and sequential groups also received an infected bloodmeal on day 18; otherwise, flies were fed sterile horse blood (black arrows) until dissectionBack to article page
