*apparent false positives.
Numbers of specimens and percentages positive or negative for Plasmodium falciparum, as determined by PCR, across all treatments, for anterior and posterior portions of specimens of Anopheles stephensi, at different stages of infection (Oos only = oocysts only, 6–7 days p.i.; Spz + Oos = sporozoites and oocysts, 14 days p.i.), and different bisection locations (A, B, C, see Figure 1).
