Mating specificity between the molecular forms of An. gambiae in experiments with males of one form in the single female design (females of the same or other form than the male) or mixed female design (females of both forms with males of one form). Specificity index is calculated as the difference in insemination rate between pure and cross –form standardized by the average insemination rate in each experiment replicate. The index ranges from 2 (highest specificity) to −2 (complete preference of the other form), 0 indicates no specificity.
