Susceptibility to L. major infection during the first and second bloodmeal. P. duboscqi females were infected (10⁶ promastigotes/ml) during the first or second bloodmeal. Infection rates and intensities of infection were evaluated microscopically in sand fly midguts on days 2, 6, and 9 PI, and infections were classified into three categories: light (< 100 parasites/gut), moderate (100–1000 parasites/gut), or heavy (> 1000 parasites/gut). Numbers above the bars indicate the number of dissected females.
