Metacyclic promastigotes were observed in s. v. of all sand flies examined
aBlood-fed sand flies/exposed sand flies ×100
bDissected sand flies/total fed flies ×100
c Leishmania positive sand flies/dissected sand flies ×100
dMaturity of infection is estimated as the percentage of sand flies with promastigotes in the stomodeal valve (s. v.)
