Abstract

Variation in susceptibility to infection with cultured promastigotes of was detected among 3 different geographic strains (ISRAEL, EGYPT, and INDIA) of the sand fly . The ISRAEL strain showed the greatest susceptibility and was chosen for subsequent genetic selection experiments. After 13 generations of genetic selection in this strain, a stable refractory line was obtained in which only 7.5% of the insects could be infected. A highly susceptible line was also obtained in 5 generations of selection. Infection rates in the susceptible line were stabilized at about 94%. A description of the selection process and characteristics of the 2 lines are given.
