Breeding protocol for the sand fly Nyssomyia neivai (Diptera: Psychodidae) in laboratory conditions.

abstract：:Leishmania is transmitted in the presence of sand fly saliva. Protective immunity generated by saliva has encouraged identification of a vector salivary-based vaccine. Previous studies have shown that immunization with LJM11, a salivary protein from Lutzomyia longipalpis, is able to induce a Th1 immune response and pr...
