Lutzomyia longipalpisPeritrophic Matrix: Formation, Structure, and Chemical Composition [PDF]

Journal of Medical Entomology, 2005
Sandflies are vectors of several pathogens, constituting serious health problems. Lutzomyia longipalpis (Lutz & Neiva, 1912) is the main vector of Leishmania chagasi, agent of visceral leishmaniasis. They synthesize a thick bag-like structure that surrounds the bloodmeal, named peritrophic matrix (PM).
