ABSTRACI' The feeding behavior of Lutzomyia longipalpis was ellsmined on uninfected mice and on mice infected with Leishmania mexicana ama%onensis. Feeding was limited to areas of exposed skin and included the ears, eyelids, feet, nose, and tail. The incidence of landing on specific sites was positively correlated with the surface area of the individual sites on both infected (r = +0.91) and uninfected (r = +0.96) mice, suggesting that selection of landing sites occurred randomly. Probing on infected mice was not a random event. Pref­ enmtial probing by Lutzomyia longipalplJ on cutaneous lesions of infected mice resulted in a frequency of feeding higher than ell...
