Phlebotomus martini, a vector of visceral leishmaniasis in Kenya, was colonized in the laboratory for the first time using larval food and other techniques developed at the University of Florida. Phlebotomus duboscqi, a vector of cutaneous leishmaniasis, was discovered in Kenya at a site where Leishmania major has been isolated from rodents. A paper describing the previously unknown male of Sergentomyia blossi from Kenya was completed. The eggs of 5 Lutzomyia species were compared with the aid of the scanning electron microscope. Specific differences in the outer structure of the eggs were found. A new species of Lutzomyia from California and 2 new species from Arizona were discovered. They and 11 other North American Lutzomyia were illustrated in a review paper of the North American fauna. Additional species, including 2 undescribed taxa, were studied from Ecuador, Peru and Surinam. The reference collection of New World Phlebotominae now contains specimens of 280 American species with 66 holotypes and nearly 100 paratypes making it one of the most complete collections in existence. Five Lutzomyia species from the U.S.A. are being maintained in the laboratory 3 of them, L. shannoni, L. diabolica and L. anthophora transmitted Leishmania mexicana Texas strain to hamsters in the laboratory as early as 4 days following the infecting bloodmeal.
