Mitochondrial DNA Intraspecific Variability in Sergentomyia minuta (Diptera: Psychodidae)

Recently, there has been growing interest in analysis of the geographical variation between populations of different Phlebotomus spp. and American sand flies by comparing the sequences of various genes. However, little is known about the genetic structure of the genus Sergentomyia França & Parrot. No study has been carried out on Sergentomyia minuta Rondani. Most […]

Rotation of the external genitalia in male Phlebotomine sand flies (Diptera, Psychodidae) in laboratory conditions and in captured specimens in Algarve, Portugal

Protozoal parasites are the causative agents of many insect-borne infectious diseases worldwide with impact on human and animal health. Leishmaniasis is caused by Leishmania spp. and transmitted by female Phlebotomine sand flies. In Portugal, two species of Phlebotomus (Larroussius), namely Phlebotomus perniciosus and Phlebotomus ariasi are the proven vectors of Leishmania infantum. Phlebotomine females and […]

Genetic structure of Phlebotomus (Larroussius) ariasi populations, the vector of Leishmania infantum in the western Mediterranean: epidemiological implications

In recent years there has been growing interest in analyzing the geographical variations between populations of different Phlebotomus spp. by comparing the sequences of various genes. However, little is known about the genetic structure of Phlebotomus ariasi. In this study, we were able to sequence a fragment of the mitochondrial Cyt b gene in 133 […]

Entomological and ecological studies in a new potential zoonotic leishmaniasis focus in Torres Novas municipality, Central Region, Portugal

In Portugal human and canine leishmaniasis are caused by Leishmania infantum, and Phlebotomus perniciosus and P. ariasi are the proven vectors. Three main foci were identified in eighty’s decade: Trás-os-Montes and Alto Douro region, Lisbon region and Algarve region, but according to OnLeish observatory data, canine leishmaniasis cases have been reported from several other regions, for which sand fly species and their infection rates are unknown.
