H9N2 avian influenza virus has been circulating widely in birds, with occasional infection among humans. Poultry workers are considered to be at high risk of infection with avian influenza due to their frequent exposure to chickens, but the frequency of H9N2 avian influenza virus infections among them is still indistinct. This study was carried out in order(More)
The complete spermathecae of 13 species of Larroussius were dissected and examined. The base of the duct of 4 species (aculeatus, guggisbergi, tobbi, wui) is bell-shaped: they are easily distinguished by differences in shape. Five other species (perniciosus, pedifer, longicuspis, perfiliewi, galilaeus) have lateral structures at the base of the duct: slight(More)
Females of a laboratory colony of Phlebotomus papatasi from Kabul were fed through a membrane on a high dose of amastigotes of Leishmania tropica from the same place. Less than one-third of the flies became infected and only 6% developed heavy infections of the stomodaeal valve. From these observations, and previous studies by other workers, it is concluded(More)
Descriptions are given of armatures in the genital atria of females of the two morphologically similar sandfly species, Phlebotomus papatasi and P. duboscqi. The species are distinguishable by the size and shape of the armature, the grouping of the spines in the armature and the length and shape of the spines. These characters have been shown to separate(More)
Changes in appearance of the accessory glands (AG), ovaries (OV) and the absence or presence of crease marks at the edges of the genital atrium armature (GA) were compared as methods to age-grade female laboratory-bred (Lutzomyia migonei) and wild-caught (Lu.youngi, Lu.spinicrassa, Lu.ovallesi) Neotropical sandflies. Dissections at different physiological(More)
A new species of the sandfly subgenus Paraphlebotomus Theodor from Kenya is described and named Phlebotomus mireillae. The type locality is Utut Reserve, near Gilgil, Nakuru District. The description is based on 10 males and 10 females reared from individual egg batches of wild-caught females. Males of the new species differ from nine other species of the(More)
The six species of phlebotomine sandflies of the subgenus Larroussius recorded in Kenya are Phlebotomus aculeatus, P. elgonensis, P. guggisbergi, P. longipes, P. orientalis and P. pedifer. Five are proven vectors of leishmaniasis in that country or elsewhere. Males of all six can be identified by the morphology of the aedeagus or the number and position of(More)
The shape and size of the genital atria of 17 phlebotomine sandflies from Venezuela were examined. The atria were found to express constant characters among individuals of the same species and to be sufficiently different between species to allow taxonomic separation. The spines on the genital armature are described and the characters that can be used to(More)
Sandflies collected in Kitum cave on the Kenyan side of Mount Elgon were identified as Phlebotomus (Larroussius) elgonensis Ngoka, Madel and Mutinga, a species synonymized with P. (L.) aculeatus Lewis, Minter and Ashford, by D. J. Lewis. A comparison of the flies from Kitum cave with P. aculeatus from Lake Elmentaita, Kenya, shows marked differences in the(More)
