Review of the genus Haba Semenov, 1954 (Hymenoptera Chrysididae) with the key to species.

Four species of the genus Haba are reviewed. New combination is proposed for Haba colonialis (Mocsáry, 1911), comb. nov.

Chrysura izadiae sp. nov., a new cuckoo wasp (Hymenoptera, Chrysididae) from Southern Iran.

Chrysura Dahlbom, 1845 is the second largest genus in the Chrysidini tribe. It is essentially a Holarctic genus composed of over 100 species. The largest diversity is observed in the western Palaearctic Region.

Epidemiology of Leishmania infantum, Toxoplasma gondii, and Neospora caninum in Rattus rattus in absence of domestic reservoir and definitive hosts.

Isolated environments are privileged settings to study transmission of infection. Montecristo is a small island where no wild or domestic carnivores are present. Invasive Black rats Rattus rattus (n=78) were captured and tested by PCR for Leishmania infantum, Toxoplasma gondii and Neospora caninum.

To the knowledge of cuckoo wasps (Hymenoptera: Chrysididae) of the Balearic Archipelago, Spain.

The Chrysididae of the Balearic Archipelago were studied by operating four Malaise traps in the Mallorca and Menorca Islands. Traps captured 98 individuals belonging to 19 species. Including all available data from literature, the number of species in this archipelago rise to 34.

Inclusive double-pomeron exchange at the fermilab tevatron p p collider.

We report results from a study of events with a double-Pomeron exchange topology produced in p p collisions at sqrt[s]=1800 GeV. The events are characterized by a leading antiproton and a large rapidity gap on the outgoing proton side. We find that the differential production cross section agrees in shape with predictions based on Regge theory and factorization, and that the ratio of double-Pomeron exchange to single diffractive production rates is relatively unsuppressed as compared to the O(10) suppression factor previously measured in single diffractive production.
