abstract the syrphidae family (known as hover flies or flower flies) is one of the largest families of diptera with almost 6000 species. adult flies feed on nectar and pollen of flowers and they are crucial agent in pollinating process. the larvae of many species of syrphidae are predators of aphids and play an important role in biological control of pests. in the following faunestic investigat...

The genera Eumerus and Merodon (Diptera: Syrphidae) have a high taxonomic diversity (300+ species altogether), but life histories of most species are unknown. In addition, these hoverfly genera are recognised to be pests (ornamental plants and vegetable crops). In this paper, early stages of four hoverfly species are described, Eumerus hungaricus Szilády, 1940, Eumerus nudus Loew, 1848 and Mero...

The results of the hoverfly (Syrphidae) collection by the ‘Malloch Society’ on the Greek island of Lesvos are presented. Fieldwork took place from February to March 2006 and from May to June 2010. An account of 66 species from 28 genera is provided including two species new to science, five species new to Greece and data for several rarely recorded species. We describe Eumerus armatus Ricarte a...

Plectranthus is one of the most representative genera of Lamiaceae family. In this study, the essential oils from Plectranthus amboinicus, Plectranthus ornatus, and Plectranthus barbatus were investigated for their chemical composition and antimicrobial and modulatory activities. The major components found were carvacrol (54.4%-P. amboinicus) and eugenol (22.9%-P. ornatus e 25.1%-P. barbatus). ...

Five new species of the feather mite genus Protolichus Trouessart, 1884 (Astigmata, Pterolichidae) are described from parrots of the subfamily Loriinae (Psittaciformes: Psittacidae): Protolichus ornatus sp. n. from Trichoglossus ornatus (Linnaeus, 1758), P. lorinus sp. n. from Lorius lory (Linnaeus, 1758), P. placentis sp. n. from Charmosyna placentis (Temminck, 1835), P. pulchellae sp. n. from...

Spasskyellina mandi n. sp. (Proteocephalidea: Monticelliidae) is described from the Siluriform fish Pimelodus ornatus Kner, 1857, caught in the Paraná River, Paraná, Brazil. The new species differs from other species of the same genus mainly by a fewer number of testes and by a larger osmoregulatory canal. This is the second species of proteocephalidean cestode collected in P. ornatus.

The main neurotoxic components, toxins Hydrophis ornatus a and Hydrophis lapemoides a, were isolated from the venoms of the sea snakes Hydrophis ornatus and Hydrophis lapemoides respectively. The amino acid sequence of toxin Hydrophis ornatus a was deduced to be identical with that of toxin Astrotia stokesii a [Maeda & Tamiya (1978) Biochem. J. 175, 507-517] on the basis of identity of the tryp...

The diversity in the Eumerus tricolor group, largest group within genus Southeast Europe, is investigated. Two new, locally distributed species are described, E. crispus Vujić & Grković, sp. n. from Serbia and nigrorufus Grković Vujić, Montenegro. In addition to European members, one related arctus van Steenis, described Switzerland. We designate lectotypes for ovatus Loew, 1848, tarsal...
