The seasonal cycles of reproduction of the dominant copepods Acartia clausi, Temora longicornis, Centropages hamatus, C. typicus and Pseudocalanus spp. were studied at Helgoland Roads, southern North Sea. Egg production rate, clutch size, number of spawning females and prosome length were compared with temperature and phytoplankton concentration. Female A. clausi, T. longicornis and Pseudocalan...

background: the aim of the present study was to induce salivation in haemaphysalis longicornis to increase saliva production and to characterize the collection of proteins present in the collected saliva using on-chip-electrophoresis. methods: saliva of adult female engorged h. longicornis was collected by treatment with 0.2% dopamine hydrochlo­ride. all protein samples were characterized by sd...

Ixodid ticks were collected from 104 wild carnivores belonging to 23 species in various nature reserves and on several farms in all nine provinces of South Africa. Seven feral cats in a nature reserve were also examined. Twenty-four tick species belonging to seven genera were recovered and identified. Amongst these ticks we consider the adults of Haemaphysalis leachi, Haemaphysalis spinulosa, H...

In this study, new and additional records of 15 species the Aleocharinae subfamily (Coleoptera: Staphylinidae) are presented from Türkiye. Among them, Dinusa cretica Assing, 2013 is first record Besides, Autalia longicornis Scheerpeltz, 1947 Maurachelia roubali (Lohse, 1970) Marmara Region Enalodroma hepatica (Erichson, 1839) Aegean reported for time. addition, given many provinces

Species of the shore-fly genus Rhynchopsilopa Hendel from China are reviewed. Four new species (Rhynchopsilopa guangdongensissp. n., Rhynchopsilopa huangkengensissp. n., Rhynchopsilopa jinxiuensissp. n., Rhynchopsilopa shixingensissp. n.) and two previously known species, Rhynchopsilopa longicornis (Okada) and Rhynchopsilopa magnicornis Hendel, are described or redescribed. A key to the species...

Fine-scale water column structure was mimicked in a laboratory plane jet flume to examine responses of the calanoid copepods Temora longicornis and Acartia tonsa to layers consisting of a velocity gradient, density gradient, phytoplankton exudates and food (phytoplankton). Copepods were exposed to isolated layers and combinations of cues as defined by in situ conditions. Behaviors elicited by t...

Particle image velocimetry was used to construct a quasi 3-dimensional image of the flow generated by the feeding appendages of the calanoid copepod Temora longicornis. By scanning layers of flow, detailed information was obtained on flow velocity and velocity gradients. The flow around feeding T. longicornis was laminar, and was symmetrical viewed dorsally, but highly asymmetrical viewed later...

Ticks are serious haematophagus arthropod pests and are only second to mosquitoes as vectors of diseases of humans and animals. The salivary glands of the slower feeding hard ticks such as Haemaphysalis longicornis are a rich source of bioactive molecules and are critical to their biologic success, yet distinct molecules that help prolong parasitism on robust mammalian hosts and achieve blood-m...

Three species of the Laboubeniales from Korea are described. They are new to the mycological flora of Korea. Corethromyces purpurascens on several parts of Ochthephilum densipenne, Laboulbenia barbara on the metasternum of Philonthus longicornis and L. compressa on the elytra of Harpalus tinctulus were found.
