Seven new species of the Culicoides reticulatus species group are described and illustrated based on specimens from Colombia, Panama and Brazilian states of northern (Amazonas, Pará and Roraima) and southeast region (Rio de Janeiro). The new species are compared with their similar congener, Culicoides reticulatus Lutz, and a systematic key, table with numerical characters to the females of the ...

Objective: The methanol extracts obtained from the seeds of Hyoscyamus niger L. (Solanaceae) were investigated for their antimicrobial activities against the pathogens causing complicated urine tract infections. Methods: The seeds of plant were extracted with aqueous 60% methanol. The extract was screened against urinary tract pathogens (Enterococcus faecalis, Escherichia coli, Klebsiella pneum...

The ornate dog tick (Dermacentor reticulatus) can be found in the temperate zones of Eurasia. Its area of occurrence is divided into east and west distributions, although the area as a whole is expanding. The initial east-west division was most probably associated with the varied climatic profile of Europe, for example, the range of specific mean winter and summer temperatures: the region where...

Full-length mariner-like elements (MLEs) were identified from both a parasitoid wasp, Ascogaster reticulatus, and its moth host, Adoxophyes honmai. MLEs were detected in two related Tortricid moths, but not in another Ascogaster species. The MLEs of A. reticulatus and A. honmai were 97.6% identical in DNA sequence. This high similarity suggests a recent horizontal transfer, probably from the mo...

Several new taxa belonging to the genus Francisella have been described recently. The present study describes the prevalence of Francisella tularensis and Francisella-like endosymbionts (FLE) in ticks collected from Hungary from 2007 to 2009 and characterizes the genetic variability of FLEs. A total of 5402 Ixodid ticks (Ixodes ricinus, I. acuminatus, Dermacentor marginatus, D. reticulatus, Hae...

The present study compares the efficacy of two recent oral ectoparasiticides containing isoxazolines (NexGard(®), containing afoxolaner and administered at a monthly regimen, and Bravecto™ containing fluralaner and administered at a tri-monthly regimen) against Rhipicephalus sanguineus sensu lato and Dermacentor reticulatus ticks on dogs. 24 dogs were randomly allocated to untreated control, Ne...

Investigations of the abundance and seasonal activity of adult D. reticulatus in relation to the eff ect of climatic conditions (temperature, humidity) and the photoperiod on host-seeking behaviour were conducted in eastern Poland (51°25'N) in 1999-2000. D. reticulatus host-seeking activity was observed between the end of March at 5°C temperature and 89% humidity, and the beginning of December ...

Ixodes persulcatus, Ixodes pavlovskyi, and Dermacentor reticulatus ticks inhabiting Western Siberia are responsible for the transmission of a number of etiological agents that cause human and animal tick-borne diseases. Because these ticks are abundant in the suburbs of large cities, agricultural areas, and popular tourist sites and frequently attack people and livestock, data regarding the mic...
