We investigated effects of temperature, at 70% RH, on the reproductive parameters of the parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae). The lowest fecundity (21) was at 35 degrees C and the highest (41) at 27.5 degrees C. At 22.5, 25, and 27.5 degrees C, peak oviposition rates (eggs/female/week) occurred in week 3 and were 4.7, 6.6, and 7.8, respectively; also 5...

Tick cell lines play an important role in research on ticks and tick-borne pathogenic and symbiotic microorganisms. In an attempt to derive continuous Dermacentor reticulatus cell lines, embryo-derived primary cell cultures were set up from eggs laid by field ticks originally collected as unfed adults in The Netherlands and maintained for up to 16 months. After several months, it became evident...

The aim of the present work was to determine whether Dermacentor reticulatus (Fabricius), tick species common in eastern Poland could be infected with Toxoplasma gondii (Nicolle et Manceaux, 1908). A total of 664 unfed D. reticulatus ticks were collected from six localities of Lublin province (eastern Poland) within the framework of study for the presence of bacterial, viral and parasitological...

Medicinally important five Phyllanthus species viz. P. acidus (L.) Skeels, emblica L. (small fruit form), (large niruri L., reticulatus Poir. and urinaria were cytogenetically studied through orcein-staining for authentic characterization. This genus showed variation in somatic chromosome numbers such as 2n=2x=26 (x=13) acidus, reticulatus, 2n=6x=48 (x=8) 2n=10x=100 (x=10) (both small large for...

Cell suspension of Hyoscyamus a/bus L. were investigated for growth and production of tropane alkaloids in three different media. The effects of sucrose concentration and initial pH were also studied. 2,4Dichlorophenoxyacetic acid and 1% sucrose enhanced the production of tropane alkaloids. The percent of alkaloids (0.75%) was higher than in the cultivated plant (0.352 %).

Within the family Solanaceae, tribe Hyoscyameae comprises eight genera distributed across Eurasia. Despite a few attempts to understand relationships within this tribe, affiliations among most remain unresolved. Recently, complete chloroplast genomes from several species of were published, enabling phylogenomic inferences. We sequenced plastome Scopolia carniolica, second genus be reported. Gen...

The interaction between pathogen and tick vector seems to be crucial for vector-borne pathogens. For instance, Borrelia burgdorferi s.l., the Lyme disease agent, must overcome at least two main barriers in the tick vector body to be effectively transmitted: the midgut and the salivary glands. It has been found that salivary gland extract (SGE) of ixodid ticks affects the immune system of verteb...

A survey was carried out to investigate the occurrence of hard tick species (Acari: Ixodidae) infesting domestic dogs in Hungary. Forty veterinary clinics from a wide geographical area were asked to collect hard ticks from dogs and to complete a questionnaire. In total, 25 veterinary clinics submitted 900 ticks from 310 dogs. Intensity of infestation ranged from one to 78 per dog. The most pref...
