Jacek Kamczyc, Cezary Urbanowski, Emilia Pers-Kamczyc
Density, diversity and assemblage structure of Mesostigmata (cohorts Gamasina and Uropodina) were investigated in Scots pine forests differing in forest age (young: 9-40 years and mature: 83-101 years) in which wildfire occurred. This animal group belongs to the dominant acarine predators playing a crucial role in soil food webs and being important as biological control agents. In total, six forests (three within young and three within mature stands) were inspected in Puszcza Knyszyńska Forest Complex in May 2015...

Tobias Pfingstl, Julia Baumann
The intertidal oribatid mite species Alismobates galapagoensis and Litoribates caelestis occur on the archipelago of Galápagos. To test for morphological variation between populations of different islands, a comprehensive morphometric study was performed. Four A. galapagoensis populations from the islands Bartolomé, Isabela, Santa Cruz and San Cristobal, as well as two L. caelestis populations from Bartolomé and Santa Cruz were investigated. The L. caelestis populations did not show any significant differences whereas the A...

Ricardo García-Jiménez, Jose Luis Horreo, Antonio G Valdecasas
In this work, we compare morphological and molecular data in their ability to distinguish between species of water mites (Acari, Prostigmata, Hydrachnidia). We have focused on the two species of the genus Lebertia inhabiting the island of Madeira. While traditional morphological traits were initially sufficient to distinguish between these two species, the molecular data were more dependable on the kind of analysis carried out. Single arbitrary genetic distance (e.g. a K2P distance below 2%) may lead to the conclusion that the specimens under study belong to the same species...

The cosmopolitan species Rhipicephalus sanguineus s.l. is one of the most widely distributed ticks all over the world. These ectoparasites are vectors of several pathogens and cause significant direct damage to their hosts. The biological success of these ectoparasites has been attributed to their ovaries and salivary glands, organs that ensure their survival in various environmental conditions. The importance of the ovaries in ticks is that, after mating, the individuals are able to lay approximately three thousand eggs...

Ticks and tick-borne diseases are of global importance and can cause serious economic losses to cattle-raising businesses. However, only few attempts have been made to describe the relationships between various cellular immune components and tick counts of, and therefore resistance to, Rhipicephalus microplus. The present study evaluated the late inflammatory cellular response and dermal dendritic cells at the attachment site in naturally presensitized bovines, artificially infested by R. microplus ticks. Twenty-two crossbred (Holstein × Gir) male experimental cattle were artificially infested with approximately 10,000 larvae of R...

Coxiella burnetii is the causative agent of Q fever, a zoonotic disease of public health importance. The role of wildlife and their ticks in the epidemiology of C. burnetii in Kenya is unknown. This study analysed the occurrence and prevalence of the pathogen in wildlife and their ticks at two unique wildlife-livestock interfaces of Laikipia and Maasai Mara National Reserve (MMNR) with the aim to determine the potential risk of transmission to livestock and humans. Blood from 79 and 73 animals in Laikipia and MMNR, respectively, and 756 and 95 ixodid ticks in each of the areas, respectively, was analysed...

László Egyed
In a laboratory experiment (repeated eight times) individuals of six small rodent species were mixed with 500 Ixodes ricinus larvae for 24 h, than over a 3-day-long observation period engorged ticks fallen from individually kept rodents were counted. Forty engorged larvae fell from the hosts, 25% from striped field mice, 32.5% from house mice, 22.5% from common voles, 10% from bank voles, while wood mouse and steppe mouse proved to be almost free of successfully infesting ticks (both 5%). Statistical analysis indicated, that tick burden differed significantly among host species...

Compounds with tick (Ixodes ricinus) repellent properties were isolated from sulfate turpentine consisting of Norway spruce (80%) and Scots pine (20%) from southern Sweden. The turpentine was divided into two fractions by distillation under reduced pressure resulting in one monoterpene hydrocarbon fraction and a residual containing higher boiling terpenoids. The monoterpene fraction was further oxidized with SeO2 to obtain oxygenated monoterpenes with potential tick repellent properties. The oxidized fraction and the high boiling distillation residual were each separated by medium pressure liquid chromatography...

Intraguild predation is the combination of exploitative competition and predation among potential competitors that use similar resources. It has the potential to shape population dynamics and community structure. Although there is much empirical evidence for the occurrence of intraguild predation in natural ecosystems, the study of its effects is mainly limited to short-term microcosm experiments. There is, therefore, certain skepticism about its actual significance in nature. A relevant concern is that there is no consensus regarding criteria to evaluate the possible occurrence of intraguild predation in short-term experiments, and methodological differences may therefore underlie apparent inconsistencies among studies...

The exotic tick Rhipicephalus (Boophilus) microplus was discovered in Ivory Coast in 2007 and then gradually in other countries in West Africa. It is known to induce significant losses in farming and to replace other species of the same genus. In order to contribute to improve health and productivity of cattle in Ivory Coast regarding the emergence of this dreaded tick, a study was conducted to determine the current geographic distribution of the tick R. (B.) microplus and review cattle ticks in general. To this end, 23,460 ticks were collected from 180 farms located throughout the country...

We examined morphological and genetic differences among Aceria spp. inhabiting six Brassicaceae species in Serbia. Five of them have been already mentioned in the literature as original or alternate hosts of Aceria spp. (Berteroa incana (L.) DC., Capsella bursa-pastoris (L.) Medik., Cardamine hirsuta L., Lepidium draba L. and Sisymbrium orientale L.), whereas Aurinia petraea (Ard.) Schur was registered here for the first time as a host for Aceria sp. Results of morphometric analyses indicated clear differentiation of Aceria spp...

Systematic acarological surveys are useful tools in assessing risk to tick-borne infections, especially in areas where consistent clinical surveillance for tick-borne disease is lacking. Our goal was to identify environmental predictors of tick burdens on dogs and tick-borne infectious agents in dog-derived ticks in the Chiriquí Province of western Panama to draw inferences about spatio-temporal variation in human risk to tick-borne diseases. We used a model-selection approach to test the relative importance of elevation, human population size, vegetative cover, and change in landuse on patterns of tick parasitism on dogs...

Ticks are important ectoparasites and vectors of the pathogens that cause disease in humans and animals. At a natural reserve in Ciudad Real (Spain), an uncontrollable infestation of wild animals with Hyalomma lusitanicum (Koch) has been reported by some game reserve owners. Many questions about distribution, abundance, and phenology of this tick in this area remain unanswered. The aim of this study was to determine if temperature and relative humidity affect the questing tick's activity in four species of ticks in a meso-Mediterranean area, especially that of H...

In order to study the function of peroxidase (POD) and polyphenol oxidase (PPO) in cassava resistance to spider mites, we tested the changes of transcription levels and activities of these two protective enzymes in both cassava and Tetranychus urticae (=T. cinnabarinus) during the interaction. The results showed that after damage of the mite-susceptible cassava cultivar BRA900 by T. urticae for 1 and 8 days, the transcription levels of MePOD and MePPO and the activities of POD and PPO showed no significant difference compared with those in undamaged leaves...

Genetic identity and morphological features of a human biting tick, Amblyomma testudinarium, were determined for the first time in Taiwan. Morphological features of adult male and female ticks of Am. testudinarium were observed and photographed by a stereo- microscope. The genetic identity was analyzed by comparing the sequences of mitochondrial 16S ribosomal DNA gene obtained from 18 strains of ticks representing 10 species of Amblyomma, and four outgroup species of Dermacentor and Rhipicephalus ticks. Nine major clades could be easily distinguished by neighbour-joining analysis and were congruent by maximum-parsimony method...

Ricarda Lehmitz, Peter Decker
To make oribatid mites an applicable tool in monitoring programs it is necessary to find a molecular species marker that allows distinct, rapid and easy species identification. In previous studies, the common barcoding sequence COI showed to be too variable to serve as species marker in oribatid mites. The aim of the present study is to evaluate the potential use of the D3 region of the nuclear 28S rDNA gene for species identification. Therefore, we generated a reference DNA library of 28S D3 to identify specimens of the Oribatida from Germany, with focus on species occurring in peatlands being one of the most endangered habitats in Europe...
