in the present study, pathogenicity of four native strains of entomopathogenic fungus; metarhizium anisopliae, was studied against adult stage of ixodes ricinus. for this purpose a total number of 180 adult ticks were examined in triplicate. thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. samples were incubated in separate pet...

ticks are vectors of some important arthropod-borne diseases in both fields of veterinary and medicine, such as lyme, tularemia, rocky mountain spotted fever, and some types of encephalitis as well as crimean congo hemorrhagic fever (cchf). iran is known as one of the main foci of cchf in west of asia. this study was conducted in darrehshahr county because of the development of animal husbandry...

BACKGROUND: Ticks are the most important vectors whichtransmit several arthropod-borne diseases such as theileriosis,babesiosis, and anaplasmosis. OBJECTIVES: An epidemiologicalstudy was conducted in Semnan area to determine thecurrent situation of tick infestation in sheep and assess theefficacy of usage of CIS-cypermethrin against tick infestationunder field condition. METHODES: Sampling was ...

We studied the prevalence of Borrelia burgdorferi and the agent of human granulocytic ehrlichiosis (HGE) among questing nymphal and adult Ixodes scapularis ticks of the same generation and the infectivity of wild white-footed mice for ticks feeding on them. The prevalence of B. burgdorferi infection in host-seeking ticks increased less than twofold from nymphal (31% to 33%) to adult (52% to 56%...

Ticks are the most important ectoparasites that responsible for severe economic losses in livestock industry. The use of chemical acaricides is common method used to control ticks livestock. This study was conducted determine efficacy Aspergillus oryzae as an alternative biological agent controlling enhance productivity. A. at different concentrations evaluated against larvae and adults hard ti...

Ticks (Acari: Ixodida) are hematophagous ectoparasites of a wide variety mammals, birds, reptiles, and amphibians, the vectors many pathogenic agents, such as bacteria, protozoa, viruses. The seasonal movement migration birds is one main causes dispersal ticks tick-borne pathogens. Therefore, identification associated with migratory fundamental step to understand ecology infesting evaluate thei...

hyalomma dromedarii (h. dromedarii) is a very characteristic tick with a cosmopolitan distribution, which is closely associated with camels. it is well adapted to extreme dryness of habitat and to camel hosts. in this study, we studied rural husbandry of one-humped camels (dromedaries) in a village in south-west of semnan (biabanak). a total of 163 ticks (94 adults and 67 nymphs) were found on ...

the main objective of this study is to swing krull intersection theorem in primary decomposition of rings and modules to the primary decomposition of soft rings and soft modules. to fulfill this aim several notions like soft prime ideals, soft maximal ideals, soft primary ideals, and soft radical ideals are introduced for a soft ring over a given unitary commutative ring. consequently, the p...
