Scanning Electron Microscopy (SEM) analysis and biological control of Ixodes ricinus using entomopathogenic fungi
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...

متن کاملUltra-high resolution scanning electron microscopy of biological materials.
In recent years, several ultrahigh resolution scanning electron microscopes (SEM) were successively developed. They were all equipped with a field emission electron gun and an objective lens with a short focal length, and showed a resolution better than 1 nm. With such instrument, not only intracellular structures but also virus, bacteriophages, and biological macromolecules were clearly observ...

متن کاملScanning ultrafast electron microscopy.
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode. Here, we report the development of scanning ultrafast electron microscopy using a f...
