In the last few decades, bark beetle outbreaks have increased in European forests, triggered by extreme weather events, such as drought and windstorms. A core element of integrated pest management to control outbreaks are salvage logging and sanitation felling, i.e., the timely removal or treatment of potential brood material and already infested trees after disturbance events. Associated with these management operations as we...

Microbes associated with the external and internal anatomy of three commercially available predatory mite species— Phytoseiulus persimilis , Typhlodromips (= Amblyseius ) swirskii , and Neoseiulus (= Amblyseius ) cucumeris —were examined using light microscopy, confocal laser scanning microscopy and fluorescence in-situ hybridization (FISH). Four microbe morphotypes were observed on external body regions. These included three...
