TL;DR: Outbreaks of phytophagous forest insects are very often terminated by pathogens, and they are responsible for rapid decline and collapse of local insect populations, therefore, entomopathogens have potential for microbial control programmes through inoculative, inundative or augmentative releases.

TL;DR: In this article, the occurrence and action of natural enemies of bark beetles (Coleoptera: Curculionidae, Scolytinae) are reviewed and the role of these antagonistic agents in bark beetle population dynamics and their potential for use as biological control agents are evaluated based on literature, data from experiments, observations in the field, and from controlled laboratory experiments.

TL;DR: The entomopathogenic fungus Metarhizium anisopliae (Metsch.) Sorokin (Hypocreales: Clavicipitaceae) was applied in maize fields to control the Western Corn Rootworm Diabrotica virGifera virgifera Le Conte.

TL;DR: Pathogens occurring in adult Ips typographus from 15 distinct localities in Austria and in the Czech Republic were registered with exception of pathogenic fungi and bacteria, whereas N. typographi and M. scolyti could be found only in some few specimens.

TL;DR: Four different pathogen species were found in adult beetles from the Forest Demonstration Centre, BOKU University in the course of a 7-year period of investigation.
