Metarhizium anisopliae as a new pathogen of the spruce bark beetle Ips typographus

  title={Metarhizium anisopliae as a new pathogen of the spruce bark beetle Ips typographus},
  author={Siegried Keller and C E Epper and Beat Wermelinger},
During an outbreak of the bark beetle Ips typographus (L.) induced by the storm "Lothar" (1999), in¬ vestigations of natural enemies and their role in the regulation of this pest insect were carried out at two sites in Switzerland. As a part of this project fungal pathogens were recorded and Metarhizium anisopliae (Metsch.) Sorokin was found for the first time to attack /. typographus. In contrast to Beau¬ veria bassiana (Bals.) Vuill., the percentage of bark beetles infected with M. anisopliae… 
Association of Entomopathogenic Fungi with Exotic Bark Beetles in New Zealand Pine Plantations
Based on morphological characteristics and sequencing data, two species, Metarhizium flavoviride var.
Pathogens of bark beetles (Curculionidae: Scolytinae) and other beetles in Bulgaria
The presence and diversity of beetle pathogens associated with different tree species in Bulgaria was investigated and for the first time, the fungus B. bassiana was reported in Tomicus piniperda, Orthotomicus longicollis, and of the microsporidium Chytridiopsis sp.
Screening of entomopathogenic fungi against the European spruce bark beetle, Dendroctonus micans (Coleoptera: Scolytidae)
B. bassiana isolate KTU-53 appears to be the most promising microbial control agent for biocontrol of D. micans, one of the most serious destructive pests of oriental spruce.
Occurrence of pathogens in Ips typographus (Coleoptera: Curculionidae) and in other spruce bark beetles from the wilderness reserve Dürrenstein (Lower Austria)
The study presents new data on spatial distribution of bark beetle pathogens, on changes in frequency over several years and on their prevalence during different time periods within a year from
Emergence patterns of univoltine and bivoltine Ips typographus (L.) populations and associated natural enemies
Investigation of behavioural traits of the European spruce bark beetle and its predators and parasitoids over several consecutive years found that most predatory beetles and flies spent wintertime with their prey under the bark, while most parasitic wasps emerged in fall.
Synchronous rise and fall of bark beetle and parasitoid populations in windthrow areas
The population level of both groups quickly increased synchronously from the second to the third season, and gradually declined thereafter until the fifth growing season, when the deteriorated phloem quality precludes further bark beetle development.
Untersuchungen über das Auftreten und die Dynamik von Pathogenen bei Ips typographus (Coleoptera, Scolytinae) in Befallsherden unter besonderer Berücksichtigung von Protozoen
The occurrence of pathogens was investigated in the spruce bark beetle Ips typographus L. typographi from three different localities in the Central Plateau of Switz¬ erland within a five-year period, with particular reference to protozoans.
Occurrence of pathogens in populations of Ips typographus, Ips sexdentatus (Coleoptera, Curculionidae, Scolytinae) and Hylobius spp. (Coleoptera, Curculionidae, Curculioninae) from Austria, Poland and France
Differences in occurrence and geographical distribution of these pathogens are discussed with regard to their respective apparent host spectrum and possible ecological requirements.
