Observations on the occurrence of pathogens in the bark beetle <i>Ips typographus</i> L. (Col., Scolytidae)

Abstract

Abstract: 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. An Entomopoxvirus, Chytridoipsis typographi, Nosema typographi, Gregarina typographi and Malamoeba scolyti could be observed in varying frequency depending on locality and year. The most dominant species was Ch. typographi , whereas N. typographi and M. scolyti could be found only in some few specimens.
