Virulence and horizontal transmission of Beauveria pseudobassiana S.A. Rehner & Humber in Ips sexdentatus and Ips typographus (Coleoptera: Curculionidae)

Our results indicate that B. pseudobassiana ARSEF 9271 is a promising microbial control agent against the tested Ips species and can horizontally spread among a population of both I. sexdentatus and I. typographus.
