Pathogen's level and parasitism rate in Ips typographus at high population densities: importance of time
Original language description
We compared the levels of pathogen infection in parental beetles, parasitism of the offspring, abundance of predators and breeding performance success of univoltine populations of Ips typographus in plots characterized by short-term (2-3 years) outbreaks vs. those with long-term (more than 10 years) outbreaks on two localities at ca. 1100 m altitude in the Sumava Mts. The numbers of I.typographus were high in all plots, whether the plots were characterized by long-term outbreaks or short-term outbreaks. The numbers of maternal galleries in the sample areas ranged from 300 to 400 per m(2). The density of parental beetle galleries, abundance of surviving specimens of I.typographus, and length of maternal galleries did not differ between plots. The short-term outbreaks had only fewer ectoparasitoids of I.typographus and a lower percentage of parasitism and infection level of Mattesia schwenkei than the long-term outbreaks even though the maternal gallery densities and beetle production were the same.
