Pathogens of Ips amitinus: new species and comparison with Ips typographus
Original language description
Ips amitinus and I.typographus are two serious pests of spruce in Europe, have similar bionomics and are likely to occur and meet on the same host trees. We therefore hypothesized that the two species support similar levels of similar pathogens. To testthis hypothesis, we collected mature beetles from three trap trees at each of eight study sites and determined beetle numbers and pathogen infection levels. In total, 938 mature I.amitinus beetles and 3435 of I.typographus were dissected; five pathogens,as well as intestinal nematodes and endoparasitoids, were detected. The neogregarine Mattesia schwenkei is reported here for the first time as a new pathogen in 9.4% of I.amitinus individuals at one site. Average infection levels of most pathogens (Chytridiopsis typographi, Gregarina typographi, Mattesia schwenkei and parasitoids) were significantly higher in I.typographus than in I.amitinus. Metschnikowia typographi was confirmed only in Ips amitinus, while the microsporidium of Nosema
