Larssoniella duplicati n.sp . (Microsporidia, Unikaryonidae), a newly described pathogen infecting the double-spined spruce bark beetle, Ips duplicatus (Coleoptera, Scolytidae) in the Czech Republic

Original language description

Larssoniella duplicati n.sp. infects the midgut muscularis, the Malpighian tubules, and the ovaries of adult Ips duplicatus (Sahlb.) in the Czech Republic. The microsporidian attacks up to 50% of the population. Oval spores of two sizes, 3?3.5x1.5?2 and2?2.5x1.5 ?m have the polar filament coiled in 6/7 coils, representing primary and environmental spores, respectively. In early sporogony the young spores produce long electron dense threads and tubules of secretions, which remain fixed around the sporeand avoid their free release during dissection of infected hosts. The microsporidian was not found in associated bark beetles such as Ips typographus (L.), or I. amitinus (Eichh.) and others.

Czech description

Larssoniella duplicati n.sp. napadá svalovinu střeva, MAlpigické trubice a ovária dospělců. Mikrosporode napadá až 50%. během časné sporogonie mladé spory produkují dlouhé electron dense sekrece, které zůstávají na povrchu. Mikrosporide nebyla nalezena vdalších broucích jako Ips typographus (L.), I. amitinus (Eichh.) a dalších.
