Fungi associated with the fir bark beetle Cryphalus piceae in Poland

Abstract

The aim of this study was to identify fungi associated with Cryphalus piceae on European silver fir (Abies alba) in Poland and to test the pathogenicity of selected isolates. Fungi were isolated from five populations of overwintered adults and their galleries. A great diversity of taxa was associated with C. piceae. In total, 2487 isolates, including 58 species distributed in 25 genera, were obtained. The two most frequently isolated fungi, an undescribed species of the genus Geosmithia and Ophiostoma piceae, appeared to be specifically associated with C. piceae, whereas Pesotum fragrans, Pesotum sp. and Sporothrix sp. were sporadically associated. Two-year-old seedlings of silver fir were woundinoculated with three species of fungi (Geosmithia sp., O. piceae and Pesotum sp.) recovered from C. piceae. Only Pesotum sp. showed pathogenic ability, but we do not consider it to be an important pathogen of A. alba.

Isolation and identification of Sydowia polyspora and its pathogenicity on Pinus yunnanensis in Southwestern China

“…In this study, S. polyspora has been isolated from the bark beetles and galleries of T. yunnanensis , which showed that S. polyspora could associate to T. yunnanensis in its lifecycle stage. This finding appears to supplement previous research (Jankowiak & Kolařík, ; Jankowiak & Rossa, ; Jankowiak et al., ). Our finding also indicates that S. polyspora has an association with bark beetles but not specifically with the species.…”

“…It has also been reported from a variety of conifers as the hosts of (Smerlis, 1970;Talgø et al, 2010). The present study demonstrates that S. polyspora is able to colonize and utilize P. (Jankowiak & Kolařík, 2010;Jankowiak & Rossa, 2008;Jankowiak, Rossa, & Mista, 2007). In this study, S. polyspora has been isolated from the bark beetles and galleries of T. yunnanensis, which showed that S. polyspora could associate to T. yunnanensis in its lifecycle stage.…”

“…Several studies have reported that H. dematioides could be introduced into host trees by Tomicus species such as T. piniperda and T. minor , as well as other bark beetle species, such as Ips cembrae (Heer), Pityogenes bidentatus (Herbst) and Crypbalus piceae (Ratz.) (Jankowiak & Kolařík, ; Jankowiak & Rossa, ; Jankowiak, Rossa, & Mista, ). In this study, S. polyspora has been isolated from the bark beetles and galleries of T. yunnanensis , which showed that S. polyspora could associate to T. yunnanensis in its lifecycle stage.…”

Distribution, Host Records, and Symbiotic Fungi ofEuwallacea fornicatus(Coleoptera: Curculionidae: Scolytinae) in China

“…Three representative ITS rDNA sequences (Hulcr12051 and LL84) were 100% identical to the hypocrealean fungus Sarocladium strictum and an uncultured Acremonium (GenBank accessions KM249080 and HG936339, respectively). Sarocladium has previously been reported to be associated with bark and ambrosia beetles throughout the northern temperate region (Hutchison 1999;Jankowiak et al 2007;Jankowiak & Kolařík 2010), as well as from mites Steneotarsonemus spinki Smiley (Acari: Tarsonemidae) in Taiwan (Hsieh et al 1980). Acremonium sp.…”
