Fungal symbionts of siricid woodwasps: isolation techniques and identification
Autor: Iben Margrete Thomsen, S. Harding
Publikováno v: Forest Pathology. 41:325-333
Summary European woodwasps of the genera Sirex and Urocerus have symbiotic relationships with basidiomycetes, Amylostereum chailletii (Pers. : Fr.) Boid. and Amylostereum areolatum (Fr.) Boid. The fungal symbionts of siricid woodwasps are contained i

Clonality and genetic variation in Amylostereum areolatum and A. chailletii from northern Europe
Autor: Iben Margrete Thomsen, Jan Stenlid, Rimvydas Vasiliauskas
Publikováno v: New Phytologist. 139:751-758
Genetic variation within and between vegetative compatibility groups (VCGs) of Amylostereum areolatum (Fr.) Boid. and Amylostereum chailletii (Pers.: Fr.) Boid. isolates was investigated. DNA fingerprints were made using the M13 core sequence as a pr

Species composition and flight periods of horntail wasps (Hymenoptera: Siricidae) within Basque Country pine forests, with the confirmation of establishment of the exotic species Urocerus albicornis
Autor: A. Goldarazena
Publikováno v: Graellsia. 71:e020
Species composition and flight periods of horntails wasps in Basque Country pine forests in northern Spain are studied in order to determine if alien invasive species have been introduced and established. Panel traps baited with Contech Inc. Sirex no

Dieback and death of larch caused by Ceratocystis laricicola sp. nov. following attack by Ips cembrae
Autor: H. Steele, D. B. Redfern, J. T. Stoakley, D. W. Minter
Publikováno v: Plant Pathology. 36:467-480
Circumstantial and experimental evidence suggests that the bark beetle Ips cembrae acts as a vector for Ceratocystis laricicola sp. nov. which it introduces into larches during breeding attacks. The fungus kills bark and cambium, and invades the sapw

The oviposition biology of siricid woodwasps in Europe
Autor: J. P. Spradbery
Publikováno v: Ecological Entomology. 2:225-230
1. The oviposition biology of the siricid woodwasps, Sirex noctilio, S.juvencus, S.cyaneus, Urocerus gigas, U.augur, U.fantoma, U.sah and Xeris spectrum was investigated. The fecundity of each siricid species was related to adult size although S.noct
