What factors influence the diversity of saproxylic beetles? A multiscaled study from a spruce forest in southern Norway
The diversity in different groups of obligate saproxylic beetles was related to ecological variables at three levels of spatial scale in mature spruce-dominated forest and factors connected to decaying wood and wood-inhabiting fungi were clearly the most important factors at all scale levels.
A host monoterpene influences Ips typographus (Coleoptera: Curculionidae, Scolytinae) responses to its aggregation pheromone
1 Host tree terpenes can influence attraction of conifer‐infesting bark beetles to their aggregation pheromones, and both synergistic and inhibitory effects have been reported.
Geochemistry of Pleistocene ash zones in cores from the North Atlantic
North Atlantic ash zones I (10 .6 ka BP), Il (57 .5 ka BP) and Ill (340 ka BP) were studied using single grain geochemical analysis (microprobe). The zones were defined only on the occurrence of
Kairomone response inThanasimus predators to pheromone components ofIps typographus
Methylbutenol alone, the specific pheromone component of Ips typographus, elicited no response, but synergestic effects appeared when methyl butenol was combined withcis-verbenol and ipsdienol.
Two sibling species of Leiopus Audinet-Serville, 1835 (Coleoptera: Cerambycidae) from Europe: L. nebulosus (Linnaeus, 1758) and L. linnei sp. nov.
The male genitalia characters, as well as spermathecae in females, were examined and found to provide strong support for this separation of the common European cerambycid Leiopus nebulosus into two sibling species.
A reservoir model for the main Pliocene reservoirs of the Bahar Field in the Caspian Sea, Azerbaijan
In this paper the results of a reservoir evaluation study of the Bahar Field, one of the most important oil and gas fields in the Azerbaijanian sector of the Caspian Sea are presented. The study has
Revision of the subgenus Lasiodites Jelínek, 1999, stat. nov. of the genus Phenolia Erichson, 1843 from Africa and Madagascar (Coleoptera, Nitidulidae)
This revision covers the species of the subgenus Lasiodites Jelinek, 1999, stat. nov. of the genus Phenolia Erichson, 1843, distributed in Africa, Madagascar and surrounding islands. An
Pathogenicity of the nematodes Bursaphelenchus xylophilus and B. mucronatus to Pinus sylvestris seedlings: A greenhouse test
Pathogenicity tests using 3‐year‐old seedlings of Pinus sylvestris grown in the greenhouse and inoculated with 10 000 nematodes demonstrated that an isolate of Bursaphelenchus xylophilus induced pine wilt in nine of the twenty seedlings used for each isolate.
