Time of oviposition and its influence on the development of Hylobius abietis (L.) (Col., Curculionidae)
Autor: B. Lekander, E. Kangas, H. H. Eidmann, B. Bejer
Publikováno v: Zeitschrift für Angewandte Entomologie. 100:417-421
In experiments with breeding billets in Denmark, Sweden, and Finland, oviposition of the pine weevil Hylobius abietis L. started during May-June and ended in August. Most eggs were laid during June and July. Pine weevils originating from eggs laid ea

Silviculture and insect problems1
Autor: H. H. Eidmann
Publikováno v: Zeitschrift für Angewandte Entomologie. 99:105-112
Changes in structure or community composition within forest ecosystems and their patterns in time and space affect insect populations. Silvicultural measures may cause temporary disturbances or have long-term influences on the ecosystems. They may de

Assessment of pine weevil numbers on clear-cut and forest sites with shelter boards and pitfall traps
Autor: H. H. Eidmann
Publikováno v: Anzeiger für Schädlingskunde Pflanzenschutz Umweltschutz. 70:68-72
Field experiments were conducted in 1991 and 1992 on clear-cut and forest sites in four forest areas in southern Sweden with the aim to test possibilities for estimating pine weevil (Coleoptera: Curculionidae) population sizes. More pine weevils (Hyl

Impact of bark beetles on forests and forestry in Sweden
Autor: H. H. Eidmann
Publikováno v: Journal of Applied Entomology. 114:193-200
The impacts of bark beetles in Sweden and the role and management of bark beetle breeding substrate are discussed. Of the six important species damaging living trees, Tomicus piniperda and Ips typographus have the greatest impact. The damage caused b

Response of the pine weevilHylobius abietisL. (Col., Curculionidae) to host volatiles in different phases of its adult life cycle
Autor: H. Nordenhem, H. H. Eidmann
Publikováno v: Journal of Applied Entomology. 112:353-358
The response of adult Hylobius abietis L. before and after the spring flight period and in autumn to host volatiles was studied in field experiments using pitfall traps and trapping billets. In spring and early summer, pitfall traps baited with α-pi

Host recognition and aggregation behaviour ofHylastes cuniculariusErichson (Col., Scolytidae) in the laboratory
Autor: Å. Lindelöw, E. Kula, H. H. Eidmann
Publikováno v: Journal of Applied Entomology. 112:11-18
Host recognition and aggregation behaviour in the black spruce beetle, Hylastes cunicularius Erichson, were studied in choice experiments in the laboratory. The beetles tended to aggregate. Aggregation occurred at host material or at beetles and was
