Abstract:
... The pine weevil (Hylobius abietis L.) is among the worst pests of newly planted conifer seedlings in Europe. EU regulations restrict the use of insecticides, the cost of mechanical site preparation (MSP) is high, and it has even been suggested that MSP should be abandoned due to social and environmental causes. The aim of this study was to investigate i) the field performance of Norway spruce (Pic ...

Abstract:
... Adult feeding preferences of Hylobius abietis on Picea abies, Larix decidua, Pinus sylvestris, Pseudotsuga menziesii, Abies alba and Betula pendula were tested in outdoor conditions. The preferred food source was P. menziesii, and the mean bark area consumed per seedling was 440.8 ± 147.9 mm². The second most preferred host was P. abies. The coniferous species that suffered the least damage was A. ...

Abstract:
... Nursery-grown Norway spruce Picea abies seedlings are often heavily attacked by the pine weevil Hylobius abietis on clear-cuts the first years after planting. Because the seedlings are not resource-limited during the growing phase in the nursery they are expected to invest less in defence than naturally regenerated seedlings already present on the clear-cuts. The latter have had to cope with vario ...

A side-effect of MeJA application is temporarily reduced height growth. This has generally been considered as nega ...

Abstract:
... Establishment of Norway spruce (Picea abies (L.) Karst.) seedlings is often restricted by competition from vegetation, drought, and damage by pine weevils. In this study, effects of mulching on these factors were investigated. Norway spruce seedlings were planted on fresh and 1-year-old clearcuts treated with mulch on three sites in southern Sweden. Mulch was made of slash from the old stand and a ...

The distribution of genetic variation within and among 20 European sites infested by the large pine weevil, Hylobius abietis, was analysed using dominant amplified fragment length polymorphism markers. Analysis of molecular variance was performed at the European, regional and local scales. Most of the genetic variability was found within rather than among populations and the global fixation index ...

(Coleoptera: Curculionidae). Our hypothesis was that we could find new, less volatile alkanoic acids or related compounds suitable for field application and with improved long-term duration. Alkanoic acids of varying chain ...

In assessments of pine weevil (Hylobius abietis (L.)) feeding on conifer seedlings in Sweden, positive linear relationships were found between the numbers of attacked seedlings and each of the numbers of seedlings killed by pine weevil feeding, the damage score, and the mean estimated extent of feeding on damaged seedlings. Hence the damage score was described by polynomial regression on number of ...
