Myrosinase: gene family evolution and herbivore defense in Brassicaceae
The evolution of the glucosinolate-myrosinase system and its impact on the interaction between plants and insects are discussed, and data suggesting additional functions in the defense against pathogens and in sulfur metabolism are reviewed. Expand
Landscape heterogeneity and farming practice influence biological control
Impact of natural enemies on the population development on the bird cherry-oat aphid on conventional and organic farms was measured by pairing farms with similar landscape features but different farming systems, and impact was greater in landscapes where arable land was contiguous. Expand
The influence of grazing intensity and landscape composition on the diversity and abundance of flower‐visiting insects
The results suggest that planning for conservation of biodiversity at landscape scales may be better than implementing grazing guidelines for individual grasslands, and that grazing intensity should vary within or between landscapes to preserve pollinator diversity. Expand
Pollen beetle (Meligethes aeneus) oviposition and feeding preference on different host plant species
There was good agreement in plant species ranking as oviposition hosts between the field, semi‐field and greenhouse trials and Pollen beetles seem to have a wider host range for feeding than for Oviposition. Expand
Complex Formation of Myrosinase Isoenzymes in Oilseed Rape Seeds Are Dependent on the Presence of Myrosinase-Binding Proteins1
Using size-exclusion chromatography, it is shown that myrosinases with subunit molecular masses of 62 to 70 kD were present as free dimers from the antisense seed extract, whereas in the wild type, they formed complexes, indicating that MBPs are necessary for myrosInase complex formation of the 62- to 70-kD myrosINases.

Yield increase attributable to aphid predation by ground-living polyphagous natural enemies in spring barley in Sweden
The study shows that yield increases attributable to predators can be compared with yield increases from insecticide use for the evaluation of different management strategies. Expand
Diet, fecundity and egg size in some polyphagous predatory carabid beetles
Variations in fecundity, as well as the ability of the medium‐sized species to also build up fat reserves, were obtained when beetles were subjected to different dietary regimes consisting of aphids, or foods with a lower or higher protein content. Expand
By manipulating landscape structure and composition, improvement in the condition of polyphagous predatory carabid beetles could be achieved, thereby potentially increasing populations of these beneficial insects. Expand
Stand specific occurrence of coarse woody debris in a managed boreal forest landscape in central Sweden
Abstract Forests long subjected to management for timber production contain only a fraction of the volumes of coarse woody debris (CWD) found in pristine forests. This is a threat to many organismsExpand
Variation in trichome density and resistance against a specialist insect herbivore in natural populations of Arabidopsis thaliana
The hypotheses that resistance to a specialist herbivore, the diamondback moth, Plutella xylostella (L.) (l.) (Lepidoptera: Plutellidae), is positively related to the density of leaf trichomes, and that oviposition preference by female moths is positively correlated to larval performance on different populations and maternal lines of the host plant were examined.
