Unlike woodland edges, flower strips do not act as a refuge for cabbage stem flea beetle aestivation.

Background: Semi-natural habitats are generally considered to be beneficial to natural enemies of crop pests and pollinators. However, they could also be used by pests, such as the Cabbage Stem Flea Beetle (CSFB), Psylliodes chrysocephala, a major pest of winter oilseed rape, Brassica napus. Adults emerge from pupation in late spring and move to aestivation habitats.

The hump-shaped effect of plant functional diversity on the biological control of a multi-species pest community.

Plant taxonomic and functional diversity promotes interactions at higher trophic levels, but the contribution of functional diversity effects to multitrophic interactions and ecosystem functioning remains unclear. We investigated this relationship in a factorial field experiment comparing the effect of contrasting plant communities on parasitism rates in five herbivore species. We used a mechanistic trait-matching approach between plant and parasitoids to determine the amount of nectar available and accessible to parasitoids.

Prefabricated fibula free flap with dental implants for mandibular reconstruction.

Free fibula transplant is routinely used for mandibular reconstruction in head and neck cancer. Dental rehabilitation, the objective of mandibular reconstruction, requires the use of dental implants as supports for fixed or removable dentures. Positioning of fibular bone grafts and implants determines implant osseointegration and the possibilities of dental rehabilitation.

Velopharyngeal function after free thoracodorsal artery perforator flap in lateral and superior oropharyngeal cancer.

The purpose of this study was to report our experience with the free thoracodorsal artery perforator flap for reconstruction of the oropharynx and soft palate in head and neck cancer using a retrospective review of the medical charts of all patients undergoing oropharyngeal reconstruction by free thoracodorsal artery perforator flap during the same procedure as cancer resection between January 2011 and April 2013. Evaluation of speech, feeding and the presence of nasal emissions was performed 6 months after treatment in accordance with the Declaration of Helsinki. Nine patients were evaluated.
