Within this project we assess whether wildflower strips and companion plants increase the control of cabbage pests Plutella xylostella L. (Lepidoptera: Plutellidae), Mamestra brassicae L. (Lepidoptera: Noctuidae) and Pieris rapae L. (Lepidoptera: Pieridae) by (1) naturally occurring parasitoids and predators and (2) mass‐releasedn Trichogramma brassciae (Bezdenko) (Hymenoptera: Trichogrammatidae) parasitoids. Two organic cabbage fields were used for this study: adjacent to each field a wildflower strip was sown and companion plants (Centaurea cyanus L. (Asteraceae)) intermixed within the crop. Within each field ~15,000 M. brassicae eggs were placed out to determine the parasitism rates by mass‐released T. brassicae and to assess the levels of egg... |

The species Agonum nigrum DEJEAN, 1828, rare in central Europe, is reported for the first time from Switzerland. A distribution map is provided, based on reviewed specimens from museum collections and on literature data. Agonum nigrum is a Mediterranean species with a core distribution in southern Europe. The Swiss locality is situated on the upper Rhine near Basel in an area of meadows and light forest, which has been strongly shaped by man. The habitat is characterized by regular artificial inundation for ground water supply. The characters distinguishing A. nigrum from the similar Agomun atratum (DUFTSCHMID, 1812) are critically examined, and corrected or supplemented when neccssary. |

Beneficials can prevent or reduce outbreaks of pest species. To strengthen the populations of beneficials, their food sources must be improved in cultivated areas. The effects of habitat management for augmenting beneficial population on parasitism and predation rates of three lepidopteran pest species were investigated on two organic fields in Alten (Switzerland). The aim was to improve pest regulation through wild flower strips along fields and by planting Centaurea cyanus as companion plant within the crop. Strips of Centaurea cyanus and Fagopyrum esculentum increased parasitsm on the lepidopteran pests. C. cyanus planted as companion plant furthermore increased predation on the eggs and parasitism of the larvae of Mamestra brassicae. Several... |

Flowery field margins and intersowing of crops with flowers are used as management practices to promote arthropod biodiversity as well as biocontrol agents. Positive effects of enhancement (in abundance and species richness) of hymenopteran parasitoids on control of Lepidoptera pests have previously been demonstrated. However, effects on predatory arthropods, which may also serve as pest control agents, remain unclear. In an experimental study in cabbage fields we tested how sown flower strips on field margins and intersowing with cornflower affected the species richness, abundance and community composition of ground beetles and spiders. Furthermore, we investigated whether effects of flower margins are dependent on the distance from the field margins. We... |

Leistus fulvibarbis Dejean, 1826, wurde zum ersten Mal seit mehr als 100 Jahren wieder für die Schweiz nachgewiesen. Anhand dieses Wiederfunds in Basel soll auf die Fundumstände eingegangen werden und die Verbreitung und mögliche Ausbreitungswege dieser Art diskutiert werden. L. fulvibarbis kommt von Westeuropa über den Mittelmeerraum bis nach Kleinasien vor (Horion, 1941; Turin, 1981) und wird bei Jeannel(1947) als typische Art für ein atlantisches Verbreitungsmuster vorgestellt. In Frankreich ist die Art verbreitet, fehlt aber im Nordosten (Jura und Vogesen) (Deville, 1921; Jeannel, 1941). Im Elsass ist sie bei Callot& Schott (1993) nicht in der Faunenliste erwähnt, sondern nur als alte Meldungen ohne Belege von Bourgeois (ca. 1910) und Scherdlin... |

Within the context of the project «Pilot Study for a Red List of Staphylinids of Switzerland (Coleoptera, Staphylinidae)» of the Swiss Federal Office for the Environment (BAFU), the checklist of rove beetles (excluding the subfamily Pselaphinae) in Switzerland is compiled. It accounts for all species that 1) have a record in the database of the Centre Suisse de Cartographie de la Faune, 2) are listed in the unpublished species list compiled by C. Besuchet, and 3) are listed for Switzerland in the catalogue by Löbl & Smetana (2004). In all, 1421 staphylinid taxa (1414 species and 7 additional subspecies) (excl. Pselaphinae) have been recorded from Switzerland, among them 1297 monotypical species, 110 polytypical species represented by only one... |

This work, which is part of a project called Biocomes (www.biocomes.eu), is financially supported by the European Union and it focuses on the control of the cabbage moth Mamestra brassicae (Linnaeus, 1758) (Lepidoptera: Noctuidae) through mass release of the egg parasitoid Telenomus sp. (Hymenoptera: Scelionidae). |

Die Laufkäfer und Sandlaufkäfer (Coleoptera, Carabidae) sind ausgezeichnete ökologische Zeigerorganismen auch für naturschutzrelevante Untersuchungen, sofern je nach Fragestellung die entsprechenden autökologischen oder taxonomischen Parameter bekannt sind. Die für die Schweizer Carabiden verfügbaren Angaben sind oft wenig differenziert und beruhen meist auf der qualitativen Interpretation zufällig verfügbarer Angaben. Die vorliegende Publikation stützt sich vornehmlich auf eine quantitative Auswertung umfangreicher, räumlich repräsentativer Primärdaten. Die hier gewählte Form einer kommentierten Liste bietet sich für verschiedenste Forschungsbereiche wie Bioindikation, Faunistik oder Biogeographie als einfach zu benutzendes, dabei aber aussagekräftiges... |
