Field evaluation of entomopathogenic nematodes against orchard pests Organic Eprints
Kuske, Stefan; Daniel, Claudia; Sarraquigne, J.-P.; Jermini, M.; Conedera, M.; Peters, A.; Grunder, J. M..
Survival of pest in micro-plot trials (container studies) or field plot trials was monitored after exposure to commercially used EPN strains. Experimental plots were artificially infested with pest larvae that naturally burrowed into the soil for diapause. Either larval mortality or adult emergence, was assessed to estimate the control effect of the EPN treatment. Here we present preliminary results from three ongoing projects.

Kirschenfliege: Wie sie ihre Feinde austrickst Organic Eprints
Kuske, Stefan; Grunder, Jörg; Daniel, Claudia; Wyss, Eric.
Seit Jahrzehnten wird intensiv nach alternativen Kontrollmassnahmen zur chemischen Bekämpfung der Kirschenfliege gesucht (Boller und Remund 1980). Bis heute leider nur mit bescheidenem Erfolg für die Praxis. Der Einsatz insektenparasitischer Nematoden zur vorbeugenden Bekämpfung der im Boden überwinternden Schädlinge hat jüngst aber neue Hoffnungen geweckt. Wieso sich diese sonst so zuverlässigen Nützlinge an der Kirschenfliege ebenfalls die Zähne ausbeissen, soll im vorliegenden Artikel aufgezeigt werden.

Potenzial entomopathogener Pilze zur Kontrolle des Rapsglanzkäfers Organic Eprints
Kuske, Stefan; Pilz, Christina; Kölliker, Ursula.
Fungal isolates of Beauveria bassiana (21 isolates), B. brongniartii (2), Paecilomyces fumosoroseus (1) and Metarhizium anisopliae (1) were screened for virulence against pollen beetle Meligethes aeneus. Most of the tested B. bassiana isolates originated from naturally infected pollen beetles collected in Switzerland. In a lab bioassay adult beetles were dipped into a defined conidial suspension and fungal infection was recorded after 15 days. Seven isolates of B. bassiana as well as the P. fumosoroseus F4K caused infection rates between 67.9% and 80% respectively and proved to be promising strains for potential use against pollen beetles. However, more experiments are needed to confirm their biological control potential under field conditions.
