A Wind Tunnel for Odor Mediated Insect Behavioural Assays
Knudsen, Geir; Tasin, Marco; Aak, Anders; Thöming, Gunda (Journal article; Peer reviewed, 2018-11-11)Olfaction is the most important sensory mechanism by which many insects interact with their environment and a wind tunnel is an excellent tool to study insect chemical ecology. Insects can locate point sources in a ... -
Adjusting the scent ratio: using genetically modified Vitis vinifera plants to manipulate European grapevine moth behaviour
Salvagnin, Umberto; Malnoy, Mickael; Thöming, Gunda; Tasin, Marco; Carlin, Silvia; Martens, Stefan; Vrhovsek, Urska; Angeli, Sergio; Anfora, Gianfranco (Journal article; Peer reviewed, 2017-06-02)Herbivorous insects use olfactory cues to locate their host plant within a complex olfactory landscape. One such example is the European grapevine moth Lobesia botrana, a key pest of the grape in the Palearctic region, ... -
Attraction of Chrysotropia ciliata (Neuroptera, Chrysopidae) Males to P-Anisaldehyde, a Compound with Presumed Pheromone Function
Thöming, Gunda; Koczor, Sándor; Szentkirályi, Ferenc; Norli, Hans Ragnar; Tasin, Marco; Knudsen, Geir (Peer reviewed; Journal article, 2020-06-26)In a field-trapping experiment with plant volatiles, we observed notably high attraction of green lacewing (Chrysotropia ciliata) males to the compound p-anisaldehyde. Based on this finding, we initiated the present study ... -
Etablering av våroljevekster
Abrahamsen, Unni; Waalen, Wendy; Strand, Einar; Henriksen, Trond Maukon; Brodal, Guro; Thöming, Gunda (Journal article, 2018-02)En rekke forhold har betydning for en vellykket etablering av oljevekster; jordart, jordarbeiding, frøkvalitet, sådybde, såmengde, tilgang til næring, temperatur og nedbør etter såing og angrep av skadedyr. -
Fra grasmark til kjølmark - i potet
Schjøll, Annette; Johansen, Tor Jacob; Thöming, Gunda; Møllerhagen, Per (NIBIO Bok;7(1)2021, Chapter, 2021) -
Kairomone-assisted trap cropping for protecting spring oilseed rape (Brassica napus) from pollen beetles (Coleoptera: Nitidulidae)
Thöming, Gunda; Solhaug, Knut Asbjørn; Norli, Hans Ragnar (Peer reviewed; Journal article, 2020-04-30)BACKGROUND Pollen beetles are key pests in oilseed rape (OSR) production. These beetles use visual and olfactory cues to locate their host plants at specific phenological stages, hence trap cropping may represent an ... -
The Potential for Decision Support Tools to Improve the Management of Root-Feeding Fly Pests of Vegetables in Western Europe
Collier, Rosemary; Mazzi, Dominique; Schjøll, Annette; Schorpp, Quentin; Thöming, Gunda; Johansen, Tor Jacob; Meadow, Richard; Meyling, Nicolai Vitt; Cortesero, Anne-Marie; Vogler, Ute; Gaffney, Michael T.; Hommes, Martin (Peer reviewed; Journal article, 2020-06-13)Several important vegetable crops grown outdoors in temperate climates in Europe can be damaged by the root-feeding larvae of Diptera (Delia radicum, Delia floralis, Chamaepsila rosae, Delia platura, Delia florilega, Delia ... -
Recruiting on the Spot: A Biodegradable Formulation for Lacewings to Trigger Biological Control of Aphids
Pålsson, Joakim; Thöming, Gunda; Silva, Rodrigo; Porcel, Mario; Dekker, Teun; Tasin, Marco (Journal article; Peer reviewed, 2019-01-05)Upon herbivory, plants release herbivore-induced plant volatiles (HIPVs), which induce chemical defenses in the plant as well as recruit natural enemies. However, whether synthetic HIPVs can be employed to enhance biological ... -
Root-associated entomopathogenic fungi manipulate host plants to attract herbivorous insects
Cotes, Belén; Thöming, Gunda; Amaya‑Gómez, Carol V.; Novák, Ondřej; Nansen, Christian (Peer reviewed; Journal article, 2020-12-30)Root-associated entomopathogenic fungi (R-AEF) indirectly infuence herbivorous insect performance. However, host plant-R-AEF interactions and R-AEF as biological control agents have been studied independently and without ... -
Semiochemicals and habitat manipulation to support green lacewing activity to reduce aphid infestations in agroecosystems
Thöming, Gunda; Knudsen, Geir (Peer reviewed; Journal article, 2021-03)Conservation biological control (CBC) is a promising tool for ecological intensification that aims to establish resilient natural enemy populations that contribute to pest management with reduced use of pesticides and at ... -
