Journal ArticleDOI
A Conserved Dedicated Olfactory Circuit for Detecting Harmful Microbes in Drosophila
Marcus C. Stensmyr,Hany K.M. Dweck,Abu Farhan,Irene Ibba,Antonia Strutz,Latha Mukunda,Jeanine Linz,Veit Grabe,Kathrin Steck,Sofia Lavista-Llanos,Dieter Wicher,Silke Sachse,Markus Knaden,Paul G. Becher,Yoichi Seki,Bill S. Hansson +15 more
TL;DR: This work identifies a functionally segregated olfactory circuit in flies that is activated exclusively by geosmin, which constitutes an ecologically relevant stimulus that alerts flies to the presence of harmful microbes.
Journal ArticleDOI
Yeast, not fruit volatiles mediate Drosophila melanogaster attraction, oviposition and development
Paul G. Becher,Paul G. Becher,Gerhard Flick,Elżbieta Rozpędowska,Elżbieta Rozpędowska,Alexandra Schmidt,Arne Hagman,Sébastien Lebreton,Mattias C. Larsson,Bill S. Hansson,Jure Piškur,Peter Witzgall,Marie Bengtsson +12 more
TL;DR: It is shown that baker's yeast Saccharomyces cerevisiae on its own is sufficient for fruit fly attraction, oviposition and larval development, and the traditional plantherbivore niche concept needs to be updated, to accommodate for the role of micro-organisms in insectplant interactions.
Journal ArticleDOI
Flying the fly: long-range flight behavior of Drosophila melanogaster to attractive odors.
TL;DR: This wind tunnel assay based on a conspicuous and unambiguous behavioral response provides the necessary resolution for the investigation of physiologically and ecologically relevant odors and will become an essential tool for the functional analysis of the D. melanogaster olfactory system.
Journal ArticleDOI
Floral to green: mating switches moth olfactory coding and preference
Ahmed M. Saveer,Sophie H. Kromann,Göran Birgersson,Marie Bengtsson,Tobias U. T. Lindblom,Anna Balkenius,Bill S. Hansson,Peter Witzgall,Paul G. Becher,Rickard Ignell +9 more
TL;DR: It is shown for the first time, to the knowledge, that a noctuid moth switches its olfactory response from food to egg-laying cues following mating.
Journal ArticleDOI
Nostocarboline: isolation and synthesis of a new cholinesterase inhibitor from Nostoc 78-12A
TL;DR: Nostocarboline was found to be a potent butyrylcholinesterase (BChE) inhibitor, with an IC(50) of 13.2 microM, which is comparable to galanthamine, an approved drug for the treatment of Alzheimer's disease (AD).
