The Nasal Ranger is a state-of-the-art portable, field olfactometer for confidently measuring and quantifying odor strength in the ambient air. ...
Four different odours and odorants measurement methods were compared: field olfactometry using Nasal Ranger® field olfactometer, dynamic olfactometry according to PN-EN 13725:2007 standard, colorimetric assays (hydrogen sulphide, ammonia) and gas chromatography-mass spectrometry (GC-MS) methods (methanethiol, ethanethiol, dimethyl sulphide). ...

However, B. rapa was preferred over B. napus when both species were in the bud stage, indicating some inherent preferences for B. rapa. Responses of M. aeneus in olfactometer tests to the odours of B. napus and B. rapa at the bud and flowering growth stages, reflected those of the semi-field arena bioassay. ...
We tested the hypothesis that the prepupal C. pomonella parasitoid Mastrus ridibundus Gravenhorst (Hymenoptera: Ichneumonidae) exploits the larval aggregation pheromone to locate host prepupae. In laboratory olfactometer experiments, female M. ridibundus were attracted to 3-day-old cocoons containing C. pomonella larvae or prepupae. ...
