Comparison of odor detection thresholds for n-butanol and benzaldehyde determined with a dynamic dilution olfactometer and in room air

Indoor Environments
The German Committee on Indoor Air Guide Values (AIR) has developed a concept of odor guide values (OGV) based on odor detection thresholds (ODT) to assess the plausibility of complaints about odor annoyance. ODT were determined directly at the nose with

Anopheles darlingi (Diptera: Culicidae) displays increased attractiveness to infected individuals with Plasmodium vivax gametocytes

Parasites & Vectors, 2014
Background Most hematophagous insects use host odours as chemical cues. The odour components, some physiological parameters and host attractiveness are affected by several conditions, including infection by parasites, e.g., plasmodia and, therefore ...
