Hygroreception in olfactometer studies

Physiological Entomology, 2009
Abstract In olfactometric studies, a technique used to measure insect behavioural bias towards airborne chemicals, many of the factors that could affect the bioassay outcome other than the volatiles themselves are carefully controlled (e.g.

Early results of an objective olfactometer

Journal of Medical Engineering & Technology, 1998
Although many people comment on their ability or inability to smell an odour, the accurate measurement of olfaction remains an elusive goal. Currently, there are no instruments available to objectively measure olfaction. This article outlines the design and early test results of a low cost, computer-based olfactometer which uses the frequency content ...

An Insect Olfactometer

The Canadian Entomologist, 1966
AbstractAn olfactometer is described in which an attractive zone is established and maintained in a precisely determined location on the floor (or wall) of an observation chamber and also in the air adjacent to it. Insects must therefore manifest their normal behavior in finding their way to it.

An Insect Olfactometer

Journal of Economic Entomology, 1926
Briefly stated, the insect olfactometer consists of a specially constructed Y-tube through which insects pass from a dark chamber, being attracted by a light suspended near the free ends of the forks of this tube. The dark chamber is attached to the base of the Y-tube, while a suction apparatus to draw odors through the forks is attached at the point ...

Economical and Disposable Olfactometer

Annals of the Entomological Society of America, 1968
In assaying the attractant quality of the aroma produced by the male large milkweed bug, Oncopeltus fasciatus (Dallas), on the female of the species (Lener 1967) I tried various types of olfactometers, but for 1 reason or another none seemed satisfactory. Some were too difficult for me to construct with my limited resources.

A long-duration ring test of olfactometers

1992
Abstract An air quality standard for odours is used in the Netherlands for a number of years and olfactometry plays a central role in it. The large variation in results of olfactometric measurements is a big problem in practice. Therefore, a draft guideline for olfactometric measurements was issued in the Netherlands in 1990. In order to evaluate the

A Body Capacitor-Olfactometer for Squirrels and Rats

Journal of Mammalogy, 1969
The body capacitor-olfactometer described herein was developed for the purpose of measuring quantitatively the number and duration of odor seeking (primarily food seeking) responses of wild ground squirrels (Spermophilus spp.) and rats (Rattus spp.) to various olfactory cues presented free of the in- fluence of taste, without the reward of food, and ...

Olfactometer Experiments with Male Braconids

Annals of the Entomological Society of America, 1950
The parasitic wasp, Microbracon hebetor (Say) is well known in biological control as a very useful enemy of lepidopterous pests in stored grains. The wasp is also well known for its usefulness in genetic investigation as evidenced by the fact that Dr. P. W. Whiting and associates have published genetic studies on the organism (as Habrobracon juglandis (

Olfactory Stimulus Control Evaluated in a Small Animal Olfactometer

Perceptual and Motor Skills, 1974
A fully automated air-stream olfactometer and test chamber are described. Studies with rats using a discrete trials, go, no-go training procedure demonstrate that olfactory discriminations are acquired rapidly and, under appropriate conditions, with few or no errors.

Olfactometers According to EN 13725

2017
In 1995 the technical committee TC264 air quality of the European Committee for Standardization convened the working group 2, which developed an odor testing standard. It was released in 2003 as EN 13725 air quality – measurement of odor concentration using dynamic olfactometry.
