Statistical Inference for Olfactometer Data

Journal of the Royal Statistical Society Series C: Applied Statistics, 2007
SummaryOlfactometer experiments are used to determine the effect of odours on the behaviour of organisms such as insects or nematodes, and typically result in data comprising many groups of small overdispersed counts. We develop a non-homogeneous Markov chain model for data from olfactometer experiments with parasitoid wasps and discuss a relation with

An olfactometer for small rodents [PDF]

Behavior Research Methods, Instruments, & Computers, 1984
An olfactometer that captures and delivers biological odors at experimenter-controlled times, without dilution, is described. The apparatus is quiet, efficient, versatile, animal-safe, and fairly inexpensive. Tests indicate that the device is successful in isolating transitory odors.

Recovery of Odorants from an Olfactometer Measured by Proton-Transfer-Reaction Mass Spectrometry

Italian National Conference on Sensors, 2013
The aim of the present study was to examine the recovery of odorants during the dilution in an olfactometer designed according to the European standard for dynamic olfactometry.

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, EarlyView.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Tritrophic interactions between cereals, aphids and parasitoids: Discrimination of different plant-host complexes by Aphidius rhopalosiphi (Hymenoptera: Aphidiidae)

European Journal of Entomology, 2000
The tritrophic interactions between two different plant-host complexes, Avena sativa-Sitobion avenae, Triticum aestivum-S. avenae and the aphid parasitoid Aphidius rhopalosiphi were studied with respect to odour learning and recognition by the parasitoid.

How useful are olfactometer experiments in chemical ecology research?

Communicative & Integrative Biology, 2013
Olfactometer experiments, in which arthropods are given the choice between two or more odor sources to test behavioral preferences, are commonly used in chemical ecology research.

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

Medical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Preliminary Analysis of Several Attractants and Spatial Repellents for the Mosquito, Aedes albopictus using an Olfactometer

Journal of Insect Science, 2012
Mosquito attractants and spatial repellents hold great promise in controlling mosquito pests. In assessing the effectiveness of mosquito attractants and repellents, a good olfactometer system, and optimized testing conditions, are essential.

Loss‐of‐Function Mutation in CER2‐LIKE1 Reduced Accumulation of Cuticular Wax and Susceptibility to Thrips in Welsh Onion

Plant Biotechnology Journal, EarlyView.
ABSTRACT Cuticular waxes can form a hydrophobic barrier on aerial plant surfaces, which is essential for mediating plant‐environment interactions by providing protection against both biotic and abiotic stresses. In this study, a cuticular wax mutant (gl) was identified and characterised in Welsh onion (Allium fistulosum L.), exhibiting a functional ...
