Validating non-motivated methods and equipment for studying mouse olfactory behavior
… using existing liquid dilution behavioral olfactometers. We also aim to validate Triton-100x, a detergent, as a new anosmia inducing agent, as well as self-built, Do-it-yourself (DIY) behavioral olfactometers. Equipment and methods were tested using a variety of common-discrimination and …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
… stimuli of JB was evaluated with a Y-tube olfactometer. Beetles preferred the side of the Y-tube containing leaf tissue of apple or Virginia creeper over the side with no leaf. Beetles did not choose one plant species over the other. Bias test of beetle orientation in the Y-tube …

Factors affecting the response of thrips to an olfactory cue
… responses of thrips to an olfactory cue. Y-tube olfactometer assays testing MI under controlled conditions using populations collected from different countries showed that WFT differ in their response to an olfactory cue depending on which region of the world they are from. The work in this …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… natural enemy behavior was observed in a y-tube olfactometer to determine the role of odor cues from decaying mulch on habitat choice. In general, natural enemies were not attracted or repelled by mulch odors. Further work is needed before implementation of these habitat management strategies …

THE RESPIRATORY RESPONSE OF TRPV1 KNOCKOUT MICE TO TRIGEMINAL IRRITANTS
… Test.” In the present study, an air dilution olfactometer was used to administer volatile compounds to unanesthetized mice which were restrained in a double chamber plethysmograph. Respiration rate depression for female wild type (C57Bl/6J) mice was compared to female Trpv1 knockout mice for a …

Investigating host plant selection of harlequin bug, Murgantia histrionica (Hahn), in order to improve a trap cropping system for its management
… the duration of the ten week growing period. In olfactometer choice tests, male HB responded to plant volatiles of bean, collard and mustard, but preferred Brassica volatiles over those from bean. Female response to plant volatiles alone was weak and inconsistent. Both males and females preferred …

Learning and Olfactory Processing by the Parasitic Wasp, Cotesia Congregata, In Response to Concentration of Herbivore Related Tomato Volatiles
… 18-24 hours after conditioning in a Y-maze olfactometer. Wasps were conditioned in the presence of the complete volatile blend emitted by wounded tomato leaves (Solanum lycopersicum `Castlemart') and their attraction was assayed using controlled dose/emissions of cis-3-hexen-1-ol (green leaf …

Why Mosquitoes Bite Some People More Than Others: Metabolic Correlates of Human Attraction in AEDES AEGYPTI
… between subjects. We developed the uniport olfactometer as a method for discriminating subject attraction. Within our study population we distinguished three clusters of subjects who were differentially attractive to mosquitoes. We performed metabolic profiling with subject plasma samples …

The role of chemicals in the location of host plants by midge pests of UK fruit crops
… Bioassay work was carried out in a four-way olfactometer and a wind tunnel to assess female attraction to shoot material but no attraction was seen in either experiment. Solutions containing natural volatile extracts were obtained using entrainment onto Porapak resin. The effect of these …

La comunicazione chimica in Blattaria: contributo al miglioramento della lotta
… and interspecific level, using a "Y" tube olfactometer. Bioassays showed that faecal extracts obtained with methanol have a good intraspecific attractiveness and, in some cases, they showed also interspecific behavioral responses. A gel was prepared, having physical characteristics that …

The application of novel mass spectrometric techniques for the analysis of volatile organic compounds in different environments
… emission of bVOCs below ground. Using a Y-tube olfactometer it was shown that ozone at environmentally-realistic mixing ratios (ca. 100 ppbv) disrupts the ability of M. persicae to locate a host plant. Ozone was also shown to disrupt tritrophic signalling by inhibiting the location of prey by A. …

Host-Parasitoid Interactions of Two Invasive Drosophilids in Virginia Fruit Crops
1.) Sentinel traps were used to survey for parasitoids of frugivorous drosophilids in Virginia fruit cropping systems, and determine if parasitoids were attacking invasive flies Drosophila suzukii (Matsumura) and Zaprionus indianus Gupta (Diptera: Drosophilidae) in the field. Two parasitoids of …
