Nasonov pheromone of the honeybee - apis-mellifera-l (hymenoptera, apidae) .4. Comparative electroantennogram responses [PDF]

, 1982
Electroantennogram (EAG) responses from worker honeybee antennae were obtained for each Nasonov component. Response amplitudes to 10 μg of components correlated well with reported relative abilities to attract foragers in the field.

Mixtures of Two Bile Alcohol Sulfates Function as a Proximity Pheromone in Sea Lamprey. [PDF]

PLoS ONE, 2016
Unique mixtures of pheromone components are commonly identified in insects, and have been shown to increase attractiveness towards conspecifics when reconstructed at the natural ratio released by the signaler. In previous field studies of pheromones that

Competence without a Competence Pheromone in a Natural Isolate ofStreptococcus infantis [PDF]

Journal of Bacteriology, 2002
ABSTRACTMany streptococcal species belonging to the mitis and anginosus phylogenetic groups are known to be naturally competent for genetic transformation. Induction of the competent state in these bacteria is regulated by a quorum-sensing mechanism consisting of a secreted peptide pheromone encoded bycomCand a two-component regulatory system encoded ...

Aphid sex pheromone components: age-dependent release by females and species-specific male response [PDF]

, 1990
Sex pheromone released by Megoura viciae oviparae was collected and analysed for the quantity and re-lative amounts of each of the two biologically active compo-nents.

Sampling gravid Culex quinquefasciatus (Diptera: Culicidae) in Tanzania with traps baited with synthetic oviposition pheromone and grass infusions [PDF]

, 2000
The effectiveness of traps baited with (5R,6S)-6-acetoxy-5-hexadecanolide (the synthetic oviposition pheromone) and grass infusions in sampling a population of gravid Culex quinquefasciatus Say was conducted in Muheza, Northeast Tanzania.

Linking Genomic and Metabolomic Natural Variation Uncovers Nematode Pheromone Biosynthesis [PDF]

Cell Chemical Biology, 2018
In the nematodes Caenorhabditis elegans and Pristionchus pacificus, a modular library of small molecules control behavior, lifespan, and development. However, little is known about the final steps of their biosynthesis, in which diverse building blocks from primary metabolism are attached to glycosides of the dideoxysugar ascarylose, the ascarosides ...

Sex pheromone signal and stability covary with fitness

Royal Society Open Science, 2021
If sexual signals are costly, covariance between signal expression and fitness is expected. Signal–fitness covariance is important, because it can contribute to the maintenance of genetic variation in signals that are under natural or sexual selection ...

Environmentally vulnerable noble chafers exhibit unusual pheromone-mediated behaviour [PDF]

, 2018
Conserving populations of environmentally vulnerable insect species requires a greater understanding of the factors that determine their abundance and distribution, which requires detailed knowledge of their population and community ecology.

Natural and Pathological Aging Distinctively Impacts the Pheromone Detection System and Social Behavior

Molecular Neurobiology, 2022
AbstractNormal aging and many age-related disorders such as Alzheimer’s disease cause deficits in olfaction; however, it is currently unknown how natural and pathological aging impacts the detection of social odors which might contribute to the impoverishment of social behavior at old age further worsening overall health.

Reimagining pheromone signalling in the model nematode Caenorhabditis elegans. [PDF]

, 2017
Caenorhabditis elegans is an important, widely used developmental and genetic model. A pheromone has long been known to cause juvenile developmental arrest in C. elegans, a phenomenon that is common among nematodes more widely. Many novel effects of this
