Hard-shell mating in Neohelice granulata: the role of ecdysone in female receptivity and mate attraction
(Springer, 2017-03-01)
Most brachyuran females become receptive during the intermolt period, a condition considered “derived”. However, as far as we know, studies testing the existence and function of pheromones in decapods are based on species ...
The sexual behaviour of chagas' disease vectors: Chemical signals mediating communication between male and female triatomine bugs
(Hindawi Publishing Corporation, 2012-01)
Chemical communication mechanisms that mediate sexual behaviour in triatomine bugs are reviewed with regard to source, identity, and function of sex pheromones. Males attempt to copulate but may be rejected, depending on ...
GPCR receptor phosphorylation and endocytosis are not necessary to switch polarized growth between internal cues during pheromone response in S. cerevisiae
(Taylor & Francis, 2020-08-20)
Chemotactic/chemotropic cells follow accurately the direction of gradients of regulatory molecules. Many G-protein-coupled receptors (GPCR) function as chemoattractant receptors to guide polarized responses. In “a” mating ...
Effects of Synthetic Acaricides and Nosema ceranae (Microsporidia: Nosematidae) on Molecules Associated with Chemical Communication and Recognition in Honey Bees
(MDPI, 2020-12)
Acaricides and the gut parasite Nosema ceranae are commonly present in most productivehives. Those stressors could be affecting key semiochemicals, which act as homeostasis regulators inApis mellifera colonies, such as ...
Trail-laying behaviour as a function of resource quality in the ant Camponotus rufipes
(Hindawi Publishing Corporation, 2011-04)
Chemical trails have been shown to act as an orientation cue in some ant species. Here, I report that the trail-laying behaviour in the nectar-feeding ant, Camponotus rufipes, varies with the concentration of the sucrose ...
Sex pheromone component produced by microbial associates of the forest pest Megaplatypus mutatus
(Wiley Blackwell Publishing, Inc, 2019-03)
Megaplatypus mutatus (Chapuis) (Coleoptera: Platypodidae) is an ambrosia beetle native to South America that causes economic loss and was recently introduced to Italy, where it attacks and damages live poplar trees. Sulcatol ...
Evaluation of sex pheromone formulations to attract Spodoptera frugiperda (Lepidoptera: Noctuidae) adult males in ArgentinaEvaluación de formulaciones de feromona sexual para la atracción de machos de Spodoptera frugiperda (Lepidoptera: Noctuidae) en Argentina
(Sociedad Entomológica Argentina, 2019-09)
Spodoptera frugiperda (Smith) es la plaga más importante del maíz en Argentina.En América su monitoreo se realiza con trampas cebadas con feromona sexual femenina sintética. Tal monitoreo tiene éxito variable, principalmente, ...
Electrophysiological and behavioural response of Aedes albopictus to n-heinecosane, an ovipositional pheromone of Aedes aegypti
(Wiley Blackwell Publishing, Inc, 2014-03)
Aedes aegypti (L.) and Aedes albopictus (Skuse) (Diptera: Culicidae) are highly anthropophilic mosquito species and potential vectors of dengue and yellow fever. The location of suitable sites for oviposition requires a ...
Incipient speciation revealed in Anastrepha fraterculus (Diptera; Tephritidae) by studies on mating compatibility, sex pheromones, hybridization, and cytology
(Wiley Blackwell Publishing, Inc, 2009-05)
It has long been proposed that the nominal species Anastrepha fraterculus is a species complex and earlier studies showed high levels of pre-zygotic isolation between two laboratory strains from Argentina and Peru. Further ...
Co-option of neurotransmitter signaling for inter-organismal communication in C. elegans
(Nature, 2019-07-18)
Biogenic amine neurotransmitters play a central role in metazoan biology, and both their chemical structures and cognate receptors are evolutionarily conserved. Their primary roles are in cell-to-cell signaling, as biogenic ...
