Introducing a turbulence...

... aspects of beetle biology: (1) an energetic trade-off between flight distance and host colonisation capacity; and (2) the relationship between flight distance and pheromone production. A 23 h flight treatment was applied to a subset of beetles using computer-linked flight mills. After flight treatment...

... tracking Pheromone Ants exhibit remarkably sophisticated and diverse mechanisms of navigation that make use of both internal and external cues ( Knaden and Graham, 2016 ). Sensory signals for navigation come through many modalities, including sight ( Narendra et al., 2017 ; Graham and Philippides...

... the dorso-lateral compound eye, they continued to perform visually driven steering responses as if their eyes were free of paint. Vickers and Baker (1994) found that male H. virescens moths located a source of female pheromone at the highest proportion when visual patterns (i.e. dark spots on a light...

... that individuals can change the behaviour of other worms via pheromones and mechanosensory interactions. In particular, pheromones affect foraging behaviour, so that the chemotactic behaviours of individuals in a group (population) can be modulated by interactions with other individuals in the population...

... are largely unknown. To better understand how host cues affect P. pacificus embryogenesis, we characterized the threshold of sensitivity to the pheromone ( Z )-7-tetradecen-2-one (ZTDO) by determining the minimum exposure duration and developmental window that results in P. pacificus embryonic lethality. We...

... potent than that from hatchery-bred females. Taken together, these results strongly suggest that faeces- and urine-released odorants are involved in reproduction in the Senegalese sole, and establish a basis for further investigation into pheromonal communication in marine teleosts. * Author...

...Tyler J. Buchinger; Ke Li; Mar Huertas; Cindy F. Baker; Liang Jia; Michael C. Hayes; Weiming Li; Nicholas S. Johnson ABSTRACT Animals rely on a mosaic of complex information to find and evaluate mates. Pheromones, often consisting of multiple components, are considered to be particularly important...

... are species specific. Dominant male Mozambique tilapia [ Oreochromis mossambicus (Peters 1852)] release a sex pheromone, 5β-pregnan-3α,17α,20β-triol 3-glucuronate and its 20α-epimer, via their urine. The objective of this study was to assess the sensitivity, specificity and versatility of the olfactory system...

...Andreas Simon Brandstaetter; Florian Bastin; Jean-Christophe Sandoz During the mating season, honeybee males, the drones, gather in congregation areas 10–40 m above ground. When a receptive female, a queen, enters the congregation, drones are attracted to her by queen-produced pheromones and visual...

...Michiya Kamio; Manfred Schmidt; Markus W. Germann; Julia Kubanek; Charles D. Derby Female blue crabs ( Callinectes sapidus ) in their pubertal moult stage release unidentified sex pheromone molecules in their urine, causing males to respond with courtship behaviours including a display called...

...Adrian A. Smith; Jocelyn G. Millar; Lawrence M. Hanks; Andrew V. Suarez SUMMARY Contact pheromones in the form of cuticular hydrocarbons are widespread among insects. Eusocial insects present a special challenge for understanding the evolution of the cuticular hydrocarbon profile because this blend...

...Fernando Guerrieri; Cesar Gemeno; Christelle Monsempes; Sylvia Anton; Emmanuelle Jacquin-Joly; Philippe Lucas; Jean-Marc Devaud SUMMARY Sex pheromones are intraspecific olfactory signals emitted by one sex to attract a potential mating partner. Behavioural responses to sex pheromones are generally...

...Alejandra Bazáes; Oliver Schmachtenberg SUMMARY Teleost fish lack independent olfactory organs for odorant and pheromone detection. Instead, they have a single sensory epithelium with two populations of receptor neurons, ciliated and microvillous, that are conserved among vertebrates, and a unique...

... glycosylation mannose pheromone The settlement-inducing protein complex (SIPC) is a contact pheromone that has been identified as the primary mediator of gregarious settlement in the barnacle Balanus amphitrite , though other chemical signals are involved ( Clare, 2011 ). Barnacles are a key...

...Tsung-Han Kuo; Joanne Y. Yew; Tatyana Y. Fedina; Klaus Dreisewerd; Herman A. Dierick; Scott D. Pletcher SUMMARY Attractiveness is a major component of sexual selection that is dependent on sexual characteristics, such as pheromone production, which often reflect an individual’s fitness...

... study species, the red-sided garter snake ( Thamnophis sirtalis parietalis ), is a model vertebrate for studying hormonal control of chemical signals because males completely rely on the female sex pheromone to identify potential mates among thousands of individuals. How sex hormones can influence...
