... studies suggest that Drosophila can also use path integration to return to a food reward. However, the existing experimental evidence for path integration in Drosophila has a potential confound: pheromones deposited at the site of reward might enable flies to find previously rewarding locations even...

...Nigel R. Franks; Jacob A. Podesta; Edward C. Jarvis; Alan Worley; Ana B. Sendova-Franks ABSTRACT We used a robotic gantry to test the hypothesis that tandem running in the ant Temnothorax albipennis can be successful in the absence of trail laying by the leader . Pheromone glands were placed...

.... In walking carpenter ants, exposure to formic acid (FA), an alarm pheromone, improves the accuracy of nestmate recognition by decreasing both alien acceptance and nestmate rejection. Here, we studied the effect of FA exposure on the spontaneous aggressive mandible opening response (MOR) of harnessed...

...Moshe Nagari; Yafit Brenner; Guy Bloch ABSTRACT ‘Nurse’ honeybees tend brood around the clock with attenuated or no circadian rhythms, but the brood signals inducing this behavior remain elusive. We first tested the hypothesis that worker circadian rhythms are regulated by brood pheromones. We...

... Pheromones Sex pheromone Social insects The cuticular chemical profiles of social insects encode information necessary for maintaining colony identity and social cohesion, providing the foundation through which eusociality is maintained ( Blomquist and Bagnères, 2010 ). Signals of colony membership...

... roles of visual and chemosensory cues in the mate recognition behavior of fruit flies ( Drosophila melanogaster ) using a robotic fly dummy that was programmed to interact with individual males. By pairing male flies with dummies of various shapes, sizes and speeds, or coated with different pheromones...

... neurons. In Aplysia , mate attraction and subsequent reproduction is initiated by responding to a cocktail of water-borne protein pheromones released by animal conspecifics. We show that the rhinophore contraction in response to pheromone stimulants is significantly altered following phospholipase C...

... may be induced by different types of skin odorants and how well the odorants from injured conspecifics are distinguished from other species. The OB of crucian carp shows a clear chemotopy as units located in different regions respond to either food-related odorants, to pheromones or to alarm odorants...

... unexplored. In this review, I summarize the various factors that are known to affect female receptivity in the Lepidoptera to date, and briefly compare the function and similarity of the Pheromone Suppressing Peptide ( Hez PSP) in moths to that of the Sex Peptide in Drosophila melanogaster ( Drm SP...

.... The literature suggests that male abdominal tergites are the site of sex pheromone production. In nymphs as well as adults, the conductances of all areas, except the antennae of males, decreased following dehydration and a decline in animal water content. In most cases the magnitude of the decrease was tightly...
