Abdominal-B Neurons Control Drosophila Virgin Female Receptivity
<p>To choose their mates, male and female vinegar flies (Drosophila melanogaster) perform a duet of stereotyped, sexually dimorphic courtship behaviors, a suite of sensory back-and-forth that offers an excellent model for studying the neural circuitry of complex behavior (Dickson, 2008). However, …

Neural Regions Affecting Female Aggression and Receptivity in Drosophila melanogaster
… behaviour. Examples of such behaviours include female aggression and receptivity to male courtship. Silencing a candidate region called the mushroom body (MB) was found to decrease female receptivity. Additionally, silencing a specific subset of the MB, the alpha/beta lobes, was also found to …

Effects of male breeding gland in hymenochirus on female reproductive output
… release pheromones that attract conspecific females. This thesis shows the pheromones also stimulate the reproductive system of conspecific females. Females exposed to normal males prior to mating then allowed to mate with the normal males released a higher number of eggs than females who …

The circuit basis of olfactory mate recognition and localisation
… a neural hub for sexual behaviours - including female receptivity. We imaged the activity of sensory neurons and second order PNs in the cVA pathway while presenting the female with a male fly at defined positions and asked what features of the stimulus can be decoded from neuronal activity. We …

The Effects of Progesterone on Extracellular Serotonin Levels in Rat Hypothalamus
… VMN and MCG contribute to the facilitation of female receptivity.

A sexually dimorphic circuit switch in higher olfactory centres
… (cVA) elicits different behaviours in males and females: while males are repelled by cVA, it stimulates female receptivity. However, olfactory receptor neurons and their second-order partners, the olfactory projection neurons, do not show significantly different physiological responses to cVA. …

The effect of environmental and social factors on the courtship and mating dynamics of the smooth newt, Triturus v. vulgaris
… oxygen availability not limiting. In the wild females determine the timing of mating. They are highly receptive for a brief period after arrival at the breeding site (early spring), subsequently re-mating only sporadically. Therefore, few courtships take place at mid-season, optimal …

The behavioural function of pheromones in crayfish
… and receiver response.Urine release by male and female crayfish was found to coincide with aggressive behaviours rather than reproductive behaviours. Female urine release was essential for initiating mating, with males detecting female receptivity by spying on hormones and metabolites released …

Aspects of the Behavioural Ccology of Stegobium paniceum (L.) (Coleoptera Anobiidae)
… authors) was found to be situated in the female abdomen. The mating efficiency of both sexes was found to increase steadily with age after adult eclosion, reaching a peak at 9 days. Female pheromone production/release was significantly reduced after 3 minutes in copula, as was female …

Connecting Female Mating Decisions and Male Courtship Strategies in Drosophila
… evolved elaborate behavioral patterns to attract females or repel rival males. The neural mechanisms mediating these male behavioral traits and how females use them to guide their mating decisions remain elusive. In this thesis,I present our efforts to uncover the neural logic underlying mate …
