Determining Factor

The Persian boxer mantid, Holaptilon brevipugilis, is the mantid most recently described from Iran. Here, I present some aspects of the courtship display and mating behavior of this species. I conducted 28 mating trials, quantified the relative frequency of all mating behaviors, and estimated the pre-copulation, copulation, and post-copulation periods. I also compared the effects of frontal vs. lateral approaches of the male for mating success, since frontal approach increases the risk that the male will be seen and cannibalized by the female. In 64% of trials, the male approached the female immediately, regardless of whether the female could see him or not. Copulation was successful in 61% of trials. Male courtship consisted of dorsoventral bending of the male’s abdomen and occurred in 10% of all trials, but only when the female was facing the male. In contrast, trembling of the forelimbs was not associated with copulation, occurred in 10% of all trials, and was always followed by the male moving away from the female. I observed one female cannibalizing a male post-copulation. The Persian boxer mantid might be sexually cannibalistic, but confirming this hypothesis would require further studies, including a focus on female hunger level as a determining factor in sexual cannibalism and in male courtship behaviors.

The Face

Pre-copulatory sexual cannibalism, or cannibalism without mating, is expected to promote the evolution of male strategies that enhance mating success and reduce the risk of cannibalism, such as preferential mating with feeding females. However, sexual selection on male competitiveness may alter male courtship decisions in the face of cannibalism risk. We investigated the effect of prey availability and rival presence on male mating decisions in the highly cannibalistic Springbok mantis, Miomantis caffra. We found that males approached females more rapidly and mated more often in the presence of prey, suggesting that females distracted with foraging may be less of a threat. The presence of a rival also hastened the onset of copulation and led to higher mating success, with very large effects occurring in the presence of both prey and rivals, indicating that intrasexual competition may intensify attraction to foraging females. Taken together, our results suggest that pre-copulatory cannibalism has selected for male preference for foraging females, and that males adjust their mating strategy to both the risk of competition and the threat of cannibalism.

Sexually reproductive insects exhibit diverse mating behaviors. However, the mating pattern remains unknown for Panorpodes of Panorpodidae to date. In this study, we investigated the mating behavior and copulatory mechanism of the short-faced scorpionfly Panorpodes kuandianensis Zhong, Zhang and Hua, 2011 for the first time. The results show that the male provides a salivary mass as a nuptial gift to the female and starts to copulate with the female in a V-shaped position, then changes to an end-to-end position by temporarily twisting the female abdominal segments VII−IX by 180°. During mating the basal processes and the basal teeth of the gonostyli and the hypandrium are used to obtain copulation and sustain the coupling of genitalia to secure successful sperm transfer. This unique mating pattern is greatly different from that of other Mecoptera reported and is likely evolved as an adaptation in the context of sexual conflict.

AbstractWe studied the role of male courtship behaviour in female mate choice in red jungle fowl (Gallus gallus), the ancestor of domestic chickens. The traits most highly correlated with behavioural displays were those most relied upon by females in making mate choice decisions. These traits (comb length, comb colour, eye colour, and spur length) are highly condition-dependent in jungle fowl. Females chose males that displayed at a greater overall intensity in the period after the female was allowed to interact with the males (post-release), but were indifferent to displays during the period before the female could approach the roosters (pre-release). After accounting for the effect of morphology on mate choice, waltzes were the only display that explained a significant amount of variation in male mating success. Chosen and rejected males had different display rates even when the female was not present. Plasma testosterone level was correlated with pre-release behaviours, but not with post-release behaviours or mating success.

AbstractFemale green anoles, Anolis carolinensis, were paired in terraria to investigate behavioral components of social interaction. Resources (perching sites, prey, and males as potential mates) were limited to assess their importance to cohabiting females. During interaction, paired females exhibited aggressive social behavior which contributed to the development of dominant-subordinate relationships. Dominant status and its relationship to differential resource acquisition was defined primarily by frequency of displacement of another female. Along with displacement, dominant females also had increased frequency of assertion displays, challenge displays, attacks and biting (Figs 1 & 2). Subordinate females were displaced more often and assumed submissive postures. No differences were found between dominant and subordinate females for perch site selection, body color or in prey capturing latency or success (Figs 3 & 4). Perch site elevation was not different between dominant and subordinate females, but was significantly lower than males. The color of paired females was not different unless males were present, in which case dominant females were darker. Paired females also respond differently to courtship display (Fig. 5). Dominant females responded with displays significantly more often than subordinate females to male courtship, indicating receptivity. The role of dominant-subordinate relationships among female A. carolinensis may include courtship and reproductive success as an important component, with consequences for the outcome of aggressive and reproductive social interactions with males.

SUMMARY To determine whether the display of male courtship behaviour depends on the action of androgen on discrete areas of the brain, single crystalline implants of testosterone propionate (TP) (mean weight 40 μg) were positioned unilaterally in the brains of castrated male Barbary doves. Implants in the preoptic, anterior hypothalamic and lateral hypothalamic areas induced the full courtship display consisting of chasing, bowing and nestsoliciting. None of these behaviour patterns was re-established at precastration levels measured in terms of duration of display. Durations of courtship displayed by implanted males were similar to those induced by daily intramuscular injections of TP (300 μg/day × 15) into castrated birds. The effectiveness of implants of TP into other regions of the brain could be related to their proximity to the preoptic and anterior hypothalamic regions. There were marked deficits in the pattern of courtship of castrated doves with implants in areas adjacent to the preoptic and anterior hypothalamic regions — the neostriatum intermediale, the area basalis, and posterior hypothalamus; implants more distantly placed in the paleostriatum primitivum and lateral forebrain bundle area did not induce courtship behaviour. Cholesterol implants (59 μg) and blank implant tubing in the preoptic and anterior hypothalamic areas did not affect behaviour. The results obtained were not specific for TP implants; chasing and nest-soliciting displays were also induced by either testosterone implants (51 μg) or oestradiol-17β monobenzoate implants (47 μg). In both cases, the courtship display lacked bowing. It is concluded that the preoptic and anterior hypothalamic areas are directly sensitive to testosterone and that these areas are associated with the control of courtship behaviour.

Abstract Many studies have identified the reproductive benefits of cooperative behaviors, yet few have identified the mechanisms that underlie these behaviors. Mechanistic studies can inform our understanding of why some individuals are more or less cooperative, as well as identify the physiological constraints imposed upon the evolution of reproductive traits. Male wire-tailed manakins (Pipra filicauda) exhibit cooperative courtship behaviors and more cooperative territory holders have been shown to exhibit higher reproductive success. To begin to understand the proximate basis of cooperative display behaviors, we conducted both an observational study and an experimental study. Because coordinated courtship displays underlie this form of cooperation, our study also examined both the hormonal and social drivers of individual variation in courtship behavior more broadly (e.g., courtship display rates). Our observational study revealed that males with higher testosterone levels performed fewer cooperative display bouts. In addition, our experimental study demonstrated that the proportion of a male’s courtship displays that were cooperative decreased after being administered a testosterone-filled hormone implant. We found no relationship between an individual’s courtship display effort (i.e., display rate and time spent performing courtship displays) and circulating testosterone in either study. However, more cooperative males spent a greater proportion of time performing courtship displays than did less cooperative males, suggesting that testosterone may indirectly mediate courtship display behaviors by influencing a territory holder’s cooperative behavior. Overall, both our observational and experimental results suggest that reduced cooperative behavior is a cost of maintaining high levels of testosterone for territory-holding males.
