“…In the majority of cases (95%) in which females resisted, the female was successful in dislodging the male before he adopted the final copulatory position. Such resistance by females to forced copulation attempts has been documented in virtually every species in which forced copulation has been described (see, for example, Thornhill 1980;Allen and Simmons 1996;Arnqvist 1997;McLain and Pratt 1999;Shuker and Day 2001;Hinn and Niedzlek-Feaver 2001). In most of these species, females are often successful in dislodging males.…”

Coercive Copulation in the Alpine Bushcricket Anonconotus alpinus Yersin (Tettigoniidae: Tettigoniinae: Platycleidini)

Sexual coercion in the form of forced copulation is widespread in the animal kingdom and has been documented in several insect taxa. In crickets and bushcrickets (sub‐order Ensifera), however, mating typically involves luring acts as opposed to forcing acts. The mating behaviour of the tettigoniid Anonconotus alpinus Yersin, which is described in this paper, appears to be unique amongst the Tettigoniidae (and possibly amongst the Ensifera) in that it is coercive, involving forced matings. Males did not stridulate immediately prior to mating but instead leapt on passing females, using their anal cerci as pincers to maintain a hold on the female's abdomen (which was sometimes damaged in the process). Males appeared to lack a sexual refractory period and attempted to copulate again as little as 18 s following the previous mating.

“…In Orthoptera, forced matings are characteristic of certain sub‐families within the sub‐order Caelifera (the grasshoppers etc.) (see, for example, Bland 1987; Riede 1987; Alexander et al 1997; Hinn and Niedzlek‐Feaver 2001). In the sub‐order Ensifera (crickets, bushcrickets etc.…”

“…Two years earlier, Pickford and Gillott () found the same in Melanoplus sanguinipes and a correlation between copulation duration and the number of transferred spermatophores. Hinn and Niedzlek‐Feaver () similarly found more than one transferred spermatophore after a single copulation in M. differentialis .…”

“…Further reasons for prolonged copulations may include in‐copula mate guarding (Alcock, ) or the possibility to transfer a larger ejaculate, which has been shown for the acridid grasshoppers Dichromorpha viridis (Johnson & Niedzlek‐Feaver, ), Melanoplus differentialis (Hinn & Niedzlek‐Feaver, ), and the desert locust Schistocerca gregaria (Dushimirimana, Hance, & Damiens, ; Pickford & Padgham, ). Pickford and Padgham () also demonstrated that males of S. gregaria regularly transfer not only more spermatozoa but also more than one spermatophore in a single copulation, which needs more time the more spermatophores will be produced and transferred.…”

Sex‐specific repeatabilities and effects of relatedness and mating status on copulation duration in an acridid grasshopper

In species with direct sperm transfer, copulation duration is a crucial trait that may affect male and female reproductive success and that may vary with the quality of the mating partner. Furthermore, traits such as copulation duration represent the outcome of behavioral interactions between the sexes, for which it is important—but often difficult—to determine which sex is in phenotypic control. Using a double‐mating protocol, we compared copulation durations between (1) virgin and nonvirgin and (2) sibling and nonsibling mating pairs in rufous grasshoppers Gomphocerippus rufus. Nonvirgin copulations took on average approximately 30% longer than virgin copulations, whereas relatedness of mating partners was not a significant predictor of copulation duration. Longer nonvirgin copulations may represent a male adaptation to sperm competition if longer copulations allow more sperm to be transferred or function as postinsemination mate guarding. The absence of differences between pairs with different degrees of relatedness suggests no precopulatory or preinsemination inbreeding avoidance mechanism has evolved in this species, perhaps because there is no inbreeding depression in this species, or because inbreeding avoidance occurs after copulation. Controlling for the effects of male and female mating status (virgin vs. nonvirgin) and relatedness (sibling vs. nonsibling), we found significant repeatabilities (R) in copulation duration for males (R = 0.33; 95% CI: 0.09–0.55) but not for females (R = 0.09; 95% CI: 0.00–0.30). Thus, copulation durations of males more strongly represent a nontransient trait expressed in a consistent manner with different mating partners, suggesting that some aspect of the male phenotype may determine copulation duration in this species. However, overlapping confidence intervals for our sex‐specific repeatability estimates indicate that higher sampling effort is required for conclusive evidence.

“…In Orthoptera, for female, multiple mating has many advantages [9]: preventing the females from sperm depletion [10], increasing the rate of oviposition [11][12][13][14][15], or providing material incorporated into eggs or female biomass [16,17]. Since the 1950, it has been shown that desert locust copulation occurs frequently, and multiple copulation appears to serve mainly as a stimulant to egg-laying [18].…”

The multiple mating by female (polyandry) is a widespread behavior in insect species. This behavior is known to be a kind of itness maximization, but some case of sexual selection factors can explain the evolution of this behavior in relation with the phenotype plasticity model. In this paper, we analyze the role of polyandry in the reproductive success and in the phase shift process in the gregarious desert locust. In an applied perspective, knowledge on the reproductive success and in the phase shift process is essential to perform mass rearing for human food production. Our results suggest that multiple mating is not associated with itness beneits. Polyandry acts as a signal of phase shift through ofspring. We showed that hatchlings of gregarious females mated only once are smaller and green at 87.2% in irst egg pods and produced the solitary form of the desert locust. The coloration of ofspring in females mated with two males reaches only 15.2% of green forms versus 84.8% of mostly blacks. In this study, we showed that females mated more than two times with diferent males produce larger eggs, heavier, and black hatchlings characteristic of gregarious phase known in S. gregaria.
