“…Females visit individual males at the lek. The males then perform a courtship dance that involves at least five main elements (FCron, 1962;Harris, Wood & Bailey, 1986;Arita & Kaneshiro, 1985,1989Briceno, Ramos & Eberhard, 1996): these are (1) pheromone signalling (or calling); (2) wing vibration (or fanning); (3) head-shaking (or rocking); (4) wing flapping (or buzzing); (5) malejump (immediately prior to copulation). There are also acoustical stimuli (Webb et a[., 1983).…”

Sexual selection is known to operate at medfly leks with a few males gainiig a high proportion of matings. However, specific male characteristics subject to sexual selection have not been identified. Here we report laboratory studies indicating that directional sexual selection operates on the level of fluctuating asymmetry (FA) in the superior frontal orbital setae (sex setae), with symmetrical males gaining more matings. Studies relating mating success with FA in a male trait have generally been taken as evidence of the operation of indirect sexual selection. For a male trait to acts as a reliable indicator of fitness, FA in the male trait should be negatively associated with trait size and females should mate with the males with the most exaggerated form of the trait. However no association was found between seta FA and mean seta length. In addition sexual selection did not appear to operate on mean trait size, although males with an intermediate sex seta to wing length ratio did achieve higher mating success, indicating that stabilizing sexual selection operates on this relative dimension. It is suggested that differences in male competitive ability may provide an alternative explanation of how such associations between mating success and FA in male characteristics can arise. 0 I998 The Linnean Society of London ADDITIONAL KEY WORDS:-mating successsex setaemedflywing length -

“…Inadvertent selection on other traits, inbreeding, and genetic drift could counteract the effect of selection. Based on previous results (Harris et al, 1986;McInnis et al, 2002;Rull et al, 2015;Bosa et al, 2016;Quintero-Fong et al, 2016), the potential of selection in colony management to improve field performance of sterile males could not be discarded, but questions regarding the optimal population size and selection strength should be addressed.…”

The sterile insect technique (SIT) has been applied successfully for the control of several fruit fly species of economic importance. In species with lek mating systems, as in the Mexican fruit fly, Anastrepha ludens (Loew) (Diptera: Tephritidae) -where the variance in male mating success is high, males have to compete with other males, and where wild females are highly selective -the success of SIT depends on the sexual competitiveness of mass-reared sterile males. However, mass-rearing conditions result in selection of sexual behavioral traits that differ from wild flies, reducing mating competitiveness of sterile flies and SIT efficiency. Artificial selection in mass-rearing colonies, based on male mating success, represents an alternative to improve the sexual performance of sterile males. Here, we evaluated the effect of selection of A. ludens mass-reared males based on their mating competitiveness. Two modes of selection were compared, one single selection event on parental flies, and continuous selection along four consecutive generations. For the offspring of each treatment in each generation, we evaluated male mating success, its association with post-copulatory behavior through female remating inhibition, and life-history traits that are key for mass-rearing, such as immature survival and reproduction. Field cage mating tests revealed that wild males were more competitive than mass-reared males (selected and unselected). Although no significant differences were found between mass-reared selected and non-selected males, in the fourth generation males from the selected colonies performed better than males from the non-selected colonies and their mating competitiveness was similar to that of wild males. No consistent differences were observed in mating latency, copulation duration, or ability to inhibit female remating. Survival and fecundity decreased with increasing rearing generations, except in the colony with continuous selection where fecundity and fertility increased.

“…Details of courtship (vibration distance and vibration duration) were also different. Other detailed changes in courtship were associated with the direction of selection, the most obvious being a failure to proceed from courtship to successful copulation in slow selected lines (Harris et al 1986).…”

“…It reports observations on changes in courtship behaviour and 'startle activity' in the selected lines, with particular reference to the influence of the selection method, independent of the direction of selection. Further differences between the selected lines in details of courtship, related to the direction of selection, will be dealt with in a separate paper but have been reported in outline by Harris et al (1986). The base stock on which all selection experiments were carried out was obtained by crossing Italy (in laboratory generation F23) with Costa Rica (in laboratory generation F27).…”

No significant variation in mating activity was observed among eight laboratory strains of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Two methods were used to select strains showing high and low mating activity: a single pair technique (SP) assessing ‘time to mating’ and a mass technique (M) based on a ‘mating index’. Reciprocal pairings between fast and slow selected lines showed that the difference between the SP lines was female‐determined whereas the difference between the M lines depended on the behaviour of both sexes. M selection, irrespective of its direction, affected two courtship parameters, ‘vibration distance’ and ‘vibration duration’ both of which tended to be shorter. M selection was also associated with a reduction in ‘startle activity’ in females. Résumé Deux méthodes de sélection de la mouche méditerranéenne des fruits, Ceratitis capitata (Diptera: Tephritidae), en fonction de leur comportement sexuel: réponse à la sélection et influence de la méthode de sélection Aucune variation significative n'a été observée dans les activités sexuelles de huit souches de laboratoire de la mouche méditerranéenne du fruit, Ceratitis capitata (Wiedemann) (Diptera Tephritidae). Deux méthodes ont été utilisées pour sélectionner des souches manifestant une activité sexuelle basse ou élevée: une technique utilisant un seul couple (SP), basée sur la durée de la période avant copulation, et une technique de masse (M), basée sur un ‘index d'accouplement’. Des appariements réciproques entre les lignées rapides et lentes ont montré que la différence entre les lignées SP était déterminée par les femelles, tandis que la différence entre les lignées M résultait du comportement des deux sexes. La sélection M, quelle que soit sa direction, affects deux paramètres, la ‘distance entre partenaires lors de la vibration’ et la ‘durée de la vibration’ qui tous deux tendent à se raccourcir. La sélection M est aussi associée à une réduction de la réaction des femelles à un brusque stimulus lumineux ('Startle activity').
