Resumen:
The use of acoustic signals by males during courtship and mating is wellknown. Nevertheless, their association with female unwillingness tomate is much less studied. In spiders, stridulation during sexual interactionsis relatively common in some groups, but mainly restricted tomales. In the pholcid spider Holocnemus pluchei, both sexes have stridulatoryorgans. The aims of the present work were (1) to establish whetherfemale stridulation occurs during intra- and inter-sexual interactions,(2) to determine whether female reproductive status affects the likelihoodthat she will stridulate and (3) to determine whether female stridulationis influenced by male sexual behaviour. We found that femalestridulation usually occurs both during intrasexual interactions and,most frequently, during intersexual interactions. Females with moreprevious matings stridulated more frequently. Stridulation intensity washigher in females that did not accept new copulations compared withthose that copulated. Female stridulation did not vary in elaborated andnon-elaborated courtship. Thus, females use stridulation to communicatelevels of sexual receptivity. It is also possible that females use stridulationto indirectly assess male ability to persist and persuade.
