Uncovering mate choice and factors that lead to the choice are very important to understanding sexual selection in evolutionary change.Cicadas are known for their loud sounds produced by males using the timbals.However,males in certain cicada species emit 2 kinds of sounds using re-spectively timbals and stridulatory organs,and females may produce their own sounds to respond to males.What has never been considered is the mate choice in such cicada species.Here,we in-vestigate the sexual selection and potential impact of predation pressure on mate choice in the ci-cada Subpsaltria yangi Chen.It possesses stridulatory sound-producing organs in both sexes in addition to the timbals in males.Results show that males producing calling songs with shorter tim-bal-stridulatory sound intervals and a higher call rate achieved greater mating success.No mor-phological traits were found to be correlated with mating success in both sexes,suggesting neither males nor females display mate preference for the opposite sex based on morphological traits.Males do not discriminate among responding females during mate searching,which may be due to the high energy costs associated with their unusual mate-seeking activity and the male-biased predation pressure.Females generally mate once but a minority of them re-mated after oviposition which,combined with the desirable acoustic traits of males,suggest females may maximize their reproductive success by choosing a high-quality male in the first place.This study contributes to our understanding mechanisms of sexual selection in cicadas and other insects suffering selective pressure from predators.
