雄性稻绿蝽对雌性鸣唱反应的物种特异性

雌性稻绿蝽的鸣唱开始了在基质中产生的通讯并引起雄性不同的特定反应。在两种自然情况下 ,我们检验了雄性稻绿蝽对N viridula ,Thyantapallidovirens和Thyantacustatoraccerra个体鸣唱刺激反应的物种特异性水平 ,并对反应强度和同种及异种刺激性鸣唱的时间特性进行了相关分析 ,证明雄性求偶鸣唱的发送和震动源的定位是最具物种特异性的反应。然而 ,即便是在这个水平上 ,雄性稻绿蝽不能将同种雌性个体的鸣唱与T .custatoraccera的第二个雄性个体的鸣唱区分开来 ,后者与前者有相似的脉冲持续时间和重复时间值。本文也讨论了涉及交配行为鸣唱期的有关信号的物种特定性的概念

Species specificity of male southern green stink bug Nezara viridula (L.) reactions to the female calling song

The female southern green stink bug Nezara viridula (Heteroptera:Pentatomidae)calling song starts substrate borne communication and triggers different stereotyped responses in males.We tested the species specificity level of male N viridula responses to stimulation with songs of N viridula,Thyanta pallidovirens and Thyanta custator accerra (Heteroptera:Pentatomidae)in two natural situations and correlated the response magnitude with temporal properties of the conspecific and heterospecific stimulatory songs.Emission of the male courtship song together with locating of the vibration source proved to be the most species specific reaction.However,even at this level males did not discriminate between the conspecific female calling song and second male calling song of T custator accera ,which have similar pulse duration and repetition time values.The concept of species specificity of signals involved in the calling phase of mating behaviour is discussed
