【摘要】 褐稻虱Nilaparvata lugens(Stal)雌、雄成虫均能振动腹部,发出由固体介质(寄主植株)传递的声信号,用于交尾前的个体间通讯。整个发声过程似为卷积同态系统,包括:冲激序列发生器、腹部振动单元、后基片振动单元及机械滤波嚣。最近发现的摩擦发声器是该系统的核心。根据上述发声模型,用电子振荡电路成功地模拟了褐稻虱雌虫鸣声。更多还原

【Abstract】 Sexual recognition and communication in Nilaparvata lugens(St(?)l)depended entirely onsubstrate-transmitted acoustic signals.The presence of stridulating organs both in males and females wasdiscovered recently.Signals are produced by a convolution homomorphic system,and the stridulating or-gan forms the hub of the system.Based on the model of signal production,analogues of female signal ofN.lugens were made successfully using an electron simulator system.更多还原
