摘要
Study on the behaviour and mechanism acoustic communication (AC) in rice planthoppers (RPHs) have been conducted at CNRRI and Hangzhou Applied Acoustic Research Institute since 1986. Researchers have developed techniques for monitoring and playing back the acoustic signal (AS) of RPHs, and have made important breakthroughs in several aspects of AC. The study proved that the stridulating organ is on both sides of the juncture of pterothorax and abdomen of adult RPHs, and the AS were produced by convolution homomorphic system. On the acoustic ana. lysis of ASs, not only was the wavcform of ASs analysed, but also the spectrum of ASs was studied more
