摘      要：Psyllids,or jumping plant lice(Hemiptera:Sternorrhyncha:Psylloidea),are a group of small phytophagous insects that include some important pests of crops *** communication of psyllids occurs via vibrations transmitted through host plants,which play an important role in mate recognition and *** signals are species-specific and can be used to aid in psyllid taxonomy and pest ***-eral hypotheses have been proposed for the mechanism that generates these vibrations,of which stridulation,that is,friction between parts of the forewing and thorax,has re-ceived the most *** have investigated vibrational communication in the Euro-pean pear psyllid species Cacopsylla pyrisuga(Foerster,1848)using laser vibrometry and high-speed video recording,to directly observe the movements associated with signal *** describe for the first time the basic characteristics of the signals and signal emission of this *** on observations and analysis of the video recordings us-ing a point-tracking algorithm,and their comparison with laser vibrometer recordings,we argue that males of *** produce the vibrations primarily by wing buzzing,that is,tremulation that does not involve friction between the wings and *** observed signal properties with previously published data,we predict that wing buzzing is the main mechanism of signal production in all vibrating psyllids.
