摘　　要：Psyllids,or jumping plant lice(Hemiptera:Sternorrhyncha:Psylloidea),are a group of small phytophagous insects that include some important pests of crops world-wide.Sexual communication of psyllids occurs via vibrations transmitted through host plants,which play an important role in mate recognition and localization.The signals are species-specific and can be used to aid in psyllid taxonomy and pest control.Sev-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 attention.We 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 pro-duction.We describe for the first time the basic characteristics of the signals and signal emission of this species.Based 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 C.pyrisuga produce the vibrations primarily by wing buzzing,that is,tremulation that does not involve friction between the wings and thorax.Comparing observed signal properties with previously published data,we predict that wing buzzing is the main mechanism of signal production in all vibrating psyllids.
