摘      要：The rice planthoppers,Nilaparvata lugens and Sogatella furcifera,are important sap-sucking pests of rice in *** mesoionic insecticide tifumezopyrim was previously shown to be highly effective in controlling both *** and *** this study,electropenetrography(EPG)was used to evaluate the effect of three triflumezopyrim concentrations(LC。LC。and LC)on the feeding behavior of *** and *** signals of planthoppes indicated that there were six different waveforms NP,N1,N2,N3,N4,and N5,which corresponded to non-penetration,stylet penetration into epidermis,salivation,extracellular movement of stylet,sap ingestion in phloem,and water ingestion in xylem during *** to untreated controls,triflumezopyrim at LC。and LC。prolonged the duration of the non-penetration period by 105.3 to 333.7%.The probing frequencies of *** exposed to tiflumezopyrim at LC1。and LCso were significantly increased;however,the probing frequencies of *** showed a significant decrease when exposed to triflumezopyrim at all *** exposure prolonged the duration of salivation and shortened the duration of extracellular *** duration of phloem sap ingestion decreased from 37.2 to 77.7%in the LCgo and LCgo treatments,*** in feeding behavior in response to triflumezopyrim and pymetrozine were *** summary,the results show that the LC。and LCgo concentrations of trflumezopyrim inhibit the feeding activities of *** and *** mainly by prolonging the duration of non penetration and by shortening the duration of phloem sap ingestion,which may foster more efficient use of triflumezopyrim in Asia.
