【摘要】 采用电子记录的方法 ,并结合蜜露量和产卵量测定 ,研究了白背飞虱在春江 0 6,Rathu Heenati(RHT)和明恢63上的取食和产卵行为。结果表明 :白背飞虱在 RHT和春江 0 6上的取食刺探频率显著高于明恢 63,且取食韧皮部的时间明显少于明恢 63;RHT和春江 0 6对白背飞虱具有很强的拒取食作用 ,明恢 63则较感虫 ;白背飞虱产卵的次数、每次持续时间、总时间及产卵量都不存在品种间的显著差异 ,具有杀卵作用的只有春江 0 6。春江 0 6具有杀卵和抑制取食两种抗虫性机制 ,RHT只具有抑制取食的机制 ,明恢 63是感虫的杂交稻恢复系更多还原

【Abstract】 Feeding and oviposition behavior of the whitebacked planthopper, Sogatalla furcifera, were electronically monitored on rice varieties of Chunjiang 06, Rathu Heenati (RHT) and Minghui 63. Honeydew amount, number of total eggs were also determined. Experimental results revealed that: among these three varieties, the frequency of exploratory probing of S. furcifera on RHT and Chunjiang 06 was much higher than that on Minghui 63, and the phloem ingestion duration was much shorter; Chunjiang 06 and Rathu Heenati showed strong feeding inhibition activity to S. furcifera, while Minghui 63 was susceptible; the number of total eggs, oviposition times, and average duration and total time of oviposition of S. furcifera were not significantly different on the three rice varieties, Chunjiang 06 showed ovicidal and feeding inhibition resistance, Rathu Heenati showed feeding inhibition resistance, Minghui 63 was a susceptible restorer line of hybrid rice.更多还原
