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
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.
