水稻品种对黑肩绿盲蝽功能反应的影响

Effect of Rice Varieties on Functional Responses of Cyrtorhinus lividipennis(Reuter)

在室内研究了以不同水稻品种上褐飞虱 (N ilaparvata lugens)为食的黑肩绿盲蝽 (Cyrtorhinus lividipennis)对褐飞虱卵的功能反应。结果表明 ,以 TN1、IR2 6、IR6 4和丙 97- 34等 4个品种上褐飞虱为食的黑肩绿盲蝽的功能反应均显著地强于以丙 97- 5 9上褐飞虱为食的黑肩绿盲蝽的 ,而在前面的 4个品种间则差异不明显。统计分析表明 ,由丙 97- 5 9上所育出的黑肩绿盲蝽对猎物的处理时间显著或极显著地长于由其他 4个品种上所育出的 ,而瞬时攻击率则在 5个品种上所育出的黑肩绿盲蝽间差异不显著 ,这说明导致不同品种上育出的黑肩绿盲蝽功能反应差异的原因主要在于其对猎物处理时间上的不同。

Experiment was conducted in laboratory to study the functional responses of the predator, Cyrtorhinus lividipennis that was reared on different rice varieties with the brown planthopper (BPH), Nilaparvata lugens, to BPH eggs. The results showed that the functional response of the predator fed on BPH on variety TN1, IR26, IR64 and Bing 97 34 were all highly significantly stronger than that of the predator fed on BPH on Bing 97 59, while no difference was found in functional responses of C. lividipennis reared on the former four varieties. The result of statistical analysis demonstrated that the handling time for a prey of the predator reared on Bing 97 59 was significantly longer than that of the predator reared on other four varieties, although there was no significant difference in instantaneous attack rate of C. lividipennis that were reared on various varieties, which indicated that the differences in functional responses among C. lividipennis reared on various varieties result from difference in handling time of the predator for a prey. The results in relation to IPM were discussed.
