摘　　要：为协调褐飞虱Nilaparvata lugens(Stl)的化学防治和生物防治提供参考,本研究采用稻茎浸渍法研究了氯虫苯甲酰胺对黑肩绿盲蝽Cyrtorhinus lividipennis(Reuter)捕食褐飞虱功能反应的影响。结果表明:在氯虫苯甲酰胺的推荐剂量下,黑肩绿盲蝽功能反应模型的结构没有改变,但影响到了模型的各项参数。在推荐剂量下,氯虫苯甲酰胺可降低黑肩绿盲蝽的瞬时攻击率(a');药剂处理后黑肩绿盲蝽若虫对褐飞虱卵、1龄若虫和2龄若虫的处理时间(Th)比对照分别增加163.03%,104.21%和95.11%,而黑肩绿盲蝽成虫对它们的处理时间则分别增加81.97%,102.45%和99.52%;药剂处理后黑肩绿盲蝽日最大捕食量(Na*)降低,其寻找效应(S)也减弱。研究表明氯虫苯甲酰胺对黑肩绿盲蝽捕食作用存在着不良影响。Aimed to provide a reference to the chemical and biological control of Nilaparvata lugens （Stal）, the effects of the chlorantraniliprole on the functional response of Cyrtorhinus lividipennis （Reuter） preying on N. lugens were studied with rice stem dipping method. The results revealed that the functional response models of C. lividipennis preying on N. lugens all conformed to Holling＇ s type 11 curve after C. lividipennis were pretreated with the labeled dose of chlorantraniliprole （LDC）. However, the parameters in the models had some changes. The instantaneous attacking rate （a＇） of C. lividipennis pretreated with the insecticide declined. The handling time （Th） on eggs, 1st instar nymphs and 2nd instar nymphs of N. lugens by C. lividipennis nymphs pretreated with LDC was extended by 163.03% , 104.21% and 95.11% , and 81.97%, 102.45% and 99.52% by C. lividipennis adults pretreated with LDC, respectively. The maximal predatory capacities （Na ＊ ） of C. lividipennis pretreated with the insecticide reduced. The searching efficiency （S） of C. lividipennis pretreated with LDC reduced as compared to that of untreated predators. These results suggest that chlorantraniliprole at labeled dose has harmful influence on the predation of C. lividipennis.
