| 通过对湖南晚稻常规稻、杂交稻和超级杂交稻田的拟水狼蛛和褐飞虱进行调查，运用Taylor幂法和Iwao的回归分析法对拟水狼蛛、褐飞虱若虫及成虫的空间分布型拟合，两种方法研究结果表明:褐飞虱若虫、短翅型成虫和长翅型成虫在3个水稻品种上都为聚集分布，拟水狼蛛为随机分布。采用 Holling Ⅱ型拟合拟水狼蛛对褐飞虱若虫、短翅型成虫和长翅型成虫的捕食功能，结果表明拟水狼蛛对三者捕食功能大小顺序为若虫＞长翅雄虫＞长翅雌虫＞短翅雄虫＞短翅雌虫，日最大捕食量分别为64.4、37.4、42.8、28.1头和35.1头。 |

| Through massive screening of conventional rice, hybird race and super hybrid rice in Hunan province, the spatial distribution of brown planthopper (BPH) Nilaparvata lugens (Stl) and Pirata subpiraticus were studied by Taylor power and Iwao’s regression equation. The results showed that the spatial distribution of BPH nymphs belonged to aggregative distribution on the three rice plants, and the same results were observed in the macropterous and brachypterous adults of BPH. However, the spatial distribution of P. subpiraticus was stochastic distribution. Furthermore, the mathematical model of predation of P. subpiraticus on BPH was established with Holling II in this paper. The results showed that the predacious capacity of P. subpiraticus on BPH from high to low was as followed: nymph, macropterous male, macropterous female, brachypterous male and brachypterous female, and their maximum daily predacious capacities were 64.4, 37.4, 42.8, 28.1 and 35.1, respectively. |
