摘  要：
【目的】为明确东亚小花蝽Orius sauteri对草地贪夜蛾Spodoptera frugiperda幼虫的捕食能力及生物防治潜能。【方法】在室内条件下测定了东亚小花蝽3, 4和5龄若虫以及雌成虫对不同密度的草地贪夜蛾1龄幼虫的捕食能力;采用Holling II模型拟合计算东亚小花蝽对草地贪夜蛾的捕食功能反应和寻找效应。【结果】东亚小花蝽3, 4和5龄若虫以及雌成虫对草地贪夜蛾1龄幼虫的捕食功能反应均符合Holling II模型,东亚小花蝽雌成虫对草地贪夜蛾1龄幼虫的日捕食能力(a′/T_h)最强,为15.85头;最大理论捕食量(1/T_h)最大,为23.26头/d;处理单头猎物所需时间最短,为0.043 d;东亚小花蝽4龄若虫对草地贪夜蛾1龄幼虫的日捕食能力(a′/T_h)最低,仅为10.85头。东亚小花蝽对草地贪夜蛾1龄幼虫的捕食量与猎物密度呈正相关,而寻找效应与猎物密度呈负相关。【结论】研究表明东亚小花蝽对草地贪夜蛾1龄幼虫具有较好的捕食能力。这些研究结果为正确评价东亚小花蝽对草地贪夜幼虫的生防潜能提供了理论依据。

摘  要：
【Aim】 To evaluate the predation capability and biological control potential of the minute pirate bug, Orius sauteri to the fall armyworm, Spodoptera frugiperda. 【Methods】 The predatory capacity of the 3 rd, 4 th and 5 th instar nymphs and female adults of O. sauteri on the 1 st instar larvae of S. frugiperda were assayed in the laboratory. The Holling-type II model was used to fit the functional response and searching efficiency of O. sauteri on the 1 st instar larvae of S. frugiperda. 【Results】 The predation of the 3 rd, 4 th and 5 th instar nymphs and female adults of O. sauteri on the 1 st instar larvae of S. frugiperda followed a Holling-type II functional response. The female adults of O. sauteri preying on the 1 st instar larvae of S. frugiperda had the highest predation rate, with the a′/T_h value of 15.85 individuals per day, 1/T_h value of 23.26 individuals per day and handling time of 0.043 d, respectively. The 4 th instar nymphs of O. sauteri preying on the 1 st instar larvae of S. frugiperda had the lowest predation rate, with the a′/T_h value of 10.85 individuals per day. The predation amount of O. sauteri to the 1 st instar larvae of S.frugiperda was positively correlated with the prey density, while its searching efficiency was negatively correlated with the prey density. 【Conclusion】 The results indicate that O. sauteri has a good control potential on S. frugiperda. These results provide a theoretical basis for evaluating the potential of O. sauteri as a biological control for S. frugiperda.
