| Abstract (English): |
[Objectives] To study the effects of chlorantraniliproleon on rice planthoppers and their parasitic natural enemies in paddy fields, together with changes in arthropod community parameters, in order to provide a scientific basis for the rational use of chlorantraniliprole. [Methods] Four rice fields were treated with chlorantraniliprole and four control rice fields were selected in Suizhou city and Xiaogan city, Hubei province. Arthropods were collected using the suction method and their dominance, population density, and the correlation between rice planthopper abundance and that of their parasitic natural enemies, was compared between treated and control rice fields. [Results] In most cases, there was no significant difference in the dominance and population density of rice planthoppers and that of their parasitic natural enemies between treated and control fields in 2011 and 2012. There was, however, a significant positive correlation between the number of rice planthoppers and that of their parasitic natural enemies in control and treatment fields in Xiaogan (2011: control field, R2=0.249, P=0.007; treated field, R2=0.462, P<0.001;2012: control field, R2=0.189, P=0.021; treated field, R2=0.212, P<0.014). However, no significant correlation between rice planthopper abundance and that of their parasitic natural enemies was found in the two treatment fields in Suizhou over these two growing seasons. [Conclusion] The application of chloramphetamine to rice fields did not affect the ecological function of parasitic natural enemies of the rice planthopper, and did not adversely affect non-target pests or parasitic natural enemies of the rice planthopper.

【目的】 研究稻田施用氯虫苯甲酰胺后对非目标害虫--稻飞虱及其寄生类天敌的影响, 为氯 虫苯甲酰胺的合理使用提供参考。【方法】 2011 和2012 年在湖北省随州市和孝感市, 选取施用和不施用 氯虫苯甲酰胺的稻田各4 块, 采用吸虫法采集稻田节肢动物, 并比较了施用和不施用氯虫苯甲酰胺药剂稻 飞虱及其寄生类天敌优势度、种群密度以及相互关联程度的差异。【结果】 2011 年和2012 年, 在湖北省 随州市和孝感市稻田稻飞虱及其寄生类天敌的优势度和种群密度在对照田和施药田之间均没有显著差异。 在孝感两年试验中, 对照与施药田中的稻飞虱与寄生类天敌种群数量均呈显著正相关（2011：对照田, R2=0.249, P=0.007, 施药田, R2=0.462, P<0.001;2012：对照田, R2=0.189, P=0.021, 施药田, R2=0.212, P<0.014）。而随州在连续2 年的观测期内, 无论对照还是施药田中的稻飞虱与其主要寄生性天敌的种群数 量均不存在显著的相关关系。【结论】 在稻田施用氯虫苯甲酰胺未影响寄生天敌发挥其生态功能, 且不会 对非靶标害虫稻飞虱及稻飞虱寄生类天敌种群产生不利影响.
