摘　　要：【目的】通过室内测定稻虱缨小蜂Anagrus nilaparvatae对水稻单一挥发物和混合挥发物的行为反应,研究水稻挥发物对稻虱缨小蜂的引诱效果,为进一步探索信息化合物在害虫防治中的应用提供理论依据。【方法】利用Y型嗅觉仪测定醇类、酮类、酚类、醛类、烯类和吲哚类等12种水稻单一挥发物对稻虱缨小蜂的引诱效果,利用引诱效果显著的单一化合物进行特定浓度的混配,进而测定稻虱缨小蜂对混合水稻挥发物的行为反应。【结果】单一挥发物中,香叶基丙酮(0.1 mg/L)、2-庚醇(1 mg/L)、正壬醇(10 mg/L)和β-石竹烯(0.01 mg/L)对稻虱缨小蜂有显著的引诱效果;对具有引诱效果的单一挥发物进行混配发现,No.1,No.3,No.4和No.10这4种组合的混合物对稻虱缨小蜂的行为有显著的影响。【结论】水稻挥发物能够影响稻虱缨小蜂的行为反应,但其引诱效果受挥发物种类、浓度和混配比例等多种因素的影响。[Objectives] To evaluate the attractiveness of single, and mixtures of different, rice plant volatiles to Anagrus nilaparvatae and thereby provide a theoretical basis for further exploring the application of semiochemical-based attractants as part of the integrated management of this pest. [Methods] The behavioral responses of A. nilaparvatae to 12 rice plant volatiles, including alcohols, ketones, phenols, aldehydes, olefins and indoles, were tested in a Y-tube olfactometer. Several mixtures of behaviorally-active compounds were also tested. [Results] A. nilaparvatae was significantly attracted by 0.1 mg/L of geranyl acetone, 1 mg/L of 2-heptanol, 10 mg/L of 1-nonanol and 0.01 mg/L of β-caryophyllene. Mixture No.1, No.3, No.4 and No.10 were also significantly attractive to A. nilaparvatae. [Conclusion] Rice plant volatiles can significantly affect the behavior of A. nilaparvatae, and their attractiveness varies with compound, concentration and the ratio at which different volatiles are mixed.
