【目的】 明确泰安地区忍冬害虫与天敌的群落数量特征，为忍冬害虫的防治及其天敌的保护利用提供科学理论依据。【方法】 于2017年和2018年对忍冬害虫及其天敌进行了系统抽样调查，基于害虫及其天敌的数量信息，对调查数据进行了群落主成分分析、典型相关分析和有序样本最优分割。【结果】 通过主成分分析，明确了不同时期起主要作用的害虫及其天敌种类，主要害虫有胡萝卜微管蚜Semiaphis heraclei、棉蚜Aphis gossypii、烟粉虱Bemisia tabaci、金银花尺蠖Heterolocha jinyinhuaphaga和金银花叶蜂Arge similes等，天敌主要有龟纹瓢虫Propylaea japonica、异色瓢虫Harmonia axyridis、三突伊氏蛛Ebrechtella tricuspidata、黄褐新园蛛Neoscone doenitzi、鞍形花蟹蛛Xysticus ephippiafus、食虫蝽类、捕食螨类和食蚜蝇类等。典型相关分析体现出主要害虫及其天敌类群之间存在显著相关性（P<0.01），食蚜蝇类、瓢虫类和草蛉类与蚜虫类（胡萝卜微管蚜）相关程度高；食虫蝽类与鳞翅目害虫（金银花尺蠖）和烟粉虱的相关程度高；蜘蛛类与植食性蝽类、叶蝉类、烟粉虱和鳞翅目害虫的相关程度高；捕食螨类与植食性蝽类、烟粉虱和鳞翅目害虫的相关程度高。有序样本最优分割表明，害虫与天敌群落时间格局均划分为4个时段，不同时段内害虫及其天敌的发生特点有明显差异，对各时段的害虫与相应的天敌进行了分析。【结论】 研究结果对忍冬害虫的防治和天敌的保护利用具有重要指导意义。

[Objectives]  The quantitative characteristics of the major insect pests and communities of their natural enemies in Lonicera japonica fields in Tai’an city were analyzed using multivariate statistics to provide information to assist the ecological regulation and environmentally-friendly control of insect pests and the conservation and utilization of their natural enemies. [Methods]  Insect pests and their natural enemies in L. japonica fields were investigated in 2017 and 2018 using systematical sampling and the composition of both communities analyzed with multivariate statistics. [Results]  The dominant insect pests and their natural enemies in different temporal periods were determined by principal component analysis. The main insect pests were Semiaphis heraclei, Aphis gossypii, Bemisia tabaci, Heterolocha jinyinhuaphaga and Arge similes, and their main natural enemies were Propylaea japonica, Harmonia axyridis, Ebrechtella tricuspidata, Neoscone doenitzi, Xysticus ephippiafus, plus predatory bugs, predatory mites and syrphids. Canonical correlation analysis showed that there were significant (P<0.01) correlations between the dominant insect pests and their natural enemies. The correlations of ladybirds, syrphids and lacewings to aphids (especially S. heraclei), predatory bugs to lepidopteran pests (especially H. jinyinhuaphaga) and B. tabaci, spiders to phytophagous bugs, leafhoppers, B. tabaci and lepidopteran pests, predatory mites to phytophagous bugs, B. tabaci and lepidopteran pests, were high. The temporal patterns of insect pests and their natural enemies were divided into four temporal periods in both years using optimal sorting. The occurrence patterns of insect pests and their natural enemies were different during the different temporal periods, and the abundance of insect pests and their corresponding natural enemies in different temporal periods, was analyzed. [Conclusion]  The results provide useful information for controlling insect pests and the conservation of their natural enemies in L. japonica fields.
