| 田间应用功能植物的保护型生物防治技术，有助于实现天敌昆虫释放后对种群定殖与可持续控害的增效作用，是农业可持续发展的研究热点。为了探究北方冬季温室内功能植物协同捕食性天敌对害虫的控制作用，本研究以蜜源植物金盏菊Calendula offinalis和捕食性天敌东亚小花蝽Orius sauteri为对象，以不含金盏菊为对照，系统研究了金盏菊对东亚小花蝽成虫寿命和定殖的影响，以及对草莓上重要害虫蚜虫和叶螨的防控效果。结果发现，温室种植金盏菊显著增加了东亚小花蝽雌成虫的存活率和寿命，东亚小花蝽雌成虫的寿命达到9.49 d，较对照（6.18 d）延长了53.6%。金盏菊存在显著增加了释放东亚小花蝽后的第2~4周的种群数量，显著降低了草莓植株上棉蚜和叶螨的密度，表明金盏菊通过支持东亚小花蝽存活与种群定殖，增效草莓害虫防控。本研究不仅支持了蜜源植物增效天敌和控制害虫的生态作用，还为北方冬季温室草莓的害虫生物防治方式多元化应用与推广提供实践指导。 |

| Conversation biological control based on the utilization of functional plants can realize the synergistic colonization and sustainable pest control of natural enemies after the release of natural enemies, which is a research hotspot of agricultural sustainable development. To explore the effect of functional plants cooperating with predatory natural enemies to prevent and control pests in greenhouse during winter, this study systematically evaluated the effects of nectar plant, Calendula officinalis on the longevity and colonization of Orius sauteri. Without C. officinalis as the control, the study also compared the control effects on aphids and herbivorous mites on strawberries in greenhouse in winter. Results showed that compared with the control without C. officinalis, the existence of C. officinalis significantly increased the survival rate and average longevity of the female adult of O. sauteri, the lifespan of female adult reached 9.49 days in treatment, which was 53.6% longer than the lifespan in the control (6.18 days). The presence of C. officinalis significantly increased the population number in the second to fourth week after the release of O. sauteri, and significantly reduced the density of aphids and herbivorous mites on strawberry plants, indicating that C. officinalis enhanced strawberry pest control by supporting the survival and population colonization of O. sauteri. This study not only supports the ecological role of nectar plants in enhancing natural enemies and controlling pests, but also provides practical guidance for the diversified application and popularization of biological pest control methods for strawberries in winter greenhouses in northern China. |
