The greenhouse cucumber pests, Bemisia tabaci (Hemiptera: Aleyrodidae), Frankliniella occidentalis (Thysanoptera: Thripidae), and Tetranychus urticae (Acari: Tetranychidae), are major threats to the production of greenhouse cucumbers (Cucurbitaceae) in Lebanon. The development of insecticide resistance by these pests has prompted the use of alternative and sustainable pest management strategies. In this study, we used integrated pest management strategies, including the release of the biological control agents, Amblyseius swirskii Athias-Henriot (Mesostigmata: Phytoseiidae) and Phytoseiulus persimilis Athias-Henriot (Mesostigmata: Phytoseiidae), to control whitefly, thrips, and two-spotted spider mite populations on greenhouse cucumber plants in two commercial production sites (sites A and B). We also compared the efficacy of pest population suppression using the integrated pest management strategy with that of chemical pest control. Our results show that biological control effectively maintains the cucumber pest populations below the economic threshold when coupled with additional integrated pest management measures. In addition, we show that biological control agents were equally or more effective in pest population suppression compared to eight and 12 insecticidal and acaricidal sprays performed in the control greenhouses at sites A and B, respectively. Altogether, our results show the efficacy of adopting integrated pest management and biological control for pest population suppression in greenhouse cucumber production under Mediterranean environmental conditions.

温室黄瓜害虫烟粉虱（半翅目：粉虱科）、西方富兰克林（缨翅目：蓟马科）和叶螨科（螨科：叶螨科）是黎巴嫩温室黄瓜（葫芦科）生产的主要威胁。这些害虫产生的杀虫剂抗性促使人们采用替代性和可持续的害虫管理策略。在这项研究中，我们使用了综合害虫管理策略，包括释放生物防治剂Amblyseius swirskii Athias-Henriot（Mesostigmata：Phytoseiidae）和Phytoseiulus persimilisAthias-Henriot (Mesostigmata: Phytoseiidae)，用于控制两个商业生产地点（地点 A 和 B）的温室黄瓜植物上的粉虱、蓟马和二斑叶螨种群。我们还比较了使用害虫综合管理策略和化学害虫防治策略抑制害虫种群的效果。我们的结果表明，结合额外的综合害虫管理措施，生物防治有效地将黄瓜害虫种群保持在经济阈值以下。此外，我们表明，与分别在 A 点和 B 点的对照温室中进行的 8 次和 12 次杀虫和杀螨喷剂相比，生物防治剂在抑制害虫种群方面的效果相同或更有效。共，
