哥伦比亚是世界上最大的咖啡（Coffea arabica L. (Rubiaceae)）生产国之一。咖啡果蛀虫（CBB），又称咖啡果蛀虫（Hypothenemus hampei）（鞘翅目：瓢虫科：蠹蛾科）是咖啡的主要害虫。这种昆虫是通过综合虫害管理计划控制的，包括文化、生物和化学控制策略。尽管研究寻求CBB引诱剂和驱避剂，但这些潜在的管理工具尚未成功纳入控制计划。本研究提出利用植物功能多样性对CBB进行管理，并选择了一些与咖啡和杂草相关的植物。通过嗅觉测定确定了这些植物对CBB的偏好，并鉴定了它们释放的挥发性化合物。在田间条件下进行了CBB偏好试验。这些试验确定了CBB对咖啡浆果的嗅觉偏好，咖啡浆果中有植物材料，如豆科植物Crotalaria micans Link，马鞭草科植物Lantana camara L.（马鞭草科），烟草(Nicotiana tabacum L.（茄科），普通蒿L.，金盏花L.，甜菊糖（Bertoni） Bertoni和Emilia sonchifolia （L.）。直流。（四种菊科）。在实验室条件下，用嗅觉测定法测定了烟草N., camara L.和officinalis对CBB具有驱避作用，而sonchifolia对CBB具有引诱作用。田间对照试验证实了烟草和棉蚜对CBB的驱避作用；两者都释放挥发性倍半萜。选定的候选引诱剂包括sonchifolia植物，用于在实验室中显示吸引力。讨论了这些植物在咖啡种植园农业生态管理中的潜在应用。
Colombia is one of the world's largest producers of coffee [Coffea arabica L. (Rubiaceae)]. The coffee berry borer (CBB), Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the main pest of coffee. This insect is controlled through an integrated pest management program that includes cultural, biological, and chemical control strategies. Despite research seeking CBB attractants and repellents, these potential management tools have not been successfully incorporated into control programs. This work proposes the use of plant functional diversity for CBB management, for which a number of plants related to coffee and weeds were selected. CBB preference to these plants was determined by olfactometry and volatile compounds emitted by them were identified. Field trials were performed to test CBB preference under field conditions. These trials determined the olfactory preference of CBB to coffee berries accompanied by material of the plants Crotalaria micans Link (Fabaceae), Lantana camara L. (Verbenaceae), Nicotiana tabacum L. (Solanaceae), Artemisia vulgaris L., Calendula officinalis L., Stevia rebaudiana (Bertoni) Bertoni, and Emilia sonchifolia (L.) DC. (all four Asteraceae). Under laboratory conditions N. tabacum, L. camara, and C. officinalis were identified as repellents for CBB in olfactometer assays, whereas E. sonchifolia functioned as attractant. Controlled field trials corroborated CBB repellency of N. tabacum and L. camara; both release volatile sesquiterpenes. Selected candidate attractants included E. sonchifolia plants, for showing attraction in the laboratory. The potential use of these plants in agroecological management of coffee plantations is discussed.
