Associations between the South American tomato pinworm, (Meyrick) (Lepidoptera: Gelechiidae), and its native parasitoids need to be updated to increase the implementation of pest control strategies. In this study, -infested tomato plants were collected from three regions in Kenya. The emerged parasitoids were identified, and their abundance was correlated with agroecological parameters, . cropping systems, and the abundance of the predator Reuter (Hemiptera: Miridae). The study further conducted a habitat suitability prediction for the identified parasitoids. Two parasitoid species, (Szépligeti) (Hymenoptera: Braconidae) and sp. near (Ashmead) (Hymenoptera: Eulophidae) emerged from immature stages, with parasitism rates ranging from 0 to 21% and 0 to 17% respectively. Insecticide application and open field cropping negatively influenced the parasitism by sp. nr . Low occurrence of positively affected parasitism. The predicted occurrence of parasitoid species indicated vast suitable areas for in sub-Saharan Africa, Australia, and South America. Low suitability was observed for sp. nr in Africa. Therefore, native parasitoids, especially could be considered for implementation as a biocontrol agent in the Integrated Pest Management program of .
南美番茄潜叶蛾（Meyrick）（鳞翅目：麦蛾科）与其本地寄生蜂之间的关联需要更新，以加强害虫防治策略的实施。在本研究中，从肯尼亚的三个地区收集了受南美番茄潜叶蛾侵害的番茄植株。对羽化出的寄生蜂进行了鉴定，并将其丰度与农业生态参数、种植系统以及捕食性昆虫黑肩绿盲蝽（Reuter）（半翅目：盲蝽科）的丰度进行了关联分析。该研究还对已鉴定的寄生蜂进行了栖息地适宜性预测。从南美番茄潜叶蛾未成熟阶段羽化出了两种寄生蜂，即扁股小蜂（Szépligeti）（膜翅目：茧蜂科）和近丽突小蜂（Ashmead）（膜翅目：釉小蜂科），寄生率分别为0%至21%和0%至17%。施用杀虫剂和露地种植对近丽突小蜂的寄生有负面影响。黑肩绿盲蝽的低发生率对扁股小蜂的寄生有积极影响。预测的寄生蜂物种分布表明，在撒哈拉以南非洲、澳大利亚和南美洲有大片适合扁股小蜂生存的区域。在非洲，近丽突小蜂的适宜性较低。因此，在南美番茄潜叶蛾的综合害虫管理计划中，可以考虑将本地寄生蜂，特别是扁股小蜂作为生物防治剂加以应用。
