South American tomato leaf miner Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is responsible for significant biological invasions of tomato crops, perturbing global food production. The larvae feed within leaves, stems, and fruits, creating characteristic mines that reduce photosynthetic capacity by causing leaf necrosis and rendering fruits unmarketable. Synthetic pesticide applications used to suppress pest populations have detrimental impacts on the environment and human health and incur high production costs to farmers. These prevailing situations highlight the urgency of sustainable pest management practices. AI-driven pest monitoring systems assist farmers by enabling early pest detection and predicting expected pest outbreaks before their devastating attacks on crops. These data-driven insights facilitate farmers in implementing proactive pest control strategies, permitting reduced but impactful pesticide use through tracking pest population levels in the field. To develop smart pest monitoring systems to control T. absoluta outbreaks in tomato crops in greenhouse settings, this study highlights the use of AI-based pest detection and population prediction models to detect pest incidences and predict outbreaks in advance. A real-time image dataset was collected in greenhouse conditions to train various object detection models such as YOLOv10, YOLOv11, and YOLOv26 for the early detection of T. absoluta. The YOLOv26 model outperformed its counterpart approaches in terms of pest detection accuracy and inference speed by delivering 98.4% (mAP50) and 0.053 seconds, respectively. For early prediction of pest outbreaks, abiotic parameter data were collected through IoT sensors alongside pest biological data to generate early forecasts. Feature engineering and feature selection approaches were used for data preparation to model pest population dynamics. Various ML and ensemble learning approaches were implemented to model pest dynamics in relation to different meteorological parameters, where a blended ensemble learning technique resulted in the best prediction performance by delivering 4.99517, 62.415492, and 7.900348 values for MAE, MSE, and RMSE metrics, respectively.

To develop smart pest monitoring systems to control T. absoluta populations in tomato crops in greenhouse settings, this study highlights the use of AI-based pest detection and population prediction models to detect pest instances and forecast populations in advance. A real-time image dataset was collected in greenhouse conditions to train various object detection models such as YOLOv10, YOLOv11, and YOLOv26 for the early detection of T. absoluta. A dataset of 317 trap images was deployed to evaluate the detection capabilities of pest detection models. The YOLOv26s model outperformed its counterpart approaches in terms of pest detection accuracy by delivering 92.4% (mAP₅₀), and YOLOv26n delivered an inference speed of 0.064 s on test data. For early prediction of the male moth population, abiotic parameter data were collected through IoT sensors alongside pest biological data to generate early forecasts. Feature engineering and feature selection approaches were used for data preparation to model male moth population dynamics. Machine learning approaches and a hybrid linear-tree stacking framework were implemented to model pest dynamics in relation to different meteorological parameters. The hybrid stacking model resulted in an NRMSE value of 0.31 when predicting the one-week-ahead population of male T. absoluta.
