Abstract: Aleurocanthus spiniferus (Quaintance) (Hemiptera: Aleyrodidae) has rapidly spread, mainly in the central and eastern Mediterranean coastal area, infesting various new host plants alongside known ones. This invasive species poses a significant threat to agricultural ecosystems, necessitating urgent action to monitor and control outbreaks in previously pest-free areas. While entomological and morphological recognitions are crucial for initial detection, challenges often arise in quickly identifying different developmental stages or genus-level distinctions, particularly in surveys conducted by personnel with limited entomological skills. Due to these challenges, a qPCR probe protocol was developed to enhance the diagnostic capacity of laboratories responsible for the territorial control of pests. This biomolecular tool integrates morphological surveys, enabling prompt and reliable proof of A. spiniferus presence in free areas, delimited territories, or during phytosanitary import inspections. The protocol’s high analytical specificity, inclusivity, and exclusivity ensure accurate identification of A. spiniferus, while its low limit of detection and high repeatability and reproducibility reinforce its utility as a standardized diagnostic method. By facilitating prompt and targeted control efforts, this innovative approach strengthens the resilience of agricultural systems against the widespread threat of A. spiniferus infestations.
