Abstract

Rapid and reliable diagnostic methods for arthropod pests and pathogens allow for a rational and efficient use of plant protection products. Traditional detection methods based on visual assessment of plant symptoms, isolation, culturing in selective media, and direct microscopic observation of pathogens are frequently laborious, time-consuming and require extensive knowledge of classical taxonomy. Molecular techniques are faster, more specific, sensitive, and accurate than traditional techniques. Plant viral and bacterial diagnostics have been traditionally based on serological methods, such as ELISA or Lateral Flow Devices. New molecular techniques (qPCR, digital PCR, microarray) have been developed, optimized and validated in the last years with different applications to pest and pathogen detection and identification. HTS technologies are having an enormous impact on biological sciences, allowing the determination of genome variation within a species or a population. The use of field techniques, such as LAMP and portable platforms, is a promising tool to early and quickly detect pests. One of the critical points of on-site detection consists in the use of simple and user-friendly nucleic acid extraction procedure, involving a low number of steps. The choice of the diagnostic technique depends on the balance between the reliability and the cost of the analysis.
