This study investigates the genetic variation and taxonomic delineation of three key organisms: Spodoptera litura (a major agricultural pest), Hiptage benghalensis (an invasive plant species), and parasitoids in the genus Psyttalia (biocontrol agents). Using mitochondrial COI and nuclear ITS markers, we analyzed populations collected from multiple biogeographical zones in Southeast Asia. Phylogenetic trees were constructed to assess intraspecific and interspecific divergence, revealing cryptic lineages within S. litura and significant genetic structuring in H. benghalensis populations, likely due to multiple introductions. Psyttalia species were found to exhibit host-associated genetic variation, suggesting the presence of unrecognized taxa. These findings underscore the importance of integrating molecular tools into classical taxonomy to enhance the accuracy of species identification and to support the development of effective management strategies for invasive species and biological control programs. Our results provide a foundation for future ecological and applied research across tropical agroecosystems.
