Scanning electron microscope comparison of Diorhabda elongata ecotypes

Diorhabda elongata (Chrysomelidae), commonly known for effective biocontrol of Tamarix spp., is a complex of ecotypes, possibly consisting of several species. Based on geographic origin and morphological characteristics, various experts have thus proposed reclassification of members in this species group to D. elongata, D. carinata, D. sublineata, D. carinulata, and D. meridionalis. Scanning electron micrograph images of aedeagi were compared to distinguish adequate differences between ecotypes of D. elongata.
