The mitochondrial DNA sequences of Cytochrome Oxidase subunit – I gene of Aphidiine parasitoids (Hymenoptera: Braconidae: Aphidiinae) were subjected to phylogenetic analysis to understand the intergeneric and interspecific variations and the role of geographical isolation on speciation; using CLUSTAL W in MEGA version 5.1. This analysis includes sixty two species belonging to eleven genera from sixteen countries viz., Algeria, Canada, Chile, China, Czech Republic, Iran, France, Greece, Libya, Montenegro, Poland, Serbia, Slovenia, Spitsbergen (Svalbard), Switzerland, USA. The pair-wise genetic distances were calculated and phylograms were constructed using Maximum Likelihood, Maximum Parsimony, and Neighbor-Joining methods. This analysis revealed phylogenetic relationships and the role of geographical isolation on speciation.
