| dna barcoding and elucidation of cryptic aphid species (hemiptera: aphididae) in india. | rapid, precise and timely identification of invasive pest insects such as aphids is important and a challenge worldwide due to their complex life cycles, parthenogenetic reproduction, sex and colour morphs. in this respect, dna barcoding employing a 658 bp fragment of 5′ region of the mitochondrial cytochrome oxidase i (co-i) gene is an effective tool in addressing the above. in the present study, we employed co-i for discriminating 142 individuals representing 32 species of aphids from india. s ... | 2013 | 23680306 |
