The shoot and fruit borer, Leucinodes orbonalis has a countrywide distribution and has been categorized as the most destructive and most serious pest causing huge losses in brinjal. In the present study total of 21 populations of L. orbonalis collected mainly from Karnataka and also from Andhra Pradesh, New Delhi and Uttar Pradesh were molecularly characterized. The sequencing resulted in 600-636 bp product of CO I gene and amino acid composition of nucleotide, which varied from 195-206 in different populations. The certain amino acids were either present nor absent in different populations indicating their diversity. The pair-wise genetic distance of L. orbonalis populations ranged from 0.00 to 0.051, suggesting that there was variation in population of L. orbonalis from different locations. The highest genetic distance was observed from the population of Udupi district i.e. 0.051, followed by Koppal district is 0.047, Raichur, Chitoor, Vijayapura, Bagalkot and Guntur population having genetic distance of about 0.039 and other populations have different genetic distances which are related to each other. Therefore, it is inferred that there was no significant molecular diversity within L. orbonalis of different geographical locations of India with respect to COI but there is difference in the amino acid composition and genetic distance among the populations.
