Description:

Exorista sorbillans, the uzi fly, is a serious tachinid pest of silkworm and is present in all silk producing areas of Asia. Assuming that E.sorbillans was accidentally transported from West Bengal to southern states of India, its population genetic structure was studied using 13 ISSR, 3 RAPD, two sets of universal primers and two sets of primers designed from a lepidopteran repeat sequence. Statistical analyses of DNA markers revealed significant genetic variability between the E. sorbillans populations from 4 different geographic locations (within 400 km of one another) in the southern states and the one from West Bengal (Murshidabad). Multivariate and discriminant function analyses indicate that the E. sorbillans from south India has diverged from the original gene pool of West Bengal and is suitable for studying the microevolution of adaptation to the conditions prevailing in the different cocoon producing areas in India. Abbreviations used. GP = geographic population; ISSR = Inter Simple Sequence Repeat; PCR = Polymerase Chain Reaction; RAPD = Random Amplified Polymorphic DNA; SPSS = Statistical Package for Social Sciences; UBC = University of British Columbia; UNIV = Universal.
