New Record of Western Flower Thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in South India

摘要: A necrosis disease of chrysanthemum caused by Tomato spotted wilt virus was reported in recent years Tamil Nadu, a southern state India. Whether Frankliniella occidentalis, the vector TSWV is associated with looked into analyzing thrips populations these regions for morphometric and mtCOI gene sequences. The morphological key characters studied fitted very well description given F. occidentalis. PCR amplified 358 bp fragment analyzed 24 individual from 12 locations Nadu. consensus sequences revealed 92-100 % identity selected occidentalis database. Of eight analyzed, two them 100 many However, one populations, FOTN6 distinct exhibited only 92 all compared. Totally there were 48 polymorphic sites out nucleotides compared, which more than 65 resulted changes amino acids. confirmation presence India paramount importance considering its role as active tospoviruses present important ornamental high valued crops.
