It Flower Thrips Frankliniella occidentalis (Pergande) have been recorded causes direct feeding damage to a wide variety of for the frst tme from India. F. occidentalis was collected on the leaves of Erythrina indica from Ooty in the Nilgiris, the Western Ghats, agricultural and hortcultural crops and is an important southern India, whereas C. punctpennis was collected from yellow vector of tospoviruses (family Tospoviridae, genus pan traps laid at Great Nicobar, India.

Out of these, F. occidentalis is responsible This along with other plantng materials carried by tourists and for the transmission of as many as fve species of farmers could aid in the dispersal of F. occidentalis to the temperate tospoviruses (Chrysanthemum Stem Necrosis Virus, regions of northern and southern India, where it is likely to thrive in the congenial climatc conditons prevalent there.

The genus Caliothrips, erected by Daniel in 1904, comprises 25 described species worldwide (Thripswiki - referred on 7 December 2017), with fve species known from India (Rachana & Varatharajan 2017). Hood in 1912 described the species punctpennis under the genus Heliothrips. Caliothrips is closely related to many Panchaetothripinae genera, but can be recognized by the following characters: parallel cheeks, one segmented tarsi, antennal segments III and IV with forked sense cones, absence of a complete comb of microtrichia on © R.R. Rachana hind margin of tergite VIII (Wilson 1975). In additon, Image 1. Female Caliothrips punctpennis members of the genus Caliothrips are recognisable by the form of sculpture on head and pronotum, with prominent markings within the retculatons and the presence of a coiled apodeme within each hind coxa.
