Abstract


A roving survey was undertaken during April-May 2016 in various date palm growing villages of Kachchh region covering 20 villages and 83 orchards when the fruits were of in Habbab stage or beginning of Khalal stage. During the survey, it was observed that both immature and mature fruits were distorted in several orchards. The fruits showed scarring, blistering symptoms with a constriction giving an ‘8’ (eight) shape to the fruits. Observations on extent of fruit deformation (%) per bunch in different villages were recorded  which was later identified as Frakliniella schultzei.  Hence presence of F. schultzei on date palm and its economic damage is probably the first report from India.
