A modified Robinson light trap with a 120-watt M.V. lamp was operated from 1800 to 2400 h. Green leafhopper (GLH) catch and tungro (RTV) infection were recorded daily. GLH field infestation was recorded 30 d after transplanting (DT) and RTV infection 45 DT on TKM9 in sornavasi, CO 43 in Samba (Jul-Aug to Dec-Jan), and ADT 36 in Navarai (Dec-Jan to Apr-May).

Level of RTV infection followed a similar pattern, peaking in Jul, and gradually declining from Aug to Oct
