Fifteen varieties/germplasm accessions of rapeseed mustard were evaluated for ovipositional preference by mustard sawfly. The experiment was conducted in earthen pots, under nylon net during two consecutive years 2004–05 and 2005–06. RK 2010, RK 2015, Kanti, Urvasi, RK 20ll and RK 2004 were less preferred by gravid female sawfly to lay eggs on them, while RK 2006, Rohini, RK 2013, Basanti, Kesari and Varuna were most preferred for egg laying. Reduced egg hatchability was observed on the variety RK 2011, RK 2010, RK 2004, Kanti, RK 2014, RK 2015, PR 4001 and Urvasi.
