Different species of rapeseed-mustard including B. rapa cv. BSH-1 and YST-151, B. alba, B. carinata, B. nigra, E. sativa, B. juncea and B. napus were sown on five dates of sowing starting from October 3 to December 3, 2016 at fifteen days interval. The results showed that B. juncea harboured highest population of Athalia lugens proxima while minimum was on E. sativa. There was no consistency in damage of A. lugens to Brassica species at different dates of sowings.
