The present investigation was made to study the field life-tables and key mortality factors of Plutella xylostella infesting sole and onion intercropped cabbage. P. xylostella passed through 3 and 2 generations on sole and onion intercropped cabbage, respectively during rainy season 2011.On sole cabbage the highest mortality of early and late instar larvae of P. xylostella in first, second and third generations during rainy season 2011 was observed to be 33.90, 37.62 and 32.73 per cent due to Cotesia vestalis followed by unknown causes (10.10, 13.52 and 0.00 per cent).
