Seasonal Incidence of mustard flea beetle, Phyllotreta cruciferae on Brassica species in relation to weather parameters at different dates of sowing

Shweta Patel, Chandra PAL Singh and Sunil Kumar Yadav

The present field experiment was carried out to study the incidence of flea beetle on Brassica species in different dates of sowing at Norman E. Borlaug Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar, India during Rabi 2015-16 and 2016-17. Eight Brassica species including B. rapa cv. BSH-1and YST-151, B. alba, B. carinata, B. nigra, E. sativa cv. T-27, B. juncea cv. Varuna and B. napus cv. GSC-6 were sown on five dates of sowing starting from October 3 to December 3, 2015 and 2016 at fifteen days interval. The results showed that E. sativa harboured highest population of P. cruciferae (5.79 and 19.2 bettles/ m2) while it was lower on B. carinata (2.08 and 6.1 bettles/ m2) during consecutively for two years, 2015-16 and 2016-17. the population of flea beetle recorded on different brassica species in present study different significantly with respect to different dates of sowing in both the years. regarding the date of sowing, overall mean population of P. cruciferae was found maximum in first, second and third sowing date of sowing while minimum in fourth and fifth date of sowing during 2015-16. however, the flea beetle population was found higher in fourth and fifth date of sowing during 2016-17.
