Abstract
Experiment was
carried out at the farmers field near the Faculty of Agriculture, Wadura,
Kashmir, India during 2021-22 under free choice conditions to study seasonal
incidence of cereal leaf beetle (Oulema melanopus) infesting Rabi Oats (Avena
sativa L.) in North Kashmir. The results obtained during investigation revealed
that, both adults and grubs of O. melanopus appeared on oats from 10th standard week of 2021 and attained
peak (21/m-2) in 12th standard week. During 2022 peak of
the pest was observed in 11th standard week, while appearing from 9th
standard week. However, the larval population commenced from 14th
standard week with its peak (334/m-2) in 16th standard
week. In year 2022, Adult population of O. melanopus appeared on oats
from 9th standard week of 2022 and attained peak (23/m-2)
in 11th standard week. While, the larval population commenced from
13th standard week with its peak (336/m-2) in 17th
standard week. Later on, the pest population declined gradually towards
the maturity of crop. Activity of pest has been observed in months of
April-June where temperatures are congenial for multiplication of the pest,
while the period before and after were low and high, respectively. The
variation in degree of damage through this pest might be attributed because of
change in weather factors responsible for overall climate change.
