Studies were conducted on the incidence of maize stem borer, Chilo partellus (Swinhoe) at DARS, Budgam, SKUAST-K during the Kharif season, 2015. The incidence of the insect was assessed in maize variety C-15 sown in April 2015. The lowest leaf infestation recorded during entire crop season was first observed in 18th standard week (SW) (1st week of May) with leaf infestation of 4.00 per cent while the highest infestation was recorded in 28th SW (2nd week of July) as 48.50 per cent. The lowest dead heart occurrence of 6.50 per cent was recorded in 20th SW (3rd week of May) and the highest was 37.00 per cent in 27th SW (1st week of July). Similarly the adult moth catch was found lowest in 17th SW (4th week of April) with 5.00 moths/trap and highest in 24th SW (2nd week of June) with 20.00 moths/trap. A positive and significant correlation was found between leaf infestation, dead heart and moth catch with maximum temperature, minimum temperature, maximum relative humidity, however, correlation was positive but non-significant with rainfall while a negative and non-significant correlation with sunshine and minimum relative humidity was observed. The adult moth catch was found to be non-significant but positively correlated with minimum relative humidity.
