Influence of weather parameters on incidence of cardamom shoot and capsule borer (Conogethes punctiferalis Guenee) on cardamom

Abstract

The results on cardamom shoot and capsule borer indicated that the peak population was recorded in the month of second fortnight of May on both M-1 and M-2 varieties of cardamom (per cent shoot damage of 24.93 and 26.06, respectively). Whereas, the peak infestation on capsules was recorded in the month of November on both M-1 and M-2 varieties of cardamom (15.0 and 15.80, respectively). The correlation studies indicated that there was a significant positive correlation with relative humidity &rain fall with per cent shoot damage in M-1 and M-2 varieties of cardamom.
