Abstract
The experiment was carried out to study the population dynamics of cardamom shoot and capsule borer, Conogethes punctiferalis(Guen.) at the Zonal Agricultural and Horticultural Research Station (ZAHRS), Mudigere during 2022-23. Infestation of borer was present throughout the year, but peak infestation on shoot was recorded in the month of December (56.67%). Whereas, infestation on capsules peaked during first fortnight of December (33.65%). The correlation studies revealed that there was a significant positive correlation with maximum temperature and sunshine hours for shoot infestation. While, morning relative humidity had significantly positive correlation with capsule infestation. However, rainfall had significant negative correlation for both shoot and capsule infestation.
