Light Trap Catches of White Grub and its Relation with Climatic Factors

Attempt was made to correlate white grub beetle emergence with the climatic factors viz., maximum, minimum temperatures, R.H. and rainfall. The study revealed that maximum and minimum temperatures, R.H. and rainfall during peak month (July) harboured maximum light trap catches. Higher temperature during May-June, low temperature during December, January and February, higher low temperature, R.H. and rainfall of preceding 11 and 12 months favoured beetle emergence, while, rains during April, October and November disfavoured beetle emergence.
