| Abstract | ||
| The seasonal incidence of P. blanchardii on datepalm was mild during May and June and then on the onset of monsoon its population increased and reached to maximum during December and January months. The highest population of this pest was recorded during the month of January while, minimum in the month of June. The scale population showed a significant negative correlation with maximum and minimum temperatures. While non-significant negative correlation with maximum relative humidity and rainfall. However, minimum relative humidity had a significant negative correlation. | ||
