The Incidence of grubs and adults of hadda beetle, H. vigintioctopunctata started in the last week of December and reached peak in third week of March to first week of April, then declined gradually thereafter. A significant positive correlation (r = 0.506 & r = 0.594) was found between populations of grub and adults of hadda beetle with maximum and minimum temperature; while significant negative correlation (r = -0.538 & r = -0.535) was found between population of adults and maximum and minimum relative humidity while non-significant positive correlation was found between population of grub and adult with rainfall.
