The total number of white grubs present in the root zone of a palm can be estimated by the regression equation Y = 3.78 + 1.7938 x, where Y is the total population of white grubs found around a palm and x is the number of insect stages found upto a depth of 40 cm at a distance of 50 to 100 cm away from the trunk of the palm.enArticle
