Abstract
Leucopholis irrorata Chevrolat is a perennial white grub pest of the dryland rice-maize cropping pattern in localized fields of Batangas, Philippines. Adults emerge from underground pupal cells and fly to nearby host trees before oviposition in response to the onset of monsoonal rains after a 3-month dry season coterminous with establishment of the rice crop. Damage via loss of stand occurs on the following young maize crop when the white grub population is composed of 3rd-instar larvae. Maize fields with perennial damage are located near adult flight trees in areas where sugarcane is the predominant crop. Furrow-applied lindane granules at 0.25 kg of AI/ha during sowing of rice provide year-long control of this univoltine species at a cost small-scale farmers can afford.This publication has 0 references indexed in Scilit:
