Economic impact of sugarcane moth borers in Indonesia* [Full subscriber]

Abstract Field experiments were conducted over two years in Indonesia (East Java) to investigate damage levels, yield decline and economic impact of three major sugarcane moth borers Chilo sacchariphagus and C. auricilius (referred to as stem borers) and Scirpophaga excerptalis (referred to as top borer). Different levels of borer damage were created to allow comparison between plots treated, i.e. biocontrol and insecticide applications and untreated plots that were naturally infested. In the plant cane experiment, damage levels in untreated plots were the highest, with an average of 14.5% internodes bored by Chilo spp. and 15.8% stalks damaged by S. excerptalis.…
