Résumé : THE INDONESIAN SUGARCANE industry in Java is affected by a number of moth borers that very substantially reduce the productivity of commercial crops and sugarcane streak mosaic virus has recently been identified in the Indonesian sugarcane industry. The Australian sugarcane industry is currently free of major moth borer species, though on a world stage moth borers are extremely destructive and difficult to control. During the last four years, BSES scientists have been collaborating with Indonesian experts to research Integrated Pest Management (IPM) strategies to provide more effective moth borer control. The research has principally focussed on specific parasitoids (mainly Trichogramma species) and mass-release strategies for control of species of Scirpophaga and Chilo. Recent work has enabled more effective treatments to be identified. Other research has investigated sugarcane streak mosaic and canegrub management. A vector for sugarcane streak mosaic virus (brown aphid) has been identified and other forms of transmission investigated. The paper outlines a broad range of activities encompassed in this work and complements a paper focusing on extension outcomes in the Indonesian industry.
