Few pest problems have had more impact on the development of biological control than the resurgence of brown planthopper on rice. The key role of natural enemies in keeping this pest in check and the disruptive effect of insecticides on this balance have stimulated research on integrated pest management (IPM) throughout Asia and have led to unique and successful experiments in training and research into rice-pest management at the farmer level. An understanding of the identity and role of natural enemies in rice systems must be a crucial research component of any future rice program. Quantitative methods have been developed and key questions for further work include: Are the key natural enemies the same in different ecological and geographical zones? and What processes govern the recovery of natural enemy populations after disruption? There are other effects of intervention on biological control in rice. Future research on pesticides must take these interventions into account. Research on plant resistance, where the fundamental, population dynamics link between plant resistance, pest growth and survival, and natural enemy impact, must also be directed towards strategies for IPM. Research on the impact of natural enemies on populations of rice pests, may lead to the search for effective natural enemies of erotic pests that have recently invaded ricefields in the tropics. Attempts to research the role of microbial agents as interim measures to control occasional outbreaks of key pests should be preceded by studies to evaluate the ability of these agents to keep pest populations in check under existing field conditions.
