A Review on Brown Planthopper (Nilaparvata lugens Stål), a Major Pest of Rice in Asia and Pacific
Abstract: Rice (Oryza sativa L.) is the most important staple food in the world including Asia and Pacific. Millions of people around the world depend on rice due to the high calories and economic returns it provides. More than 100 species of insects including 20 economic pests are capable of causing notable damage to rice plants. Insect pests continue to pose threat to rice farming since rice plants serve as their host plants. Pests are major constraints to rice production and coexist with rice growth. Information on pest economic importance, description, biology, distribution, economic threshold level, population dynamics, monitoring and forecasting is a prerequisite. This review is focused on brown planthopper (Nilaparvata lugens Stål) which is an important economic rice pest that are prevalent in tropical rice growing regions. Brown planthopper (BPH) is a serious pest of rice and has tremendous impact especially in Asia-Pacific region. Understanding the biology and ecology of this pest will enhance the designing, formulation and utilization of effective control measures. The control strategies as stipulated by integrated pest management (IPM) should be eco-friendly with minimum use of synthetic pesticides while boosting the activities of natural enemies and other biological control agents. The control measures discussed in this paper are oriented towards the cultural and biological aspects of managing the pest.
