The brown planthopper (Nilaparvata lugens) is a small planthopper that feeds on rice plants. There were numerous brown planthopper outbreaks in Southeast Asia in the 1980s and new ones are expected[1]. It is believed that excessive use of urea as nitrogenous fertilizer and insecticides can lead to outbreaks by increasing the fecundity of the brown planthopper, and reducing populations of natural enemies. Predators of this insect include the spiders Pardosa pseudoannulata and Araneus inustus.
