The rice black bug (RBB), Scotinophara spp. (Hemiptera: Pentatomidae) is an emerging pest problem in the Philippines. Both adults and nymphs are cryptic sap-feeders. Intensive feeding may result in 'bugburn' and total crop loss. Irrigated areas adjacent to marshy habitats are prone to RBB infestation. RBB outbreak was first recorded in Palawan Island in 1982 and had spread to Mindanao between 1992 and 1997 and to the Visayas in 1998-1999. By 2005, RBB was already threatening the Bicol Region based on light trap catches in the municipalities of Bulan and Gubat in Sorsogon Province. Updates on the RBB species diversity, population dynamics, distribution pattern, host plant range, natural enemies, and management options to reduce populations to non-damaging levels are presented.
