Rice black bug infestation in the island of Leyte was noticed in late 2001 in Libagon, Southern Leyte. Spread of infestation continued irregularly in many municipalities of Leyte in a year. Light trapping, delayed and synchronous rice planting, duck herding, handpicking of rice blag bug, fallowing, weeding and application of Metarhizium anisopliae were some of the control strategies done by farmers in reducing rice black bug population. Natural enemies that were observed to be present in the field were Solenopsis sp. (red ant), Micraspis crocet Mulsant (coccinellid beetle), Ophionia nigrofasciata (Schmidt-Goebel) [ground beeetle], Metioche vittaticollis (cricket), salticid (jumping spider), Tetragnatha sp. (four-jawed spider), Lycosa sp. (ground spider), and Oxyopes sp. (lynx spider), Telenomus sp. (Order Hymenoptera, wasp) and M. anisopliae (green muscardine fungus)
