A laboratory and field rearing technique for the predatory bug, Orius tantilus (Mots.), is presented. This was part of a three year project entitled "Development of a biological control - based IPM [integrated pest management] for the control of Asian corn borer, Ostrinia furnacalis (Guenee)", funded by the DA-BAR [Department of Agriculture-Bureau of Agricultural Research] from November 1990 to December 2002. The method was simple and used the following materials: petals of Vanda orchids for oviposition, 20% honey and plain water as moisture source; Suidasia pontifica Oudemann, eggs of Corcyra cephalonica Stn., Tetranychus truncatus Ehera and Dichromothrips corbetti (Priesner) as preys; flowers of Sesbania grandiflora L. as moisture source for developing nymphs, and zip-lock plastic bags as rearing units which can contain 100-200 predators per bag. In the field, 100 sq.m area planted with Amaranthus spinosus L. yielded 150-300 predators per plant three months after transplanting the weed
