Few studies have investigated the biological control potential for insect pests of grain storages in South East Asia, although several reports suggest that there is a large number of natural enemies in the region. Studies in rice storages in Thailand indicated that various natural enemies, including parasitoids, pathogens, predators and intruders such as ants [Formicidae], spiders [Araneae] and geckoes, play a key role in the suppression of pest populations. However, high infestation rates were also sometimes reported. Thus, more efficient control could be achieved by augmentative release of selected, mass-cultured natural enemies. Tables of biological control agents and their hosts in grain storages were prepared from the available literature to identify potential candidates for the region. The predacious bug, Joppeicus paradoxus, from Thailand is listed as a possible control agent. It is emphasized that extensive studies concerning the identification of species and their hosts, the selection o

f candidates, mass-production techniques, and timing and size of releases should be carried out prior to the implementation of a release programme.
