The parasitic species encountered were the braconid, Scymnus (subgenus sp., and the eumenid, (Suss.). Agathis Microdus) Odynerus fervidus Natural enemies were found mainly between the reproductive and ripening phases of the crop. Predators such as and sp. were observed mainly on rice plants infested with Cheilomenes sulphurea Cheilomenes the rusty plum aphid, (Th.), while spiders were observed feeding on small Hysteroneura setariae dipterous insects and cicadellid bugs such as (Mel.). In general, the overall Nephottetix modulatus population of natural enemies was higher on the late season crop. The tettigoniid, and C. conocephalus the reduviid. spp., were the most abundant during both seasons. Rhinocoris In conclusion, we believe that the high population of grain feeders (D.
