Corn in South SulawesiThe study aimed to investigate the role of predators in preying\udthe larvae and pupae of corn stem borer, Ostrinia furnacalis Guenee\ud(Lepidoptera: Pyralidae) was conducted in the farmer corn field during\ud2011. Two plant hills each of which 6 meter away were prepared one of\udwhich unglued and the other one glued for ground and canopy predators.\udOn each plant, 5 larvae instar-2 and or -3 were made available (2 larvae at\udinternode near the ground surface, 1 near the corn ear, at internode between\udear and tassel and at the upper top internode respectively). The experiment\udwas carried out with 10 replications so there were 20 plant hills prepared.\udThe experiment was also carried out with the same procedures for pupae.\udThe predators, visit frequency and the number of preys consumed by\udpredators were recorded. The results indicated that there were 5 groups of\udpredators i.e., ants, spiders, cricket, Coccinella sp., Chrysopa sp. and\udPaederus sp. were found to visit larvae and pupae on plant corn. The ant\udpredator visit more frequently the prey larvae and pupae on both unglued\udand glued plants and only this predator recorded to prey larvae with the\udmean of 2.5 (50%) and 1.9 (38%) and pupae with the mean of 3.2 (64%)\udand 3.0 (60%) in 14 h period on glued and un-glued plants respectively.\udThe ant, Solenopsis sp. found in this study can really be promoted as biological\udcontrol for Asian corn borer
