Abstract

Planthoppers and bugs were pest especially to rice plant in the fresh swamp and the tidal land of South Sumatera. Sintetic insecticide used to control on planthoppers and bugs by farmers. B. bassiana was entomopathogenic that could used as micoinsectiside to control on the pest and safe to environment. The purpose of this research was to determine the effects of application solid and liquid mikoinsecticide to the population and attacking of planthoppers and bugs and also abundance of spiders inhabiting fields applied by micoinsecticide and applied by sintetic insectiside. The method of this research was experiment on the ricefield and purposive sampling to the sample plant. Planthoppers, bugs and spiders were sampled using web and pitfall traps. The population and attacking of wereng was higher in vegetative phase than generative phase in the fresh swamp and the tidal land of South Sumatera. The population and attacking of planthoppers and bugs was higher in field without micoinsecticide application than field micoinsecticide. The population of planthoppers as highest in the fresh swamp to field applied by micoinsectiside 19 tail per 80 clump and in the tidal land 47 tail per 80 clump. The population of bugs was highest in the fresh swamp 19 tail per 80 clump and in the tidal land 53 tail per 80 clump. The attacking of planthoppers was highest in the fresh swamp 2.24% and in the tidal land 4.17%. The attacking of bugs was highest in the fresh swamp 2.47% and in the tidal land 2.24%. Abundance of spiders on the leaf was highest in the fresh swamp was Tetragnathidae 59.1% and in the tidal land 46.1%. Abundance of spiders on the top soil was highest in the fresh swamp an in the tidal land was Lycosidae 100%. Diversity of spiders on the leaf was highest in the fresh swamp 2.17 and in the tidal land 2.25. Diversity of spiders on the top soil was highest in the fresh swamp 1.52 and in the tidal land 1.43.
