Soil arthropods and earth worms were exposed to the different insecticides under field conditions for about 105 days. The observed taxa of soil arthropods consists mites, collembola symphylla, millipede, centipede, pseudoscorpion, diplura and ants in areca garden ecosystem. The aim of the study was on effects of insecticides on selected beneficial non targeted soil arthropods and earthworms. The results revealed that Chlorpyriphos 20 EC 10 l/ha were found to have negative effect on soil arthropods. Whereas, Phorate 10G 25Kg/ha and fipronil 5 SC 2.5 l/ha were cause toxic effect on earth worms. By using various chemical for controlling of areca nut root grub will cause toxic effect on the soil arthropods and earth worms in both the location Harakere and Gulukoppa. Although the application of Chlorpyriphos and Fipronil was efficient in controlling populations of areca nut white grub (Leucopholis lepidophora Bl.), as we expected, they negatively affected non-target arthropods and earth worms in the soil surface. Hence, areca growers go for integrated pest management practices.
