Assessment of Insect from the forest area to the disturb area has been used to determine the variety and distribution of Insect along the change in the Eastern slope of Sewu Mountain, Wonogiri Regency, Central java Province of Indonesia. Using analysis of variance on several trapping method on the ground and canopy difference by the night and day period during rainy season and dry season on 2008 resulted the significant difference on each landscape's biodiversity. Lepidophtera, Hemiphtera and another foraging family increase from the forest to ricefield landscape while Diphtera and Coleoptera dicrease respectively. Using four insect families (Lepidophtera, Hemiphtera, Diphtera and Coleoptera) as the indicators showed there are no significant difference between protected forest, plantation forest and agroforest, while in the monoculture rice was dominated with Lepidophtera and Hemiphtera. Agroforestry environment has high potencial to develop for maintaining biodiversity even in the disturb environment
