Abstract
Since many years, presence and activities of herbivorous insect very crucial in the agricultural ecosystem. Purpose of the research is to study biodiversity herbivores insect in rice organic and inorganic. The places used in the research divided into organic and inorganic rice field with measurement 25 m x 25 m, respectively. The insect samples collected used ubinan system methods with diagonal intersection applied for sweep net, pitfall trap and yellow trap. The samples from organic and inorganic rice analyzed Shannon-Wiener Index. The result of Shannon-Wiener Index was showed the higher number of herbivore insects in the inorganic rice field (H^ = 1.71) with population of herbivores about 391 individual (51%). In contrast, result of organic rice field (H^ = 1.68) lower than inorganic. Also, population of herbivores insect 372 individual (49%). The rice harvest was higher in the organic rice field (297 kg) than in the inorganic (279,2 kg).
