Abstract
Arthropods diversity in rice field with integrated crop management. Integrated crop management (ICM) has been introduced to improve rice intensification system in Indonesia. Organic matter has been recommended to be added into the rice fields to improve soil fertility. In order to minimize hazard of pesticide integrated pest management (IPM) is incorporated into ICM to control pest. The objectives of this research were to study arthropod diversity in rice field where organic matter was added and pesticide was used rationally. The research was conducted at experimental fields of Indonesian Center for Rice Research in Sukamandi, during the wet season of 2005/2006. Diversity of arthropod was observed in ICM, organically-farm field, and farmer technique paddy fields. Arthropod was sampled using a FARMCOP suction apparatus. Results of this study indicated that in ICM paddy fields were harbored by more insect, predators and parasitoids especially during early growing stage of rice plants. Thus adding organic matter and rationaly use of insecticide could increase the natural enemies for insect pests in the field.
