PENGARUH CAMPURAN DAUN JERUK PURUT (Cytrus Hystrix) PADA SIMPANAN BERAS TERHADAP PERKEMBANGAN POPULASI Sitophillus oryzae

Nabati insecticide was used for chemical control have been developed from Integrated Pest Management. Citrus leaf can be used to control because citrus leaf can repellents Sitophilus Oryzae pest, so that rice can avoid of pest attact for along time. The research used Complete Randomized Block Design consist of four treatment and six replication. The treatment consist of rice with purut citrus leaf without drying (BO), rice with purut citrus leaf drying 5 hour (B I), rice with citrus leaf drying 10 hour (B2), and rice with citrus leaf drying 15 hour (B3). The result of the research was period drying of purut citrus leaf could effect the population of S. oryzae. The longer period of purut citrus leaf indicated the increased population of S. oryzae. The lowest population of S. oryzae was in purut citrus leaf without drying, and the highest population in citrus leaf dlying for 15 hour
