UJI PREFERENSI HAMA PASCA PANEN (Sitophilus oryzae) PADA BEBERAPA JENIS BERAS (MERAH, HITAM, COKLAT, PUTIH) DI LABORATORIUM

Rice is a staple food that plays an important role as the main source of calories in Asia, including Indonesia. Rice contains relatively complete nutrients, including carbohydrates, protein, fat, crude fiber, and various vitamins. In Indonesia, rice consumption is very high, reaching around 139.15 kg per person per year and continues to increase by 95% each year. Therefore, increasing rice production must be accompanied by optimal post-harvest management to reduce damage and loss of yield. Sitophilus oryzae, known as the rice beetle, is the main pest that attacks and breeds in stored rice. S. oryzae causes significant damage and contamination to grain. This study aims to study the preferences of S. oryzaes for white rice, red rice, brown rice, and black rice. The results of the study showed that the highest population of live imago was in black rice was 83.28, the highest weight loss in white rice compared to other types of rice was 47.84 ± 1.03 and the average percentage of perforated and damaged rice was the highest 5.83 ± 1.94, making it the type of rice most preferred by S. oryzae.
