Exploration of Symbiotic Bacteria of Oryctes rhinoceros (Coleoptera: Scarabaeidae) Larvae from Oil Palm Empty Fruit Bunches

Oil palm empty fruit bunches (OPEFB) were utilized as the source of organic fertilizer, but become a medium Oryctes rhinoceros proliferation in oil plantations. O. uses cellulose, hemicellulose and lignin OPEFB energy sources for larvae growth development. In process breaking combining complex compounds into simple molecules, they are establishing symbiotic relationship with bacteria residing digestive tract larvae. Isolation was carried out aim identifying third instar found OPEFB. This research done by using descriptive method. Exploration conducted through two stages. The first step attained isolating, growing multiplying conducting biochemical testing. second phase accomplished molecular testing bacterial identification. results showed that isolates after molecularly sequenced based on 6S rDNA, species identified Bacillus stratosphericus, B. siamensis, cereus, Haemophilus parainfluenzae, Achromobacter xylosoxidans, Alcaligenes faecalis. also several originating from hindgut rhinoceros.
