Rhynchophorus ferruginenus Latin name is better known as the caterpillar is the larva of this sagu.Ulat red palm weevil. As a source of sago protein can be used as animal feed or substitute materials are also cholesterol-free nutritious side dish. These caterpillars live on sago stem rot. Usually it will appear on tree trunks that have completed the subscription sagunya. Rotting tree trunks arrival would provoke a herd beetles to lay their eggs there. Well, the caterpillars that come from eggs that hatched. Sago protein content of about 9.34%, while the main feed made from sago approximately 27.77%. In addition to a fairly high protein content, sago worm also contains several essential amino acids, such as aspartic acid (1.84%), glutamic acid (2.72%), tyrosine (1.87%), lysine (1.97%) , and methionin (1.07%). After cleaning sago fried so the outside crispy, but not until the break for the liquid inside is still intact. Kidu this fried then lightly cooked with spice turmeric, candle nuts, shallots, garlic. It feels? Hmm ... Crunchy exterior, the interior "broken" when bitten by it feels like smooth marrow. Perhaps because the caterpillars are fried, then I do not feel the sensation of raw milk. Part eyes caterpillar even a special sensation when eaten, crispy tenan. Then pour the tasty thick liquids and soft in the belly. Sago Worm History Sago is a clump of plants and reproduce by forming tillers. Sago trunk contains starch (carbohydrate), and is usually harvested after 8-10 years old. However, if properly cultivated plants, sago can be harvested at the age of 6-7 years. Waste from the sago tree yields vary and are generally not utilized. One of these wastes are sago stem shoots (1-2 m). This waste can be a place for red palm weevil (Rhynchophorus ferrugineus) to lay eggs. Red beetle larvae known as sago palm. Beetle is a pest of plants such as sago palm, palm oil, palm, and palm. Beetles are usually only interested to lay eggs on plants that have died, the palm trees that wound, and the remaining shoots Atang sago harvesting. Plants attacked coconut leaf beetle was marked with a limp because of the base of the leaves eaten by larvae. Larvae or usually known as sago is not exploited commercially. Though many people already know that prospective sago as a source of high protein. Sago can be obtained from nature, from the ripe tree felling crop waste, approximately 1-2 m at the top of the stem to tip. Harvest sago naturally done by looking for shoots or stems of sago waste that has been aged 30-40 days after the cut. To find the logs (sticks) there sago worm, carried out by listening. If there was no sound movable means in the log there are sago. Silkworm taken by splitting the stem and is usually found on the plot eating caterpillars. Number of sago sago logs generated each, both shoots and stems, varied. This variation is influenced by: 1) the length of time decay of the stem (spindle) sago for the development of larvae to be harvested, 2) the volume of the trunk or log that reflects the content of carbohydrates as a food source of larvae, and 3) other factors such as the number of female beetles lay eggs on spindle . As the process of trace formation in the trunk of sago larvae, then the writer doing research. Beetles usually fly during the day and happy perched on the stem of sago (also cane) that has been cut down and a little rotted. At the time, will lay eggs, female beetles bore holes with growled on the shaft of a wound or rot (wilt). 3 mm deep hole filled with 400-500 eggs. Egg-laying period lasts 1-3 months. Eggs will hatch in 2-3 days. Newly hatched larvae into the top of the stem and eat the soft tissue and remove the fibrous part out the hole, so that outside the hole will look the sap with dirt and used a strong-smelling foods. Larval period lasts about 2 months. The larvae can grow to a length of 5 cm and 2 cm wide at the middle. As will become pupae, larvae make a cocoon of cylindrical fibers. Pupal phase lasts 2-3 weeks. Coconut beetle life cycle of approximately 3.50 to 7 months. Sago harvest time is best at 39-45 days old instar larvae from logs found sago worms and larvae usually have a weight of 4.10 to 5 g respectively, and 5.10 to 6 g.
