Effect of Different Organic Wastes on the Growth of Black Soldier Fly (Hermetia illucens) Larvae

摘要

Black soldier fly (BSF) is one of the most promising bioconversion agents for organic wastes and potential nutrient-rich food source for the poultry and aquaculture industries. For these purposes, it is essential to produce edible quality larvae of BSF. This study tested the effect of the oil palm dregs (oil palm shreds after the oil is squeezed out), soybean curd residue, and restaurant waste as food on the survival and growth of BSF larvae. About 25 BSF larvae age of six to seven-days-old were placed on each treatment substrates (oil palm dregs, soybean curd residue, and restaurant waste). At 5, 12, and 19 days after treatments were started, all larvae on each treatment were collected for measurements. Results after 19 days showed that the restaurant waste, a mixture of food from West Sumatran food restaurants (RM Padang) and Javanese food restaurants (RM Tegal), produced significantly (P<0.05) longer body length and width, along with heavier body weight compared to the larvae fed with the other two treatments.
