This study aims to determine the efficiency of M. oleifera and C. longa mixed with egg custard as a booster for M. rosenbergii larvae. A total of 8 experimental diets; T1 (Egg custard + 1% turmeric), T3 (Egg custard + 3% turmeric), T5 (Egg custard + 5% turmeric), M1 (Egg custard + 1% moringa), M3 (Egg custard + 3% moringa), M5 (Egg custard + 5% moringa), TM1 (Egg custard + 1% moringa and 1% turmeric) were tested on day 10 of M. rosenbergii larvae. Egg custard was used as control diet and larvae in all treatments were fed with Artemia sp. during night time. Proximate analysis was done to determine crude protein, metabolize energy, lipid, ash, moisture content and crude fibre in each egg custard formulations. Feeding trial was carried out for 30 days. Stocking density was set at 30 larvae/L for each treatment. Larvae stage index (LSI), survivability, first day post larvae (PL) appear, weight and length were measured. It is expected that M5 diet contain more crude protein than other diet formulations. Present study showed that there were significant findings (P ≤ 0.05) in all parameters except for LSI. M5 diet showed significant survivability rate (12.13±1.12%), weight (15.86±0.012mg) and length (1.06±0.081cm). However, among all treatments, the earliest day larvae turned into PL was recorded in TM1 diet. In conclusion, M. oleifera could potentially enhance survivability and growth of M. rosenbergii larvae.
