摘要

Investigation was carried out to evaluate and improve semi-synthetic diet for mass rearing of Brinjal shoot and fruit borer, Leucinodes orbonalis Guenee. Three published semi-synthetic diets (diet A, B and C) were evaluated for two successive generations and compered with the natural host potato. Among the semi-synthetic diets, diet A recorded significantly highest pupal recovery of 38.35% and fertility of 75.75% but not as comparable as natural host potato, which recorded 65.33% pupal recovery and 78.37% fertility. Diet A was further improved by adding potential substituents like linoleic acid, α-tocopherol and host plant-based components among those, brinjal fruit powder-based diet performed better with 57.83% pupal recovery and 79.53% fertility. Significant increase in developmental durations were recorded in all the semisynthetic diet in comparison with the natural host, but there was a slight improvement in all the biological parameters recorded because of successive rearing.
