Effect of Effective Concentration of Azolla Supplementation at Different Frequency of Feeding to Fifth Instar Silkworm

An experiment conducted to know the effect of effective concentration of azolla i.e. 50 per cent was supplemented to fifth instar silkworms once in a day, twice in a day and thrice in a day. The silkworm hybrids reared on mulberry leaves supplemented with 50% azolla concentration feeding once in a day during fifth instar showed superiority in all quantitative parameters of silkworm followed by fourth instar. However, feeding twice a day with 50% azolla concentration supplemented leaves was next best supplement. Hence, azolla as a feed supplement at 50% concentration can be conveniently utilized to enhance the silk production.
