A trial was conducted from July 2015 to November 2015 to see the effect of nutrition on Lac cell production and transmission losses. The mean fresh weight of 100 mature healthy lac cells obtained from the sticklac at harvest varied from 6.36g (T8-Control) to 11.14g (T7). There was a significantly difference in the mean weight of 100 fresh cell weight in T7, T2 and T3 over the control, however T7 and T2 were at par with each other. The mean dry weight of 100 healthy cells of lac insect was obtained seven days after shady drying varied from 4.95 g (T8 – control) to 8.21g (T7 – Humic acid + Auskelp). There was a significant difference in the mean dry weight in 100 lac cell of T7, T2 and T3 over the Control (T8), however but the former two were at par. The dry cell weight contributed significantly in the lac yield. The mean dry weight (g) of 100 cell of lac insect differed significantly among the different treatments.
