Abstract:
The population density of Lac insect was recorded by counting insects (later lac cells) per 2.5 sq cm on three branches per tree and at three fixed points per branches at 50, 62, 76 and 94 days after BLI. At 50 days after BLI, the mean population density of K laccaper varied from 44.95 to 50.28 in different treatments. There was significant difference in the mean population density of Lac insect in T3, T5 and T8 over T6. The former three were at par with each other. It was highest (50.28) in T3 Multiplex and lowest (44.95) in T6 Humic acid + Bolt acid + Bolt. At 62 days after BLI, the mean population density of Lac insect varied from 37.05 to 39.34 in different treatments but was at par among the treatments. It was highest (39.34) in T3 -Multiplex and lowest (37.05) in T2-Auskelp super. The mean population density of lac insects reduced at 76 days after BLI and it varied from 28.37 to 33.46. At 94 days after the BLI, the mean population density of lac also reduced in comparison to that on 50th day after BLI. It varied from 20.86 to 26.05 per 2.5 sq. cm. The mean population density of lac insect differed significantly in case of T3 – Multiplex over the Control (T8). It was highest (26.05) in case of T3, lowest (20.86) in T8.
