Abstract
The present study was conducted to compare the influence of two primary host plants, Som (Machilus bombycina King) and Soalu (Litsea polyantha Juss) on the haemogram of Antheraea assama Westwood. The Total Haemocytes Count (THC), Differential Haemocytes Count (DHC) and Blood volume (BV) of different developmental stages (larval instars and pupae) of A. assama reared on the two selected host plants, Som and Soalu was studied in the laboratory.Quantitative analysis of haemocytes in both the groups reared on different host plants have shown that the THCs increased continuously from 1st to 5th instar larvae and recorded a steep decline in the pupa of both the groups. Though THC was not significantly different between the early instars (i.e, 1st, 2nd and 3rd instar larvae) reared on the two host plants, there was a significant difference in total count in the matured instars and pupae suggesting the impact of host plant. Comparison of the different haemocyte types (PR, PL, GR, SP and OE) between the som and soalu reared groups of A. assama did not show any significant variation between them. However, a slight difference was recorded in PR at the 2nd and 3rd instars along with pupa, being significantly higher in M. bombycina reared insects. Studies showed that the pattern of changes in blood volume in som and soalu reared groups were similar to that of THC. Significant difference in blood volume between the two groups was recorded only in the 5th instar larva of A. assama, BV recording higher in those reared on L. polyantha.

Key words: Antheraea assama, som, soalu, haemogram, haemocytes
