Table 1 Alpha diversity metrics for all the treatments. Species richness was measured using Chao2 and observed species index. Species diversity was calculated using Phylogenetic diversity (PD) and the Shannon diversity index.

	Chao1	Observed species	PD	Shannon diversity index
PBS	486.78 ± 25.29^a	404.41 ± 26.82^a	25.87 ± 1.57^a	5.56 ± 0.46^a
PmSTAT dsRNA	491.64 ± 5.23^a	401.52 ± 16.15^a	24.94 ± 0.81^a	5.17 ± 0.26^a,b
PmSTAT dsRNA + WSSV	361.32 ± 13.74^b	268.41 ± 13.93^b	18.70 ± 0.75^b	3.46 ± 1.15^b,c
WSSV	382.73 ± 12.57^b	275.65 ± 11.42^b	20.52 ± 1.14^b	2.26 ± 0.39^c

Different superscript lowercase letters in the same column indicate significant differences among conditions (P < 0.01).
