Functional analysis of Dicer, Argonaute, and sil genes in Tribolium. Larvae and pupae that were injected with dsRNA for (a-c) Dicer, (d-g) Argonaute, or (h-k) sil genes prior to EGFP RNAi. RNAi for Dcr-2, Ago-2a, or Ago-2b reduces the efficiency of EGFP RNAi (b, c, e-g). In contrast, RNAi for Dcr-1, Ago-1, or sil genes does not affect EGFP RNAi (a, d, h-k).
