A total of 97 microRNAs (miRNAs) were identified in worker-caste termites, while 101 were identified in nymph-caste termites, of which 65 were shared between these castes. While miRNA expression levels in worker-and nymph-caste termites had a strong positive correlation, considerable differences in such expression between worker-and nymph-caste termites were also observed. Among the miRNAs upregulated in workers, miR-278-3p showed the greatest difference of 3.84-fold, while among the miRNAs
