Microorganisms are integral to ecosystem functioning and host adaptation, yet the understanding of microbiomes in diverse beetle taxa remains limited. We conducted a comprehensive study investigate microbial composition two red flat bark species, Cucujus haematodes C. cinnaberinus, assessed influence taxonomic relatedness tree species on their microbiomes. sampled 67 larvae taken from 11 species. 16S rRNA V4 fragment sequencing revealed distinct communities associated with each significantly influencing microbiome composition. Alpha beta diversity metrics indicated significant differences between both Principal component analysis clustering based but not for This overlap could be attributed similar ecology The detection various bacteria, among which some have already been reported saproxylophagous beetles, suggests that beetles ingest bacteria via foraging other wood-dwelling invertebrates. Our findings show complex interplay taxonomy, microhabitat Cucujus, providing insights into ecological roles conservation implications. research helps fill gap dynamics saproxylic sheds light factors shaping highlights importance considering environmental conditions when studying insect-microbe interactions forest ecosystems.

Field surveys conducted during 2021 and 2022 in Western Sicily, Italy, revealed the presence of common fig trees severely affected by trunk crown root canker bark cracking. Moreover, conjunction with symptomatic tissues, same surveyed plants showed beetle holes internal wood galleries. The predominant Criphalus dilutus was previously reported attacking figs Sicily. Phylogenetic analyses based on multilocus DNA data different fungal taxa associated disease symptoms, including Botryosphaeria dothidea, Ceratocystis ficicola, Diaporthe foeniculina, Neocosmospora bostrycoides, N. perseae, Neofusicoccum luteum. Pathogenicity tests potted that all species were pathogenic to fig, C. ficicola spp. as most aggressive species. isolations from bodies emerging adult insects recovered samples confirmed spp., suggesting potential involvement their dissemination.
