Obligate symbionts in sap-sucking hemipterans are harbored in either the same or different organs, which provide a unique perspective for uncovering complicated insect-microbe symbiosis. Here, we investigated the distribution of symbionts in adults of 10 -free cicada species of 2 tribes (Sonatini and Polyneurini) and the co-phylogeny between 65 cicada species and related symbionts ( and YLSs). We revealed that YLSs commonly colonize the bacteriome sheath besides the fat bodies in these two tribes, which is different with that in most other -free cicadas. Co-phylogeny analyses between cicadas and symbionts suggest that genetic variation of occurred in Sonatini and some other cicada lineages and more independent replacement events in the loss of /acquisition of YLS in Cicadidae. Our results provide new information on the complex relationships between auchenorrhynchans and related symbionts.

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is a major pest of global citriculture. In the Americas and in Asia, D. citri vectors the phloem-limited bacterium, Candidatus Liberibacter asiaticus (CLas), which causes the fatal citrus disease huanglongbing, or citrus greening.

The gut microbiome plays an important role in insect evolution and ecology. Bacteria support the host's nutrition and defense and therefore play an important role in the fitness of the host. Halyomorpha halys is one of the most important invasive pest species in the world.

Wheat is the third most widely consumed cereal in the world, after maize and rice. However, it is regularly attacked by the wheat aphid (), causing considerable damage to wheat crops. The acetylcholinesterase enzyme, which plays a key role in the transmission of the synaptic cholinergic signal, has emerged as a promising target for the development of pest control strategies.

The Nearctic leafhopper (Hemiptera: Cicadellidae) is the primary vector of ' Phytoplasma vitis', the causative agent of Flavescence doreé in Europe. Although microorganisms play an important role in the ecology and behavior of insects, knowledge about the interaction between and microbes is limited. In this study, we employed an amplicon metabarcoding approach for profiling the V4 region of the 16S rRNA gene to characterize the bacterial communities of across several populations from four European localities.
