“…However, this relationship tends to be more specific within plant systems, as evidenced by Aphis craccivora , a vector of numerous plant viruses. It has also been discovered that most vectors of plant pathogens belong to the order Hemiptera [ 54 ]. Moreover, many studies reported the importance of pollinator species in plant development and reproduction [ 55 ].…”

This study reports the virome investigation of pollinator species and other floral visitors associated with plants from the south of Bahia: Aphis aurantii, Atrichopogon sp., Dasyhelea sp., Forcipomyia taiwana, and Trigona ventralis hoozana. Studying viruses in insects associated with economically important crops is vital to understand transmission dynamics and manage viral diseases that pose as threats for global food security. Using literature mining and public RNA next-generation sequencing data deposited in the NCBI SRA database, we identified potential vectors associated with Malvaceae plant species and characterized the microbial communities resident in these insects. Bacteria and Eukarya dominated the metagenomic analyses of all taxon groups. We also found sequences showing similarity to elements from several viral families, including Bunyavirales, Chuviridae, Iflaviridae, Narnaviridae, Orthomyxoviridae, Rhabdoviridae, Totiviridae, and Xinmoviridae. Phylogenetic analyses indicated the existence of at least 16 new viruses distributed among A. aurantii (3), Atrichopogon sp. (4), Dasyhelea sp. (3), and F. taiwana (6). No novel viruses were found for T. ventralis hoozana. For F. taiwana, the available libraries also allowed us to suggest possible vertical transmission, while for A. aurantii we followed the infection profile along the insect development. Our results highlight the importance of studying the virome of insect species associated with crop pollination, as they may play a crucial role in the transmission of viruses to economically important plants, such as those of the genus Theobroma, or they will reduce the pollination process. This information may be valuable in developing strategies to mitigate the spread of viruses and protect the global industry.

“…Molecular studies of fleas are increasing, but many taxa are described only morphologically and could be re-examined using new techniques in order to clarify their taxonomy. Better knowledge of fleas may help prevent diseases caused by some fleas as pests, parasites, or vectors of pathogens [27,52,83,103,[142][143][144][145][146].…”

This overview of extant Siphonaptera lists 19 families with major hosts and general distribution, estimated numbers of genera, species, and subspecies, with a brief taxonomic and phylogenetic review. With around 10 new species described annually, global flea fauna has an estimated extant 249 genera, 2215 species, and 714 subspecies, mostly mammal parasites but 5% of species are on birds. Host specificity varies from euryxenous (i.e. infesting two or more host orders)(e.g. cat fleas, Ctenocephalides felis felis) to monoxenous (e.g. rabbit fleas, Spilopsyllus cuniculi) . The largest family is the paraphyletic Hystrichopsyllidae, making up a third of all flea species. The largest monophyletic family, Ceratophyllidae (rodent and bird fleas), comprise another 20%, and has dispersed to every continent including Antarctica. Fleas descend from scorpionflies (Mecoptera), possibly snow scorpionflies (Boreidae) or Nannochoristidae, and even giant fossils found from the Mesozoic could be Siphonaptera. Flea diversification shows evidence of taxon cycles: "Relict" families such as helmet fleas (Stephanocircidae) have a disjunct distribution reflecting the breakup of Gondwanaland, 70 million years ago. "Niche specialists" include nest fleas (Anomiopsyllus), bat fleas (Ischnopsyllidae), and burrowing fleas, the chigoes (Tungidae). By contrast, Ceratophyllidae fleas could be considered "great speciators". Cat fleas and several other synanthropic flea species are invasive "supertramps". Although those species are intensively studied, many flea species and their hosts require urgent surveys and conservation.
