Water mites (Arrenurus spp.) parasitize adult dragonflies. We collected dragonflies weekly at 11 waterbodies in Greenville Co. and Pickens Co., SC, USA, to: (1) compare parasitism prevalence across species, sites, and sampling periods; (2) test the hypothesis that prevalence correlates with host abundance; (3) test the hypothesis that prevalence is inversely related to host diversity…
Brazil hosts a wide range of Odonata species, including many hitherto unde¬scribed ones, especially in remote and unexplored regions where logistics are difficult. The northwestern Brazilian Amazon is an example of this situation, and many locations still need to be sampled there and have their taxonomic inventories compiled.
Dragonflies and damselflies are hosts to a variety of parasites and pathogens. However, very few studies have investigated which viruses infect dragonflies and damselflies. Here, based on next generation RNA sequencing of RNA from Leucorrhinia dubia (Libellulidae, Anisoptera) and Coenagrion puella (Coenagrionidae, Zygoptera) larvae, data on putative viruses present in odonates are reported. In both…
