Three new species of the genus Alluaudomyia Kieffer, 1913 (Diptera, Ceratopogonidae) from the National Park of Hainan Tropical Rainforest, China.

ABSTRACT: Three new species of the predaceous midges of genus Alluaudomyia Kieffer, 1913: A.flavinotum Wu & Li, sp. nov. of the maculipennis group, and A.reflexuralis Wu & Li, sp. nov. and A.limu Wu & Li, sp. nov. of the parva group, are described from the National Park of Hainan Tropical Rainforest, Hainan Island, China. Illustrations and COI barcodes (a fragment of the mitochondrial cytochrome c oxidase subunit 1) of the three new species are also provided. Associations of male and female specimens of two species (A.reflexuralis Wu & Li, sp. nov. and A.limu Wu & Li, sp. nov.) are supported by DNA barcodes. The parva group is reported from China for the first time.

Project description:BackgroundCulicoides imicola Kieffer and Culicoides bolitinos Meiswinkel (Diptera: Ceratopogonidae) are both of veterinary importance, being vectors of Schmallenberg, bluetongue and African horse sickness (AHS) viruses. Within South Africa, these Culicoides species show a marked difference in their abundances according to altitude, with C. imicola highly abundant in lower altitudes, but being replaced as the dominant species by C. bolitinos in cooler, high-altitude regions.MethodsThe thermal physiology of field collected adults of each species was determined to evaluate whether it could account for differences in their distribution and abundance. Critical thermal maxima (CTmax) and minima (CTmin), as well as upper and lower lethal temperatures (ULT and LLT) were assessed after acclimation temperatures of 19'C, 24'C and 29'C. Critical thermal limits were determined using an ecologically relevant rate of temperature change of 0.06'C x min(-1).ResultsSignificant differences in CTmin and CTmax were found between acclimation temperatures for C. imicola and C. bolitinos. In C. bolitinos, the LLT of individuals acclimated at 24'C was significantly improved (LLT50 = -6.01'C) compared with those acclimated at the other temperatures (LLT50 = -4'C). Acclimation had a weak (difference in LLT50 of only 1'C) but significant effect on the LLT of C. imicola. When CTmin, CTmax, LLT and ULT were superimposed on daily maximum and minimum temperature records from locations where each tested Culicoides species is dominant, it was found that temperatures frequently declined below the CTmin and LLT of C. imicola at the location where C. bolitinos was dominant.ConclusionsThe distribution and abundance of C. imicola is likely directly constrained by their relatively poor tolerance of lower temperatures. Results for C. bolitinos suggest that the adult phase is hardy, and it is hypothesised that the thermal biology of other life stages could determine their range.

Project description:Culicoides spp., a common biting midge genus, are haematophagous insects that can transmit pathogens to humans and other animals. Some species transmit arboviruses, including bluetongue virus, epizootic haemorrhagic disease virus, African horse sickness virus and Schmallenberg virus to vertebrates, which can be detrimental to livestock and wild animals. Culicoides spp. can also have a diversity of insect-specific viruses (ISVs) that can only be transmitted between insects and others related to known arboviruses. For Culicoides brevitarsis and other Culicoides spp. in Australia, the virome is largely unexplored. We used high-throughput sequencing to characterise the virome of C. brevitarsis collected from Casino, New South Wales, Australia. For virus detection, the total RNA was extracted from pools of C. brevitarsis followed by rRNA depletion and Illumina short-read-based RNA sequencing. The reads were quality-checked, filtered and assembled into contigs, compared with the non-redundant protein and conserved domain databases for viral detection and genome organisation, respectively. The phylogenetic analysis was used to further characterise the viruses. We detected new virus diversity including ten viruses belonging to eight different families with complete or near-complete coding regions. Seven of these were novel virus species belonging to the families: Chuviridae, Orthomyxoviridae, Peribunyaviridae, Qinviridae, Rhabdoviridae and Solemoviridae. In addition, the novel Peribunyaviridae virus should also be considered part of a new genus. Whilst most of the detected viruses grouped into families with viruses that can infect insects, animals or both, the novel species of Solemoviridae was closely related to an economically important plant pathogen, the sugarcane yellow leaf virus. Our quantitative PCR-based screening confirmed the absence of any Wolbachia endosymbiont within the collected samples. Furthermore, we detected fragments of three more virus families known to infect fungi and plants. The detection of potential arboviruses and ISVs in Culicoides spp. is important in understanding virus epidemiology.
