SUMMARYBiting midges of the genus Culicoides (Diptera: Ceratopogonidae) are vectors of a number of viral diseases worldwide. Following the unforeseen outbreak of bluetongue in northern Europe (2006–2009) there was a need to clarify on-farm breeding substrates utilized by temperate Culicoides spp. Six substrates (cow dung, cow slurry, horse dung, sheep dung, maize silage and soil) were investigated for Culicoides spp. emergence over a 31-week period. Overall, most Obsoletus group Culicoides emerged from the cow dung and the most Pulicaris group Culicoides emerged from the sheep dung. Furthermore, Culicoides of the Obsoletus group were found to be abundant in cow slurry and sheep dung. Temperature played a significant role in the emergence times of adult Culicoides. The Obsoletus group appear to have undergone 3 generations during the experimental period. The sex ratio of emergent Obsoletus group Culicoides was affected by substrate type, with a greater proportion of males emerging from cow dung and slurry compared with the other substrates.

Culicoides Biting Midges

Culicoides biting midges (Diptera: Ceratopogonidae) are responsible for the transmission of a large number of pathogens to livestock and wild animals. In this study the presence of the genus, using light traps based at four different sites within the National Zoological Gardens of South Africa, was investigated during 2002-2004. In total, 37 species were recorded, including large numbers of Culicoides imicola Kieffer, 1913, which is responsible for the transmission of economically important arboviruses in South Africa, Europe, Middle and Far East. These results are discussed with reference to the wider Culicoides fauna in the Onderstepoort area of South Africa, their vector competence as well as biosecurity at the National Zoological Gardens.

Additional records of Elasmopus vachoni Mateus and Mateus, 1966 together with description of its its poorly-known mouthparts is provided, based on material from Tarifa Island (southern Spain). The known geographical distribution of this species extends from the Gulf of Guinea to the northern part of the Iberian Peninsula, all along its Atlantic and Mediterranean coast, also extending to Canary and Azores Archipelagos. Additionally, an identification key of Elasmopus species mentioned in European waters (ERMS area) is also given.

Three developmental abnormalities were found out of a total sample of eight hundred and twenty two within the genus Culicoides. These are two rare cases of double abdomen in females of the Schultzei and Imicola groups and a polar gynandromorphism, all in the genus Culicoides (biting midges) from Makurdi, Benue State, Nigeria. These females show double symmetrical abdomens equally attached to the meta-thorax and are related both on dorsal and ventral relative positions as well as larger and smaller relative capacities. The bi-abdomens in the Culicoides oxystoma (Schultzei group) were also separated by a speculated third rudimentary abdomen similarly attached to the meta-thorax; both abdomens possess three spermathecae (receptacula seminis) each but two spermathecae in the Culicoides imicola (Imicola group). The dorsal abdomen possesses eleven spiracles while the ventral sac, ten in the Culicoides oxystoma and revealed evidence of functionality; the dorsal abdomen was observed filled while the ventral only shows a smaller content volume. Both bi-abdominal specimens demonstrated no other apparent morphological dysfunction of other parts. On the other hand, the polar gynandromorphic specimen on stereomicroscopy revealed a typical female anterior portion and a posterior portion characteristic of male adult Culicoides. Further examination of the specimen showed absence of spermatheca. These abnormalities are the first reports of any type in invertebrates in Nigeria.

Fitness Parameters

ABSTRACT“CandidatusCardinium hertigii” (Bacteroidetes) is a maternally inherited endosymbiont known from several arthropods. Its mechanisms for persistence in host populations are mostly reproductive manipulation, though it has been occasionally reported to improve fitness parameters in several hosts. InCulicoides(Diptera: Ceratopogonidae) biting midges, the prevalence of “CandidatusCardinium” infection was documented as moderate, with no detectable sex bias. We therefore investigated whether “CandidatusCardinium” affects important fitness parameters, such as survival and body size, inCulicoides imicola, a dominant vector species. Field-collected midges were trapped and analyzed for survival under different environmental conditions and antibiotic treatment, taking into account “CandidatusCardinium” infection status and parity status (i.e., parous or nulliparous). Additionally, wing lengths were measured as a proxy parameter for body size and analyzed together with “CandidatusCardinium” infection data. The findings revealed no difference in survival ofCulicoidesinfected with “CandidatusCardinium” and that of uninfected midges in both parity states and under all tested conditions: optimal, starvation, heat, and antibiotic treatment. Beyond survival, no wing length difference was found for “CandidatusCardinium”-infected versus uninfected midges. In aggregate, these findings support our conclusion that “CandidatusCardinium” does not have an overt effect on the survival and size of adultC. imicolamidges. “CandidatusCardinium” may affect immature stages or may alter adult reproductive performance.

AbstractMansonella ozzardi(Nematoda: Onchocercidae) is a little studied filarial nematode. This human parasite, transmitted by two families of dipteran vectors, biting midges (most of them members of the genusCulicoides) and blackflies (genusSimulium), is endemic to the Neotropical regions of the New World. With a patchy geographical distribution from southern Mexico to north-western Argentina, human infection withM. ozzardiis highly prevalent in some of the Caribbean islands, along riverine communities in the Amazon Basin, and on both sides of the border between Bolivia and Argentina. Studies conducted in Haiti between 1974 and 1984 allowed the first complete description of the adult worm and permitted clarification of the taxonomic position of this filarial species. This paper reports the known geographical distribution ofM. ozzardiin Neotropical regions of the Americas, and focuses on the current situation in Haiti where this filariasis remains a completely neglected public health problem.
