culicoides: biological vectors of akabane virus.	akabane virus replicated in culicoides nubeculosus and culicoides variipennis after intrathoracic inoculation and was maintained in both species of midge for at least 9 days post-infection. the virus also replicated to high concentration in c. variipennis after oral infection and was transmitted through a membrane by this species of midge 7-10 days after infection. the experiments described in this paper provided the first definitive evidence that culicoides spp. are able to act as fully compete ...	1989	2609498
distribution of microfilariae of onchocerca lienalis and onchocerca gutturosa in the skin of cattle in germany and their development in simulium ornatum and culicoides nubeculosus following artificial infestation.	onchocerca microfilariae were isolated form the umbilicus and neck of 438 cow hides at the abattoir in tübingen, f.r.g. the overall onchocerca infection rate was 40.4%. the presence of onchocerca lienalis and o. gutturosa microfilariae, which are difficult to distinguish by morphological criteria, was retrospectively demonstrated after artifically infesting simulium ornatum and culicoides nubeculosus and identifying the infective larvae recovered. nine of 16 samples of umbilical microfilariae fe ...	1990	2399652
morphology of the antennae of two species of biting midge: culicoides impunctatus (goetghebuer) and culicoides nubeculosus (meigen) (diptera, ceratopogonidae).	scanning and transmission electron microscopy of the antennae of culicoides impunctatus and culicoides nubeculosus show that males and females share five sensillum types. sensilla chaetica resemble mechanoreceptors, each innervated by a single neurone whose dendrite terminates distally in a tubular body: the arrangement of sensilla on male antennae suggests that females are located by sound. the antennae have both sharp- and blunt-tipped sensilla trichodea, sharp-tipped sensilla on only the dist ...	1992	1518067
the multiplication of african horse-sickness virus in two species of culicoides (diptera, ceratopogonidae).	type 9 african horse-sickness virus multiplied to a high titre in both culicoides nubeculosus and c. variipennis after intrathoracic inoculation and in c. variipennis after oral ingestion. the orally infected c. variipennis were able to transmit the virus by biting after 13 days incubation at 26 degrees c but not after 6 days incubation. intrathoracically inoculated c. variipennis were able to transmit the virus after 4 days incubation. it is suggested that c. variipennis can act as a biological ...	1975	1169931
a mass attack by the biting midge culicoides nubeculosus (mg.) (dipteria, ceratopogonidae) on grazing cattle in denmark. a new aspect of sewage discharge.	a consequence of sewage discharge into a shallow marsh pool was large-scale hatching of the biting midge culicoides nubeculosus from the recipient and mass attacks by this blood-sucking insect on grazing cattle. culicoides nubeculosus is a great nuisance due to the painful bite and in denmark it is a potential vector of pathogenic agents. in the future, these aspects of sewage discharge must be borne in mind.	1975	1161452
studies on onchocerca cervicalis railliet and henry 1910: v. the development of onchocerca cervicalis larvae in the vectors.	colonies of culicoides nubeculosus and c; variipennis were established at winches farm field station, st. abans. both species of midge were found to be susceptible to infection with onchocerca cervicalis microfilariae. infection was achieved either by engorging through a chick skin membrane on a suspension of microfilariae in blood, or by feeding upon a horse naturally infected with o. cervicalis microfilariae. a large proportion of the microfilariae ingested by the midges penetrated into the ha ...	1975	1127216
