| field studies on culicoides (diptera: ceratopogonidae) activity and response to deltamethrin applications to sheep in northeastern spain. | an enclosure trapping experiment compared numbers and engorgement of culicoides spp. taken from treated sheep (7.5% deltamethrin) to culicoides from untreated sheep. attack rates were low (0.2/min), but 58% of culicoides obsoletus s.l. and 67% of culicoides parroti kieffer engorged on untreated sheep, and no engorgement occurred on treated sheep on 0 and 4 d posttreatment. a uv light trap in a livestock barn collected eight culicoides spp. (510 individuals), dominated by c. obsoletus (meigen) (6 ... | 2010 | 20180316 |
| host preferences of ornithophilic biting midges of the genus culicoides in the eastern balkans. | many biting midges of the genus culicoides latreille, 1809 (diptera: ceratopogonidae) are competent vectors of a diverse number of pathogens. the identification of their feeding behaviour and of vector-host associations is essential for understanding their transmission capacity. by applying two different nested polymerase chain reaction (pcr) assays, of which one targeted the avian cyt b gene and the other targeted the coi gene of a wide range of vertebrates, we identified the blood hosts of six ... | 2015 | 25689114 |
| degree of associations among vectors of the genus culicoides (diptera: ceratopogonidae) and host bird species with respect to haemosporidian parasites in ne bulgaria. | the occurrence of haemosporidians in biting midges of the genus culicoides is examined in north-east bulgaria in order to reveal their potential role for parasite transmission. a pcr-based technique amplifying part of the mitochondrial cytochrome b gene of the parasite is applied on naturally infected biting midges. totally, 640 parous individuals of four species and 95 blood-fed individuals of six species of culicoides are examined for the presence of dna of haemosporidians. haemosporidian gene ... | 2014 | 25280514 |
