Repellency of synthetic and plant-derived preparations for Culicoides imicola

Medical and Veterinary Entomology, 1997
Abstract The study was conducted to find a safer and longer lasting repellent for C. imicola than di‐ethyl toluamide (DEET), to validate whether the current recommendations in Israel for application of repellents during an outbreak of disease caused by pathogens borne by

Assessment of the Hemotek® system for the in vitro feeding of field‐collected Culicoides imicola (Diptera: Ceratopogonidae) in South Africa

Medical and Veterinary Entomology, 2020
The optimising and standardisation of in vitro blood feeding protocols for field‐collected Culicoides species (Diptera: Ceratopogonidae) will be of essence for the comparison of the vector competencies of various populations of viruses of veterinary ...

The applicability of spectrophotometry for the assessment of blood meal volume inartificially fed Culicoides imicola in South Africa

Medical and Veterinary Entomology, 2020
The volume of the blood meal of haematophagous insects will determine the number of infective particles taken up during feeding and may as such denote the minimum dose needed to infect a competent vector.

Mosquito Repellent Attracts Culicoides imicola (Diptera: Ceratopogonidae)

Journal of Medical Entomology, 1999
A plant-derived mosquito repellent, based on the oil of Eucalyptus maculata var. citriodora Hook, was evaluated against the biting midge Culicoides imicola Kieffer. Suction black light-traps covered with repellent-impregnated polyester mesh and deployed near horses attracted large numbers of C. imicola, which were seen near the treated net within a few

Global potential distribution and realized niche conservatism during biological invasion of Culicoides imicola from Africa to the Mediterranean basin of Europe.

Acta Tropica
Many Culicoides species transmit arboviruses that affect animals and humans. Culicoides imicola, a key vector of bluetongue virus (BTV), has expanded its range from Africa to Europe, spreading disease.

Biotic and abiotic factors shape the microbiota of wild‐caught populations of the arbovirus vector Culicoides imicola

Insect molecular biology (Print), 2018
Biting midges of the genus Culicoides are known vectors of arboviruses affecting human and animal health. However, little is known about Culicoides imicola microbiota and its influence on this insect’s biology.

Studies of the mortality rate of Culicoides imicola in Morocco

1998
Daily mortality rates of female Culicoides imicola were found for eight sites in Morocco in 1994 and for six sites in 1995. The mortality rates were found by operating Pirbright-type light traps for a number of consecutive nights in late summer or autumn and finding the parous rate assuming a feeding interval of 3 to 5 days.

The Effect of Climate on the Presence of Culicoides imicola in Italy

Journal of Veterinary Medicine, Series B, 2003
SummaryA model was developed to classify the Italian territories in relation to their suitability to harbour populations of Culicoides imicola and, as a consequence, also able to sustain a bluetongue (BT) epidemic. Italy was subdivided into 3507 10 × 10 km cells. In 546 cells at least one collection was made.

Immunogenicity and Allergenicity of Culicoides imicola (Diptera: Ceratopogonidae) Extracts

Journal of Veterinary Medicine, Series B, 1990
SummarySummer seasonal recurrent dermatitis (SSRD) or “sweet itch” is a seasonally occurring allergic dermatitis of horses provoked by biting midges. The allergic skin reactions have been attributed to allergens present in various Culicoides species. C. imicola is the suspected etiological agent of SSRD in Israel.

The relationship between climate and the distribution of Culicoides imicola in Iberia

1998
The biting midge Culicoides imicola was captured at 17 of 27 farms in Spain and Portugal during a survey of its distribution following outbreaks of African horse sickness in Iberia that occurred between 1987 and 1990. Farms were sampled approximately twice weekly from October 1992 to February 1995.
