Preferential landing and engorging sites of Culicoides species landing on a horse in Ireland.
Abstract: An investigation of the landing and engorging sites of midges on a bait horse was made in Ireland as part of a project examining the aetiology of sweet itch. Ten species were recovered, seven of which engorged. Culicoides obsoletus and C dewulfi were the most commonly represented, accounting for 89.9 per cent of midges landing and 90.5 per cent of midges engorging. Only 4.69 per cent of midges attracted to the bait were C pulicaris. Overall, the preferential landing sites for midges were along the mane and lower leg regions. Few culicoides were attracted to the head, front and underside of the animal. Two species, C punctatus and C nubeculosus, fed exclusively at the predilection sites of sweet itch but in very small numbers. C pulicaris fed predominantly at these sites also and represented 5.08 per cent of the engorging catch. Of 10,178 midges attracted to the bait, 4097 (40.3 per cent) engorged; the majority of the species taking full blood meals fed on the mane and lower legs. Midges biting in other areas tended to have smaller meals. Areas along the dorsal midline of the body are predilection sites for sweet itch lesions and are preferential engorging sites also. However, considerable engorgement occurred on the lower legs where sweet itch lesions do not occur.

This research article studies the preferred landing and feeding sites of Culicoides, a genus of biting midges, on horses in Ireland. As part of a bigger project examining the etiology of sweet itch (a skin condition in horses), the researchers found that certain species of midges prefer to land and feed on specific locations of a horse.
Species of Culicoides and Their Presence
- The researchers identified a total of 10 species of Culicoides midges during the study.
- Out of these, seven species demonstrated engorgement (blood feeding) on the horse.
- The two most prevalent species were Culicoides obsoletus and C dewulfi, which accounted for 89.9% of midges landing and 90.5% of midges engorging on the horse.
- Culicoides pulicaris made up a smaller proportion of the general midge presence, accounting for only 4.69% of midges attracted to the horse.
Preferential Landing and Engorging Sites
- The majority of midges were found to prefer landing along the mane and lower leg regions of the horse. Fewer were attracted to the head, front, and underside of the animal.
- Two species, C punctatus and C nubeculosus, were observed to feed exclusively at the locations typically affected by sweet itch, though in small numbers. This feeding behavior was also predominantly observed in C pulicaris.
- Out of the total 10,178 midges attracted to the horse, 4097, or 40.3%, engorged on the horse’s blood. These midges primarily fed on the mane and lower leg regions.
- Midges feeding on other areas of the horse took smaller meals, indicating a possible preference for the mane and lower legs.
Correlation with Sweet Itch Lesions
- The dorsal midline of the horse’s body, a common site for sweet itch lesions, was also a preferred site for midges’ engorgement. This suggests that these insects may be contributing to the development of sweet itch in horses.
- Interestingly, a significant amount of engorgement also occurred on the lower legs, which are not typically affected by sweet itch lesions. This finding prompts further investigation into the relationship between midge feeding patterns and the development of sweet itch.
