Equine Culicoides hypersensitivity in Florida: biting midges aspirated from horses.
Abstract: Nine species of Culicoides were aspirated from horses in Florida during the second phase of a study of equine Culicoides hypersensitivity (CHS). Approximately 90% of the 2933 midges were Culicoides insignis Lutz, 4% were C.stellifer (Coquillett), 3% were C.niger Root and Hoffman, 2% were C.alachua Jamnback and Wirth and the remaining 1% included C.venustus Hoffman, C.scanloni Wirth and Hubert, C.lahillei Iches (= C.debilipalpis Lutz), C.pusillus Lutz, and C.edeni Wirth and Blanton. Culicoides were sampled on seven farms located throughout Florida. The location and seasonality of lesion development on horses with CHS correlated with the Culicoides spp. collected directly from the horses as to their sites of attack, their seasonality and geographical distribution.

The research article is about a study conducted in Florida on the hypersensitivity of horses to the bite of various species of midges, particularly Culicoides insignis, which was found to be the most prevalent.
Background
- The researchers conducted a study on the hypersensitivity of horses to a variety of Culicoides, or biting midges, in Florida. This condition, known as Culicoides hypersensitivity (CHS), can cause discomfort and health issues in horses.
Methodology
- The species of Culicoides were collected directly from horses during the second phase of their study. This method allowed them to identify which species were causing hypersensitivity reactions in the horses.
- Approximately 2933 midges were collected, predominantly comprised of Culicoides insignis, constituting 90% of the total midges found. Other species of Culicoides were collected in smaller numbers.
- The midges were sampled from seven farms located throughout Florida. By doing so, the researchers were able to gather a comprehensive dataset that accounted for geographical variety and the potential impact of different environmental conditions.
Results
- The primary result of the study was the identification of various species of Culicoides that were causing the hypersensitivity in horses. The majority of the midges were Culicoides insignis, while other species like C.stellifer, C.niger, C.alachua and a few others were collected in lesser quantities.
- A correlation was found between the location and seasonality of lesion development on horses with CHS and the Culicoides spp. collected from the horses. This indicated the role of specific species at certain sites of attack, their peak season activities, and geographical distribution in causing CHS.
