Genetic Structure and Colonization of North America by (Fabricius 1775) (Lepidoptera: Depressariidae) over 15 Years; Contrasts with Westward Expansion of (Goeze, 1783) over 160 Years.

, the purple carrot seed moth, is a Eurasian species first reported in North America in 2008 and currently undergoing range expansion. This invasion follows that of its Eurasion congener (parsnip webworm), first documented in North America 160 years ago. Unlike , which utilizes hostplants across multiple tribes of Apiaceae, is a "superspecialist" effectively restricted in its native and non-indigenous ranges to two closely related apiaceous genera.

Equine Suture Exostosis: A Review of Cases from a Multicenter Retrospective Study.

Suture exostosis is an intriguing and not uncommon pathology that has to be included in the differential diagnosis for horses with swelling of the head. Although several singular case reports have been published, no large case series is available. The aim of this study is to report a multicentric retrospective collection of suture exostosis cases.

Objective: To report the radiographic, surgical and postoperative features in horses with unstable oblique mandibular fractures secured with polyaxial pedicle screws (PPS) external fixation construct and intraoral wiring.

Animals: Three client-owned horses.

Study Design: Short case series.

A Brief History of Equine Dental Practice.

Equine dentistry has been practiced for almost 3000 years, making it one of the oldest areas of equine health care. Progress has been slow and mirrored changes seen in human medical care. Many horsemen practiced equine dentistry during the late nineteenth and early twentieth centuries.

Standing equine dental surgery.

Dental surgeries refer to procedures that affect the dental tissues or their supporting structures. With the development of specific, efficacious, and conservative treatments, morbidity risks have been lowered and chances of benefiting the health of equids improved. Advances in quality of sedation, analgesia, and locoregional anesthesia allow a majority of dental surgeries to be performed in the standing patient.

Incorporating oral photography and endoscopy into the equine dental examination.

This article discusses the significant features and use of digital cameras, intraoral cameras, and oral endoscopes in equine dental practice. Although system features believed to be important have been listed, specific system recommendations have been omitted, since each veterinarian must individually determine the best system to meet practice clinical needs and budget. Veterinarians are encouraged to thoroughly research not only the camera/endoscope purchase but also the capabilities of the entire system, the compatibility of the system with different computer software programs, the reputation and service policies of the manufacturers, and references from other colleagues.
