Myiasis caused by Hypodermatinae flies is an economically important disease affecting domesticated and wild ruminants in countries of the Mediterranean and Indian subcontinent. The adult flies have a short life span of 1 week, and they spread disease by laying their eggs on the coat of animals. Hypoderma spp. primarily lay their eggs on cattle, buffalo, roe deer, red deer and reindeer, while Przhevalskiana spp. lay eggs on the coat of goats. The larvae live as tissue parasites, inducing myiasis in the host, and have a major impact on the productivity and welfare of infested animals. Diagnosis of myiasis is mainly based on clinical examination of the animal and immunodiagnosis using serum and milk samples. Chemical control of this pest is considered the best treatment option. Treatment with microdoses of ivermectin (2μg/kg body weight) combined with immunosurveillance strategies has led to the eradication of bovine hypodermosis in a few countries; however, these flies are still prevalent throughout the northern hemisphere. This paper reviews the current status, diagnosis and control measures for Hypodermatinae myiasis of domestic and wild ruminants in the Indian subcontinent and Mediterranean region.
