Abstract

AbstractBovine thelaziasis is a round worm infection that is transmitted by muscidae flies. This investigation was carried out to determine fauna and abundance of veterinary important muscidae flies and to identify Thelazia. spp vectors on cattle farms in Urmia region from 2011 to 2012. Flies were collected by sweep net. The flies’ species were identified by identification keys and suspected flies were immediately desiccated for detect Thelazia spp. infection. In this study, totally 2873 adult flies from 10 families were captured. Among these 63% had belonged to Muscidae family. 4 genera and 8 veterinary important species were identified in this family. Out of these flies Muscina levida (assimilis) was reported for the first time from Iran. Considering their relative abundance the following species were found to be respectively the most abundant: Musca domestica (%33/7), Haematobia irritans (%16/6), M. automnalis (%15/9), Stomoxys calcitrans (%10/5), M. sorbens (%9/4), Muscina stabulans (%2/7), M. crassirostris (%2/5), M. levida (%1/8). The potential vectors of Thelazia spp., M. domestica, M. sorbens, M. automnalis and M. crassirostris were also collected. No infection of Thelazia spp. Larva was observed on examined flies’ samples.
