Two thousand and two heads obtained from slaughtered sheep at the Fars abattoirs (Shiraz, Southern Iran) between April 2006 and April 2007 were examined for the presence of Oestrus ovis larvae. Of the total heads, 995 (49.7%) were infested with O. ovis larvae. O. ovis larvae were observed in both sexes and all age groups in each season of the year. A total of 6264 larvae were collected. The overall larval intensity for the infested sheep was 6.3, with 3.9 in spring, 5.3 in summer, 5.9 in autumn and 7.8 in winter. Prevalence ranged from 23.3% in spring to 80% in winter. Increased infestation was observed in older animals.

Duddingtonia flagrans is a nematode-trapping fungus that is widely used to control parasitic nematodes in livestock. After oral ingestion and passage through the digestive tract of animals, this microorganism captures nematodes in feces. Although many researchers have examined the safety of this fungus for humans, animals, and the environment, few reports have discussed the safety of nematode-trapping D.

Control of the sheep blowfly relies on insecticides, however resistance is currently impacting on their efficacy. The use of insecticides in combination (mixtures) is considered to be a useful strategy to delay resistance under some circumstances. The present study aimed to examine the combination of spinosad with macrocyclic lactones in order to determine if the two drug classes showed any interactions that would impact on the usefulness of a combination product for flystrike control.
