This study was conducted to investigate the prevalence of mange in sheep in Anbar province by examining 462 heads of sheep. The disease was diagnosed by examining the skin scraping taken from the infected animals in the laboratory. The results showed that sheep were infected with Sarcoptes scabiei parasite, and the total infection rate was 34.6%, and no significant difference was recorded between males 34% and females 35.2%, the highest rate was recorded in the month of January %56 and the lowest in the month of August 13.1%, and the highest rate of infection was 49% in sheep at the age of 6 months - 2 years and significant differences for the rest of the ages. Head and neck lesions recorded the highest infection rate of 28.7 and 34.3% respectively. The study also included the effect of the crude watery extract of Onobrychis ptolemaica on the parasite, concentrations of 2.5-10 mg/ml have significantly affected parasites, it was noted the greater the concentration, the greater the effect during the different treatment periods. The highest concentration of 10 mg /ml resulted in the disappearance of all scabies parasites on day 14 of the treatment. Results showed sheep infection in Anbar province with mange in both sexes, high incidence of infection in young ages, high rate of infection in the winter months, and head lesions recorded the highest percentage of infection, the results showed the effect of concentrations of the crude watery extract of Onobrychis ptolemaica plant largely on the parasite.

This study was conducted to evaluate the efficacy of the fungus Metarhizium anisopliae  as a vital agent for the control of the Hyalomma anatolicum, which is infested on buffalo fields in some villages of Anbar province, Iraq. The results showed that different concentrations of the fungus 4.2*110, 4.2*310, 4.2*510 pg/ml were capable of killing the tick eggs, and the kill rate was proportional to the higher concentrations used. After 3 days of treatment, moreover causing a high proportion of phenotyping deformation in male and female ticks.
