Pakistan Punjab Eyaletindede Keçi Nokra Enfestasyonunun Prevalansı Üzerine Epidemiyolojik Bir Çalışma

The purpose of the present study was to determine the prevalence of Warble Fly Infestation (WFI) in goats of Punjab Province, Pakistan. Goat warble fly infestation is caused by Przhevalskiana silenus (Diptera: Oestridae). There were a total of five hundred animals examined from July 2012 to January 2013 from Khoshab and Chakwal districts of Punjab province for the prevalence of warble. The larvae were collected from the infested goats and identified as P. silenus. The results showed that the prevalence of GWFI was 17.8% (89/500). The number of nodules in the infested animals ranged from 1-14 (6.61±2.4). The breed wise prevalence was in beetle breed (13.2%), local breed (18%) and desi breed (22.9%), respectively. The sex wise prevalence was in male (15.3%) and in female (19.4%). The prevalence based on age showed that the rate of infestation in animals having age group (1-3 year) was 20.9%, (4-6 year) was 14.6% and (>6 year) was18.1%, respectively. The present study showed that these epidemiological factors have a significant effect on the prevalence of WFI in goats of Punjab Province. The results showed the effect of different treatments given to animals on the basis of sex, age groups, infested and non-infested animals. The results of this survey showed that the fly is active from March to June. It was first study on GWFI in Punjab Province; northern part of Pakistan. It would be very helpful in devising the future strategies towards the eradication and control of warble fly in other endemic areas of Pakistan.
