    Abstract:
    Genital infestations caused by Wohlfahrtia magnifica (Schiner, 1862) has been reported as being a common problem encountered in female camels in the Gobi desert. Thus, a field investigation to establish the prevalence of wohlfarthiosis in camel herds in the eastern Gobi district was carried out between May and July 1994. The objectives of the study were to establish the relevance of genital myiasis, and to describe the disease patterns, clinical course and pathomorphological changes associated with it. The field study was designed to suit the specific ecological, infrastructural and logistic conditions. Two cross-sectional samples were taken from 45 selected herds in six different areas of the Chatanbulag Sumon to obtain data on herd structure, age distribution, and the breeding history of infested female animals. Post partum events and previous occurrence of genital myiasis were recorded by use of a standardised questionnaire. Clinically infested animals were first detected visually. All camels to be investigated further were subsequently immobilised using ropes and the genitals were examined for tissue lesions and the presence of larvae. Examination of 1676 Bactrian camels from 45 selected herds in six different areas of the Chatanbulag Sumon in the Eastern Gobi district, Mongolia, led to an estimate of Wohlfahrtia magnifica infestation rates between 8-10%. Most myiasis cases were found in older females (> 4 yr), younger animals were infested at a lower rate. Highest prevalence rates were discovered during June and July, highest levels of infestation occurred in the Aman Us Chudak region with infestation rates up to 15%.
