Abstract

During a cross-sectional prospective epidemiological survey, a total of 2412 sheep were screened for the prevalence of insects. Out of which, 333 (13.80%) were harbored for insects including lice (36.57%), fleas (3.23%) and flies (1.62%). Among the identified species of lice, Haematopinus spp. (44.14%) was predominant followed in order by Damalinia ovis (26.42%) and Linognathus spp. (17.71%). The flea Ctenocepahlides (Ct). felis was more common (4.50%) than Ct. canis (3.30%). Stomoxys calcitrans (3.90%) was the only prevalent specie of fly in the study area. Infestation rate was higher in young sheep (72.68%) as compared to adults (27.32%) and level of infestation was significantly higher in females (75.37%) than males (24.62%). Amongst various breeds of sheep, Cholistani (19.81%) had the highest prevalence followed by Kajli (13.49%), Thalli (12.94%) and Lohi (11.80%). Prevalence of flies (37%) and lice (47%) was highest in December and January, respectively; whereas,that of fleas (39%) reached a peak in April. Among various associated determinants, stall feeding, closed housing, tethered animals and non-cemented floor were found positively associated (P<0.05) with insect infestation. The results showed that insect abundance and the variety of genera were wide in this part of Pakistan. This also causes concern over the emergence of insect-borne diseases in domestic animals.
